What volume of hydrogen gas is required to react with 113 liters of ethylene (C2H4) according to the following reaction? (All ga

AysviL [449]

<u>Answer:</u> The volume of hydrogen gas required for the given amount of ethylene gas is 113 L

<u>Explanation:</u>

At STP:

1 mole of a gas occupies 22.4 L of volume

We are given:

Volume of ethylene = 113 L

For the given chemical equation:

$H_2(g)+C_2H_4(g)\rightarrow C_2H_6(g)$

By Stoichiometry of the reaction:

$(1\times 22.4)L$ of ethylene reacts with $(1\times 22.4)L$ of hydrogen gas

So, 113 L of ethylene gas will react with = $\frac{(1\times 22.4)}{(1\times 22.4)}\times 113=113L$ of hydrogen gas

Hence, the volume of hydrogen gas required for the given amount of ethylene gas is 113 L

How many grams of oxygen are required to react with 12.0 grams of octane(C8H18) in the combustion of octane in gasoline?

solniwko [45]

Answer : 42 grams of oxygen are required.

Explanation :

Step 1 : Write balanced chemical equation.

The combustion reaction of octane with oxygen can be written as,

$2 C_{8}H{18} (g) + 25 O_{2} (g) \rightarrow 16 CO_{2} (g) +18 H_{2}O (g)$

Step 2 : Find moles of octane.

The given mass of octane is 12 g

Molar mass of octane is 114.2 g/mol

The moles of octane are calculated as,

$moles =\frac{grams}{MolarMass} =\frac{12g}{114.2g/mol} = 0.105 mol$

We have 0.105 mol octane.

Step 3: Use mole ratio from balanced equation to find moles of O₂

The mole ratio of octane and O₂ is 2 : 25. Let us use this as a conversion factor.

$0.105 mol C_{8}H_{18} \times\frac{25mol O_{2}}{2molC_{8}H_{18}} = 1.31 mol$

We have 1.31 mol O₂.

Step 4 : Convert moles of O₂ to grams.

The molar mass of O₂ is 32 g/mol.

The grams of O₂ can be calculated as,

$1.31 mol O_{2} \times\frac{32g}{mol} = 42 grams$

42 grams of oxygen are required.

How does entropy change with pressure?

nydimaria [60]

The entropy will increase in pressure if you increase the pressure on the system the volume decrease the energies of the particles are in a smaller space so they are less spread out
