3. Butane (C4H10) releases 2877 kJ per mole during a standard combustion reaction in air.

Serhud [2]

Answer:

1. The balanced thermochemical equation for the reaction is;

2C4H10 (g) + 13O2 (g) -----------> 8CO2 (g) + 10H20 (g)

2. Heat when 200g of butane is burned is 9925.65 kJ of heat

Explanation:

2 moles of butane reacts with oxygen in excess to produce carbon iv oxide and water

If 1 mole releases 2877kJ of heat

2 moles will release (2 * 2877kJ) of heat

= 5754 kJ of heat.

The mass of butane used is 200g and converting it to moles we have;

n = mass / molar mass

molar mass of butane = (12 *4 + 1 *10) = 58 g/mol

So therefore n = 200 g/ 58 g/mol

n= 3.45 moles of butane.

If 1 mole of buatne releases 2877 kJ of heat

3.45 moles will release ( 3.45 * 2877 kJ ) of heat

= 9925.65 kJ of heat

9925.65 kJ of heat is released when 200 g of butane is burned.

What is the empirical formula of a compound with a % composition of 40.1% sulfur and 59.9% oxygen?

olga_2 [115]

Answer:

The empirical formula is SO

Explanation:

The empirical formula of a chemical compound is the simplest positive integer ratio of atoms present in a compound.

Given 40.1% Sulphur and 59.9% oxygen.

We have to assume the mass of the compound to make our calculations easy.

Let's assume that the mass of the compound is 100g, that the mass of sulphur will be 40.1g and the mass of oxygen will then be 59.9g.

Number of moles= reacting mass/ molar mass

Molar mass of Sulphur = 32g/mol

Molar mass of Oxygen = 16g/mol

No of moles of S= 40.1g/100g

=0.401 moles of S

No of moles of O = 59.9g/100g

=0.599 moles of O

•These are the relative mole ratios for the compound,

•They need to be converted from decimals into whole numbers

•Turn mole ratio into whole number ratio by dividing by all the elements by the least/smallest number of moles calculated.

Number of moles of S = 0.401moles/0.401 = 1 mol S

Number of moles of O = 0.599moles/0.401 = 1.49 mol O which is approximately 1 (to the nearest whole number, considering it tenths' value which is 4 and less than 5)

The empirical formula is therefore SO.
