Please give me brainleist. :)

Answer:

2a. If the temperature is increased, the reaction will shift to the right in an attempt to release some of the heat. As the forward reaction loses heat while the reverse would create more heat.

2b. If the pressure is increased, it would shift to the left to counteract the increase in pressure as the left side will have fewer molecules.

2c. If Cl2 is added the reaction will shift to the left in order to remove the stress of the extra Cl2 and favor the production of more reactant.

2d. If PCl3 is removed, the reaction will shift to the right. When part of the equation is removed the reaction learns to adapt to the loss by trying to make more Pcl3 and counteract the effects of losing the PCl3.

3a. The reaction will shift to the right to produce more heat and counter the negative effects of losing the heat.

3b. It will shift to the left to get rid of the excess HCl being produced and form more reactant from the breakdown of the HCl.

3c. It would shift to the right in order to get rid of the excess form products from it.

3d. If pressure is decreased there will be no effect on the shift of the reaction because there is an even amount of moles of gas on each side.

4a. K=[N2O4(g0] / [NO2(g)]2

4b. (Below)

K=[N2O4(g)] / [NO2(g)]2

0.4 / 0.5(2)

0.4/0.25 = 1.6

Keq= 1.6

From the list below, determine which properties are for compounds. I. It takes a large amount of energy to separates the element
marshall27 [118]
All of them are properties of compounds except III.

for I, compounds are chemically combined together, so to separate them, we must use chemical methods like electrolysis or applying heat. These requires large amount of energy.

For II, they're always fixed. For example, in water (H2O), the ratio of hydrogen and oxygen is always 1:8 in mass. If there's some extra added, the substance becomes mixture instead of compounds.

For IV, after you chemically combined elements or compounds together, their properties are completely different. For example, iron can be attracted to magnets, but iron II sulphide does not.

Methane gas and oxygen gas react to form water vapor and carbon dioxide gas. What volume of water would be produced by this reac
yanalaym [24]

volume of H₂O = 7.2 L

Explanation:

The combustion reaction of methane (CH₄):

CH₄ + 2 O₂ → CO₂ + 2 H₂O

Now we calculate the number of moles of methane using the following formula:

number of moles = volume / 22.4 (L/mole)

number of moles of CH₄ = 3.6 / 22.4

number of moles of CH₄ = 0.16 moles

Taking in account the chemical reaction, we devise the following reasoning:

if             1 mole of CH₄ produce 2 moles of H₂O

then  0.16 moles of CH₄ produce X moles of H₂O

X = (0.16 × 2) / 1 = 0.32 moles of H₂O

And now we can calculate the volume of water (H₂O) produced by the reaction:

number of moles = volume / 22.4 (L/mole)

volume = number of moles × 22.4 (L/mole)

volume of H₂O = 0.32 × 22.4

volume of H₂O = 7.2 L

Using the information from STP or SATP conditions determine the value of the ideal gas constant.
Dovator [93]

Answer:

0.0821 atm.L/Kmol

Explanation:

At stp, the values temperature, pressure and volume is given below:

Pressure (P) = 1 atm

Temperature (T) = 273 K

Volume (V) = 22.4 L

At stp, 1 mole of a gas occupy 22.4L.

Number of mole (n) = 1 mole

Gas constant (R) =?

The ideal gas equation is given below:

PV = nRT.

With the above equation, the gas constant R can be obtained as follow:

1 atm x 22.4L = 1 mole x R x 273K

Divide both side by (1 mole x 273 K)

R = (1 atm x 22.4L) / (1 mole x 273 K)

R = 0.0821 atm.L/Kmol

Therefore, the gas constant is 0.0821 atm.L/Kmol
