Question

The type of reaction in which two elements or simple compounds combine to form a single compound?

Answer 1

• The direct combination reaction or a synthesis reaction is a type of reaction in which two elements or simple compounds combine to form a single compound

• For example-$2{\mathrm{H}}_2\left(\mathrm{g}\right)+{\mathrm{O}}_2\left(\mathrm{g}\right)\to 2{\mathrm{H}}_2\mathrm{O}{\left(\mathrm{l}\right)}_{}$

hydrogen oxygen water

$2\mathrm{CO}\left(\mathrm{g}\right)+{\mathrm{O}}_2\left(\mathrm{g}\right)\to 2{\mathrm{CO}}_2\left(\mathrm{g}\right)$

carbon oxygen carbon dioxide

monoxide
