Question

1. Write a balanced chemical equation for each of the following reactions. Remember that gases of elements such as oxygen are diatomic (O2). a) Methane CH4 (g) reacts with oxygen gas to produce carbon dioxide and water. _______________ b) Butane C4H10 (g) reacts with oxygen gas to produce carbon dioxide and water. ______________ c) An aqueous solution of sulfuric acid reacts with aqueous potassium hydroxide to produce potassium sulfate and water. __________

Answer 1

`CH_4_((g))+2O_2_((g))\rightarrow CO_2_((g))+2H_2O_((g))`

`2C_4H_(10)_((g))+9O_2_((g))\rightarrow 8CO_2_((g))+10H_2O_((g))`

`H_2SO_4_((aq))+2KOH_((aq))\rightarrow K_2SO_4_((aq))+2H_2O_((g))`

Step-by-step explanation:

(a)

The balanced chemical equation for the reaction of methane with oxygen gas to form carbon dioxide and water is shown below as;

`CH_4_((g))+2O_2_((g))\rightarrow CO_2_((g))+2H_2O_((g))`

(b)

The balanced chemical equation for the reaction of butane with oxygen gas to form carbon dioxide and water is shown below as;

`2C_4H_(10)_((g))+9O_2_((g))\rightarrow 8CO_2_((g))+10H_2O_((g))`

(c)

The balanced chemical equation for the reaction of solution of sulfuric acid reacts with aqueous potassium hydroxide to produce potassium sulfate and water is shown below as;

`H_2SO_4_((aq))+2KOH_((aq))\rightarrow K_2SO_4_((aq))+2H_2O_((g))`
