Hey there! Your answer is C. Increasing the volume of the container

This is because the container is already sealed, so the volume is fixed.

The pressure in a sealed container means the volume of container is fixed

so we cannot change the volume of container hence gas

The other factors which can affect the pressure are

a) moles of gas : if we increase the moles of gas the pressure of gas will increase

b) Temperature: if we increase the pressure of gas the pressure of gas will increase due to increase in kinetic energy

So the following cannot increase pressure

a) decrease in moles of gas

b) decrease in temperature of gas

2Fe + 3Cl2 → 2FeCl3 which of the following options gives the correct reactant ratio?

Mademuasel [1]

Answer: The reactant ratio in the given chemical equation will be: $Fe:Cl_2=2:3$

Explanation:

Mole ratio is defined as the ratio of the amount of moles of two substances that are participating in a chemical reaction.

In the given chemical equation:

$2Fe+3Cl_2\rightarrow 2FeCl_3$

The reactants are Fe and $Cl_2$ and the product is $FeCl_3$

The mole ratio is basically the stoichiometric ratio of the chemical compounds taking part in a chemical reaction.

The mole ratio of reactants is stoichiometric ratio of Fe and $Cl_2$ , which is:

$Fe:Cl_2=2:3$

Hence, the reactant ratio in the given chemical equation will be: $Fe:Cl_2=2:3$

The DH for the solution process when solid sodium hydroxide dissolves in water is -44.4 kJ/mol. When a 13.9-g sample of NaOH dis

salantis [7]

Answer:

The temperature increases from 23.0 C to 37.0 °C

Explanation:

Step 1: Data given

DH = -44.4 kJ/mol

mass NaOH = 13.9 grams

mass of water = 250.0 grams

Initial temperature = 23°C = 295 K

Final temperature = TO BE DETERMINED

Specific heat = 4.18 J/g*K

Step 2: Calculate change in temperature

13.9 grams/ 40 g/mol * 44.4 kJ/mol = 15429 J

15429 J = (massNaOH + mass water) * 4.18 * ΔT

15429 = 263.9 *4.18 * ΔT

ΔT = 14°C

Step 3: Calculate final temperature

ΔT= 14°C = T2 - 23°C

T2 = 23 +14 = 37 °C

The temperature increases from 23.0 C to 37.0 °C

Aluminium can not rust why .

lisabon 2012 [21]

Answer:

Aluminium Can not rust (Can't rust also meaning Corrode)

Because it's surface is protected by aluminium Oxide which stops the metal below from coming in contact with the air (which contains Oxygen) Unlike rust, which can flake off the surface of iron and steel objects, the layer of aluminium oxide does not flake off.

Corrode

destroy or damage (metal, stone, or other materials) slowly by chemical action.
