Answer 2

Chemical Reactions and Types

a) The chemical equation for the reaction between magnesium carbonate (MgCO3) and heat to form magnesium oxide (MgO) and carbon dioxide (CO2) can be written as:

MgCO3 → MgO + CO2

This reaction is an example of a decomposition reaction, where a single compound breaks down into two or more simpler substances. [[1]]

b) The chemical equation for the reaction between aluminum (Al) and sulfur (S) to form aluminum sulfide (Al2S3) can be written as:

2 Al + 3 S → Al2S3

This reaction is an example of a combination reaction, where two or more substances combine to form a single compound. [[2]]

Additional Reactions and Types

a) The chemical equation for the reaction between aluminum (Al) and oxygen (O2) can be written as:

4 Al + 3 O2 → 2 Al2O3

This reaction is an example of a combustion reaction, where a substance reacts with oxygen to produce heat and light. [[3]]

г) The chemical equation for the reaction between copper hydroxide (Cu(OH)2) and heat to form copper oxide (CuO) can be written as:

Cu(OH)2 → CuO + H2O

This reaction is an example of a decomposition reaction, where a single compound breaks down into two or more simpler substances. [[4]]
