Claim 2: Temperature and motion of gas molecules have an inverse relationship (As one value goes up, the other value goes down).
Why is the claim correct?This claim is correct because temperature is a measure of the average kinetic energy of the gas molecules, and as the temperature increases, the gas molecules move faster and have more kinetic energy.
Conversely, as the temperature decreases, the gas molecules move slower and have less kinetic energy. This relationship is described as inverse because as one value (temperature) increases, the other value (particle motion) decreases.
For example, when a gas is heated, the temperature increases, and the gas molecules move faster, resulting in an increase in particle motion. Conversely, when a gas is cooled, the temperature decreases, and the gas molecules move slower, resulting in a decrease in particle motion.
Another example is the relationship between the temperature and pressure of a gas in a container. When the temperature of the gas increases, the pressure also increases because the gas molecules move faster and collide with the container walls more frequently and with more force.
The evidence supports the claim that temperature and motion of gas molecules have an inverse relationship because the data collected shows that as the temperature of the gas increases, the average velocity of the gas molecules also increases, indicating an increase in particle motion.
Similarly, as the temperature decreases, the average velocity of the gas molecules decreases, indicating a decrease in particle motion.

Using the following equation, determine the % yield from the following reaction if 3.050E1 g of
octane (C8H18) react with excess oxygen to produce 8.179E1 g of CO₂ (g).
2C8H18 (1) +2502(g) → 16CO2 (g) + 18H₂O(l)
Answers
The percent yield is 86.1%.
How do we obtain the percent yield?The percent yield is a measure of the efficiency of a chemical reaction and is calculated by comparing the actual yield of a reaction to the theoretical yield that could be obtained based on stoichiometry. The percent yield is expressed as a percentage and is calculated using the following formula:
Percent yield = (Actual yield ÷ Theoretical yield) x 100%
We can see;
Number of moles of octane = 3.05 * 10^1/114 g/mol
= 0.27 moles
Then from the reaction equation;
2 moles of octane produces 16 moles of CO2
0.27 moles of octane would produce 0.27 * 16/2
= 2.16 moles
Theoretical yield of the product = 2.16 moles * 44 g/mol
= 95 g
Thus we have that;
% yield = 8.179 * 10^1 g/95 g * 100/1
= 86.1%

Answers
Answer:
The volume of Component 1 is 36 cubic inches.
Explanation:
To calculate the volume of a composite solid, we need to determine the individual volumes of the different components and then add them together.
In this case, the composite solid consists of multiple components with the following dimensions:
Component 1:
Length: 4 inches
Width: 3 inches
Height: 3 inches
To find the volume of Component 1, we multiply the length, width, and height together:

A gas has a volume of 550 mL at a temperature of -55 °C. The volume of the gas at 30 °C is
Blank 1:
mL.
Answers
The combined gas law equation is:
(P1 * V1) / (T1) = (P2 * V2) / (T2)
The volume of the gas at 30 °C is approximately 760.67 mL.
To determine the volume of the gas at 30 °C, we can use the combined gas law equation, which relates the initial and final conditions of temperature and volume for a gas.
The combined gas law equation is:
(P1 * V1) / (T1) = (P2 * V2) / (T2)
Where:
P1 and P2 are the initial and final pressures, respectively
V1 and V2 are the initial and final volumes, respectively
T1 and T2 are the initial and final temperatures in Kelvin, respectively
We need to convert the temperatures from Celsius to Kelvin by adding 273.15 to each value.
Given:
V1 = 550 mL
T1 = -55 °C = 218.15 K
T2 = 30 °C = 303.15 K
Assuming the pressure remains constant, we can rearrange the equation to solve for V2:
V2 = (P1 * V1 * T2) / (P2 * T1)
Since the pressure is not specified in the problem, we can assume it remains constant, allowing us to cancel out the pressure terms. Thus, the final equation becomes:
V2 = (V1 * T2) / T1
Plugging in the given values:
V2 = (550 mL * 303.15 K) / 218.15 K
Simplifying the calculation, we find:
V2 ≈ 760.67 mL
Therefore, the volume of the gas at 30 °C is approximately 760.67 mL.

Final temperature =
Answers
m1c1ΔT1 + m2c2ΔT2 = 0
where m1 and m2 are the masses of the two samples of water, c is the specific heat of water, and ΔT is the change in temperature. We can assume that the final temperature of the water is T.
Plugging in the values, we get:
(49.0 g)(4.184 J/g °C)(T - 100. °C) + (55.0 g)(4.184 J/g °C)(T - 25. °C) = 0
Simplifying and solving for T, we get:
T = [ (49.0 g)(4.184 J/g °C)(100. °C) + (55.0 g)(4.184 J/g °C)(25. °C) ] / [ (49.0 g)(4.184 J/g °C) + (55.0 g)(4.184 J/g °C) ]
T = 39.4 °C

Answers
The equilibrium concentration of NO₂ at this temperature is approximately 0.219 M.
To determine the equilibrium concentration of NO₂, we can use the equilibrium constant expression (Kc) and the given equilibrium concentrations of NO and O₂. The equilibrium constant expression for the given reaction is:
Kc = ([NO₂]²) / ([NO]²[O₂])
We are given the equilibrium concentrations of NO and O₂ as [NO] = 0.31 M and [O₂] = 1.10 M, respectively. We need to find the equilibrium concentration of NO₂, denoted as [NO₂].
Using the given equilibrium concentrations and the equilibrium constant expression, we can rearrange the equation and solve for [NO₂]:
Kc = ([NO₂]²) / ([NO]²[O₂])
0.50 = ([NO₂]²) / ((0.31 M)²(1.10 M))
0.50 = ([NO₂]²) / (0.0961 M³)
Multiplying both sides by 0.0961 M³, we have:
0.04805 M³ = [NO₂]²
Taking the square root of both sides, we find:
[NO₂] = √(0.04805 M³)
[NO₂] ≈ 0.219 M
Therefore, the equilibrium concentration of NO₂ at this temperature is approximately 0.219 M.
It's important to note that the units of concentration (M) were used throughout the calculations, and the answer is rounded to three significant figures based on the given data.
Additionally, the negative sign of the enthalpy change (AH) indicates an exothermic reaction, and the equilibrium constant (K) of 0.50 suggests that the reaction favors the products, as the concentration of NO₂ is greater at equilibrium.

A number present on the front of an atom, ion or molecule in a chemical reaction equation is called a stoichiometric coefficient.
For example, \(H_{2}O(l) \rightarrow H_{2}(g) + \frac{1}{2}O_{2}(g)\)
Here, the stoichiometric coefficient for \(H_{2}O(l)\) is 1, for \(H_{2}(g)\) is 1 and for \(O_{2}\) is \(\frac{1}{2}\).
Thus, we can conclude that the stoichiometric coefficient for oxygen is \(\frac{1}{2}\).

Ammonium perchlorate nh4clo4 is the solid rocket fuel used by the u.s. space shuttle. it reacts with itself to produce nitrogen gas n2 , chlorine gas cl2 , oxygen gas o2 , water h2o , and a great deal of energy. what mass of oxygen gas is produced by the reaction of 3.1g of ammonium perchlorate?
Answers
0.9792 g of \(O_2\) is produced by the chemical reaction of 3.1 g of ammonium perchlorate.
What is chemical reaction ?
A chemical reaction is a process that leads to the transformation of one set of chemical substances to another.
The balanced chemical equation for the reaction of ammonium perchlorate and the products formed is:
\(NH_4ClO_4 \rightarrow N_2 + Cl_2 + O_2 + 2H_2O\)
From the equation, we can see that for every one mole of ammonium perchlorate that reacts, one mole of \(O_2\) is produced.
To find the mass of \(O_2\) produced by the reaction of 3.1 g of ammonium perchlorate, we need to first calculate the number of moles of ammonium perchlorate present:
molar mass of \(NH_4ClO_4 = NH_4 (1 * 4 + 14) + Cl + 4O (16 * 4) = 101.5 g/mol\)
moles of \(NH_4ClO_4 = mass / molar mass = 3.1 / 101.5 = 0.0306 mol\)
Since the mole ratio of \(NH_4ClO_4\) to \(O_2\) is 1:1, the number of moles of \(O_2\)produced is also 0.0306 mol.
Finally, we can calculate the mass of \(O_2\) produced using its molar mass:
molar mass of \(O_2\) = 32 g/mol
mass of \(O_2\) = moles of \(O_2\) × molar mass of \(O_2\)
= 0.0306 mol × 32 g/mol
= 0.9792 g
Therefore, 0.9792 g of \(O_2\) is produced by the reaction of 3.1 g of ammonium perchlorate.

Answers
The electrons move from left to right through the circle labeled "M" to reach the cathode, where reduction takes place.
If oxidation occurs on the left side of the fuel cell and reduction occurs on the right side, the movement of electrons can be described as follows: Electrons move from left to right through the circle labeled "M."
In a fuel cell, the process of oxidation takes place at the anode (labeled A) where the fuel is oxidized, releasing electrons. These electrons then flow through the external electrical circuit, represented by the wire connecting objects A and B. The electrons reach the cathode (also labeled A) on the right side of the cell, where reduction occurs.The circle labeled "M" represents the membrane or electrolyte in the fuel cell. This membrane allows the transport of ions but blocks the movement of electrons. As a result, electrons cannot flow directly through the electrolyte but must travel through the external circuit.
This movement of electrons through the external circuit is what generates an electric current that can be used to power electrical devices or systems.
