1. Write a balanced chemical equation for each of the following reactions. Remember that gases of elements such as oxygen are di

Anon25 [30]

Answer:

$CH_4_{(g)}+2O_2_{(g)}\rightarrow CO_2_{(g)}+2H_2O_{(g)}$

$2C_4H_{10}_{(g)}+9O_2_{(g)}\rightarrow 8CO_2_{(g)}+10H_2O_{(g)}$

$H_2SO_4_{(aq)}+2KOH_{(aq)}\rightarrow K_2SO_4_{(aq)}+2H_2O_{(g)}$

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;

$H_2SO_4_{(aq)}+2KOH_{(aq)}\rightarrow K_2SO_4_{(aq)}+2H_2O_{(g)}$
