The term that the scientist would use in this case is partial pressure. Option D

The pressure that one particular gas component within a mixture of gases exerts is referred to as partial pressure. It is the pressure that the gas would experience at the same temperature if it were the only thing in the entire volume.

When researching gas mixtures, such as in gas laws, gas phase equilibria, and gas collecting methods, partial pressures are extremely crucial for the gas.

Taking into account the definition of dilution, the final concentration after two dilutions is 0.296 M.

Dilution is the reduction in concentration of a chemical substance in a solution. This is accomplished by adding more solvent to the solution at the same amount of solute.

The amount of solute does not change, but as more solvent is added, the concentration of the solute decreases, as the volume of the solution increases.

A dilution is mathematically expressed as:

Ci×Vi = Cf×Vf

where

In this case, you have a first dilution where you know:

Replacing in the definition of dilution:

1.70 M× 78 mL= Cf× 218 mL

Solving:

(1.70 M× 78 mL)÷ 218 mL= Cf

0.608 M= Cf

A 109 mL portion of that solution is diluted by adding 115 mL of water. So, you have a second dilution where you know:

Replacing in the definition of dilution:

0.608 M× 109 mL= Cf× 224 mL

Solving:

(0.608 M× 109 mL)÷ 224 mL= Cf

0.296 M= Cf

In summary, the final concentration is 0.296 M.

The number of moles of the gas can be determined using ideal gas equation. The number of moles of Br gas in 2.8 L at 1.38 atm and 327 K is 0.144 moles.

Ideal gas law states the relation between temperature, pressure and volume with the number of moles of a gas as written below:

PV = nRT

where, R is the universal gas constant equal to 0.082 L atm/K mol

Given that, T = 327 K

P = 1.38 atm

V = 2.8 L.

Then, n = PV/RT

Number of moles of Br gas, n = (1.38 atm ×2.8 L)/(327 K × 0.082 L atm/K mol ) = 0.144 moles.

Therefore, the number of moles of Br gas in in 2.8 L at 1.38 atm and 327 K is 0.144 moles.

Taking into account the definition of calorimetry, the heat Q when 22.0 g of water is heated from 40.0°C to 100.0°C is 5,525.52 J.

Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.

When heat added or removed from a substance causes a temperature change in it without affecting its molecular structure, it is called sensible heat.

In other words, sensible heat is the calorific energy that, supplied or removed from a body or an object, causes its temperature to change without affecting its molecular structure and therefore its phase.

The expression for sensible heat is:

Q = c× m× ΔT

where:

In this case, you know:

Replacing in the definition of sensible heat:

Q = 4.186 J/gC× 22 g× 60 °C

Magnesium is not a good conductor. Hence, the conductivity of magnesium is not good.

Magnesium is placed in group 2 of the periodic table. It has 2 valence electrons which are in the fully filled s-subshell. When the subshell is fully filled, the electrons are not available to move to conduct. For example, group 1 has half filled subshell which allows the electrons to move.

But, how does magnesium conduct? As its subshell is fully filled and therefore no electrons are available to move.

In group 2 metals, there is a property called s-p hybridization. The s- and p- subshells overlap so that metals can now move to the unfilled states of the p-subshell.

Hence, magnesium is not a good conductor.

It would require approximately 600 kilojoules of energy to vaporize 2 kg of copper.

To calculate the energy required to vaporize a substance, we need to consider the heat of vaporization, which is the amount of energy required to convert a given amount of substance from its liquid state to its gaseous state at a constant temperature.

The heat of vaporization for copper is approximately 300 kJ/kg (kilojoules per kilogram) at its boiling point, which is around 2567 degrees Celsius (4649 degrees Fahrenheit). This means that for every kilogram of copper, 300 kJ of energy is needed to vaporize it.

Given that you have 2 kg of copper, we can calculate the total energy required as follows:

Energy = Heat of Vaporization × Mass

Energy = 300 kJ/kg × 2 kg

Energy = 600 kJ

Therefore, it would require approximately 600 kilojoules of energy to vaporize 2 kg of copper.

It's worth noting that the heat of vaporization can vary slightly depending on the purity of the copper and the specific conditions, such as temperature and pressure. The value provided here is an approximation. Additionally, it's important to handle copper and any high-temperature processes with caution, as they can pose safety hazards.

Answer:

The type of music each plant listens to.

Explanation:

A variable is any factor or condition whose value is changing in an experiment. A variable can occur in different types or quantity, and three types of variable (independent, dependent, and controlled) can be found in an experiment. In the experiment described above, "the type of music each plant listens to" is the variable. It is an independent variable whose value is changing because it exists in different types and it is the one that the student is observing its effect on the plant’s growth. In this experiment, this variable which differ will also produce different results (or effects).

At equilibrium, the HI concentration is 2.92 mol/L.

For the process H2(g)+CO2(g)updownarrow H2O+CO. at 1660 °C, the equilibrium constant KP is 4. In a 5 liter flask, 0.8 moles each of H2 and CO2 are first injected. Reactions occur in the following order with relation to H2: 1. In experiments 1 and 2, the reaction rate doubles when the initial concentration of H2 is doubled while the initial concentration of Cl2 is held constant.

H2(g) + I2(g) ⇌ 2HI(g)

c = [HI]² / [H2][I2]

At the specified temperature, c = 53.3, hence the following can be written:

53.3 = [HI]^2 / (0.400 mol/L) × (0.400 mol/L)

or, [HI]² = 53.3 × 0.16

or, [HI]² = 8.528

or, [HI] = sqrt(8.528) mol/L

or, [HI] = 2.92 mol/L

As a result, 2.92 mol/L of HI are present at equilibrium.

Answer:

Because You never know when a meteor will hit you.

Explanation:

We have to write the electron configuration of Silicon. The atomic number of Si is 14, that means that it has 14 protons (the atomic number is equal to the number of protons of an element). Since the atom is neutrally charged, in this case it is also equal to the number of electrons.

atomic number = n° of protons = n° of electrons = 14

n° of electrons = 14

To write the electron configuration of Si we will have to arrange 14 electrons in the different sublevels. To write the electron configuration we have to place the electrons in a determined order. That order is given by the following image.

This is called the "diagonal rule", to fill the sublevels in the correct order we have to follow the arrows. We start with 1s, then 2s, 2p, 3s, 3p, 4s, 3d, 4p and so on.

In the sublevel s we can place up to 2 electrons, in the sublevel p we can place up to 6 electrons, in the sublevel p 10 electrons and in the sublevel f 14.

s ----> 2 p ----> 6 d ---> 10 p -----> 14

We start with the sublevel 1s and we place two electrons there. Then with the sublevel 2s with two more. then in the 2p we can place 6 electrons. The next one in 3s and we can place 2 electrons there. We have 1s2 2s2 2p6 3s2, we have placed 12, but we needed 14 so the last two will go to 3p. The electron configuration will be:

[Si] = 1s2 2s2 2p6 3s2 3p2

If we look at the periodic table we will see that the noble gas that is closest to Silicon is Neon. The atomic number of Ne is 10. That means that Ne has 10 protons and 10 electrons. So we can replace the first ten 10 electrons of our electron configuration by the electron configuration of Ne.

[Si] = [Ne] 3s2 3p2
