A pharmaceutical company needs 5.00 moles of epinephrine (C9H13NO3) for a new EpiPen they hope to put on the market. How many grams of adrenaline will the lab need for a shipment of 30.0 Epipens to be made?

Answer:

(B) HNO3 + NaOH

Explanation:

Hello,

In this case, for the production of sodium nitrate a substance having the sodium as a cation should react with another substance having the nitrate anion. Moreover, neutralization reactions are carried out when bases react with acids, such is the case of nitric acid and sodium hydroxide:

\(NaOH+HNO_3\rightarrow NaNO_3+H_2O\)

Thus, the answer is (B) HNO3 + NaOH  as the other options involve salts rather than acids or bases as starting reactants.

20.0 moles of oxygen react with Antimony to form 13.3 moles of Antimony (III) Oxide. We want to calculate how many moles of Antimony (III) Oxide will be formed from 20.0 moles of oxygen. This is a stoichiometry problem.

The link between the proportional amounts of components participating in a reaction or generating a compound is known as stoichiometry, and it is often expressed as a ratio of whole integers.

Assuming a balanced chemical equation, the stoichiometric ratio between Antimony (III) Oxide  and oxygen can be used to determine the number of moles of Antimony (III) Oxide  formed.

For example, the balanced equation for the reaction of Antimony with O2 to form Antimony (III) Oxide  is:

4 Antimony + 3 O2 → 2 Antimony (III) Oxide

From this equation, it can be seen that 3 moles of oxygen react with 2 moles of Antimony (III) Oxide . Therefore, if there are 20.0 moles of O2, then the number of moles of Antimony (III) Oxide  formed would be:

20.0 moles oxygen × (2 moles Antimony (III) Oxide  / 3 moles oxygen) = 13.3 moles Antimony (III) Oxide.

When the equilibrium constant is higher than one, it indicates that the reaction prefers to produce products, whereas if the equilibrium constant is less than one, it indicates that the reaction prefers to produce reactants. If the equilibrium constant is equal to one, the reaction proceeds in both directions equally.

In a chemical reaction, exothermic reactions are defined as reactions that release heat into their environment. It implies that heat is given off when reactants are converted to products. At equilibrium, an exothermic reaction continues to be exothermic, meaning that heat is given off even after the reaction reaches a state of equilibrium.There are two types of reactions: exothermic and endothermic.

A reaction is classified as exothermic if it releases heat, and endothermic if it absorbs heat. The direction of the reaction is determined by whether it is exothermic or endothermic. At equilibrium, the reaction is no longer moving forwards or backwards. It's also worth noting that reactions can be exothermic in one direction and endothermic in the other.

The equilibrium constant (K) is defined as the ratio of the concentration of products to the concentration of reactants in the chemical reaction equation. It is used to express how much of the products is generated by the reaction in comparison to the reactants.  the equilibrium constant aids in the identification of the direction in which the reaction will proceed at equilibrium.

The pH of a 0.250 M solution of HOC6H5 is 2.92 and HCN is 5.96

a. HOC6H5, or benzoic acid, is a weak acid that partially dissociates in water to form H+ and C6H5COO- ions. The dissociation reaction is

HOC6H5 ⇌ H+ + C6H5COO-

To determine the pH of a 0.250 M solution of benzoic acid, we need to calculate the concentration of H+ ions in solution. The equilibrium expression for the dissociation reaction is:

Ka = [H+][C6H5COO-]/[HOC6H5]

where Ka is the acid dissociation constant for benzoic acid. The value of Ka for benzoic acid is 6.5 × \(10^-5.\)

We can assume that the initial concentration of H+ ions in the solution is zero. At equilibrium, let x be the concentration of H+ ions in solution and 0.250 - x be the concentration of C6H5COO- ions in solution. Then:

Ka = x(0.250 - x)/0.250

Solving for x, we get:

x = 1.21 × \(10^-3\) M

the pH of a 0.250 M solution of benzoic acid is:

pH = -log[H+] = -log\((1.21 × 10^-3)\) = 2.92

b. HCN, or hydrocyanic acid, is also a weak acid that partially dissociates in water to form H+ and CN- ions. The dissociation reaction is:

HCN ⇌ H+ + CN-

To determine the pH of a 0.250 M solution of HCN, we need to calculate the concentration of H+ ions in solution. The equilibrium expression for the dissociation reaction is:

Ka = [H+][CN-]/[HCN]

where Ka is the acid dissociation constant for HCN. The value of Ka for HCN is 4.9 ×\(10^-10\).

We can assume that the initial concentration of H+ ions in the solution is zero. At equilibrium, let x be the concentration of H+ ions in solution and 0.250 - x be the concentration of CN- ions in solution. Then:

Ka = x(0.250 - x)/0.25

Solving for x, we get:

x = 1.1 × \(10^-6\) M

The relationship between a reaction's products and reactants with regard to a certain unit is expressed by the equilibrium constant, K.

Thus, When a reaction is homogeneous, all of the products' and reactions' states of matter are the same (the prefix "homo" means "same"). The solvent typically controls the reaction's overall state of matter.

When a reaction is in chemical equilibrium, the concentrations of the reactants and products do not significantly fluctuate over time. A double arrow between the reactants and products denotes these reversible reactions.

As described, this reaction is endothermic, therefore when heat is added, the equilibrium constant moves to the right.  In turn, this turns the solution blue.  Cl- is drawn out of solution by the addition of AgNO3.

The total kilojoules in two tablespoons is  836.8 kJ.

To determine the total kilojoules in two tablespoons of a substance, we need to know the specific substance and its energy content per tablespoon. Different substances have different energy values, so without this information, it is not possible to provide an accurate calculation.

The energy content of food or substances is typically measured in kilocalories (kcal) or kilojoules (kJ). 1 kilocalorie is equal to 4.184 kilojoules. The energy content of a substance is often listed on food labels or in nutritional databases.

For example, if we have the energy content of a substance as 100 kilocalories (kcal) per tablespoon, we can convert it to kilojoules by multiplying it by 4.184:

100 kcal * 4.184 kJ/kcal = 418.4 kJ

So, if we have two tablespoons of this substance, the total energy would be:

418.4 kJ/tablespoon * 2 tablespoons = 836.8 kJ

It's important to note that the energy content of a substance can vary depending on its composition, density, and other factors. Therefore, it is always recommended to refer to reliable sources such as food labels, nutritional databases, or consult a qualified professional to obtain accurate information regarding the energy content of specific substances.

The correct conversion factor when converting from moles to liters is the molar volume at a given temperature and pressure.

This value is dependent on the ideal gas law and can be determined using the ideal gas equation PV = nRT, where P represents pressure, V represents volume, n represents the number of moles, R is the ideal gas constant, and T is the temperature in Kelvin.

The molar volume of an ideal gas at standard temperature and pressure (STP), which is 0 degrees Celsius (273.15 Kelvin) and 1 atmosphere (101.3 kilopascals), is approximately 22.4 liters per mole.

Therefore, to convert moles to liters, you can multiply the number of moles by the molar volume at STP, which gives you the volume in liters.

It's important to note that the molar volume is an approximation and assumes ideal gas behavior.

Additionally, if you are working with gases at different temperatures and pressures, you would need to use the appropriate molar volume value corresponding to the given conditions.

Iron released 2.495 joules of heat.

To calculate the amount of heat absorbed or released by 90.23g of iron, we need to use the specific heat of iron and the change in temperature.

Iron has a specific heat capacity of 0.45 J/g °C, which means that it takes 0.45 Joules of energy to raise the temperature of 1 gram of iron by 1 degree Celsius.

First, we need to convert the mass of iron from grams to kilograms.

Iron mass = 90.23 g = 0.09023 kg

Now we need to calculate the temperature change. The initial temperature of the iron is T = 86°C, but the final temperature is unknown. Assuming that the iron undergoes a process that neither loses nor gains heat through the environment, the following equation can be used.

heat absorbed = heat released

This means that the amount of heat absorbed by iron is equal to the amount of heat given off by the environment. So you can use the following formula:

Heat absorption = mass x specific heat capacity x temperature change

Since there is no heat loss or gain to the environment, we can assume that the temperature of the environment is constant at 25°C. So the temperature change is:

temperature change = final temperature - initial temperature

Temperature change = 25°C - 86°C

Temperature change = -61°C

Note that the temperature change is negative because iron loses heat.

Now you can insert the value.

Heat absorbed = 0.09023 kg × 0.45 J/g °C × (-61 °C)

heat absorbed = -2.495 J

Since the value is negative, this indicates that the iron lost heat to the environment and the environment gained heat.

Answer: 4.88 g/mol. and helium

Explanation:

To find the molar mass of the gas, we can use the ideal gas law equation which is PV=nRT where:

P = pressure = 2.000 atm

V = volume = 50.00 L

n = number of moles

R = gas constant = 0.08206 L·atm/K·mol

T = temperature = 273.15 K

First, we need to find the number of moles of the gas:

PV = nRT

n = PV/RT

n = (2.000 atm)(50.00 L)/(0.08206 L·atm/K·mol)(273.15 K)

n = 1.844 mol

Now, we can find the molar mass of the gas by dividing its mass by the number of moles:

molar mass = mass/number of moles

mass = 9.00 g

molar mass = 9.00 g/1.844 mol

molar mass = 4.88 g/mol

Therefore, the molar mass of the gas is 4.88 g/mol.

To determine what gas this is, we can compare the molar mass of the gas to the molar masses of known gases. The molar mass of 4.88 g/mol is closest to that of helium (4.00 g/mol). Therefore, this gas is most likely helium.

Based on Le Châtelier's principle, when a system in equilibrium change a condition, the system will produce a reaction in order to subtract the effect of the initial change.

For the equilibrium:

2Cl2 (g) + 2H2O (g) + heat ↔ 4HCl (g) + O2 (g)

I. Adding some Cl₂. Will produce the equilibrium shifts to the right in order to decrease the concentration of Cl₂ and produce more HCl.

II. raising the temperature at constant pressure. As the system requires heat to produce the reaction, the system will shift to the right in order to decrease the heat and produce more HCl

III. decreasing the volume at constant temperature. As the volume decreases, the pressure increases. In the left, there are 4 moles of gas and in the right there are 5. When the pressure increases the system will try to decrease the moles of gas in order to decrease the pressure. THat means the system will shift to the left in order to produce more Cl₂
