Question

The reaction of coal and water at a high temperature produces a mixture of hydrogen and carbon monoxide gases. This mixture is known as Synthesis gas (or syngas). What mass of carbon monoxide can be formed from the reaction of 71.3 g of carbon with excess water?
C(s) +H2O H2(g) + CO(g)

Answer 1

Solution :-

Balanced reaction equation

C(s) + H2O(l) --- > H2(g) + CO(g)

Using the given mass of carbon we can find the mass of                carbon monoxide that can be formed by using the stoichiometric mole ratio of the C and CO.

Lets set up the equation and calculate the mass of CO that can be formed using the 71.3 g Carbon

(71.3 g C * 1 mol / 12.01 g)*(1 mol CO / 1 mol C)*(28.01 g / 1 mol CO) = 166 g CO

Therefore the mass of the carbon monoxide (CO) that can be formed is 166 g CO
