Question

The following sentences describe chemical reactions. For each one, enter the skeletal structure of the reaction in the text box. Balance it, and add the state symbols.1. When iron(III) oxide (red rust) reacts with carbon monoxide gas, metal iron and carbon dioxide gas are produced.2. When aqueous cobalt(III) chloride is added to aqueous sodium hydroxide, solid cobalt(lll) hydroxide is formed as well as aqueous sodium chloride.

Answer 1

1.

The chemical reaction is written as follows:

$Fe_2O_3(s)+3CO(g)\rightarrow2Fe(s)+3CO_2(g)$

2.

The chemical reaction is written as follows:

$\text{CoCl}_3(l)+3NaOH(l)\rightarrow Co(OH)_3(s)+3\text{NaCl(l)}$

Thus, the balanced chemical equation with their state is written as above.
