Which type of reaction is 2c2h6 + 7o2 → 4co2 + 6h2o? a. decomposition reaction b. synthesis reaction c. combustion reaction d. double-replacement reaction

C) Combustion reaction.

Explanation: a combustion reaction is an exothermic reaction in which something reacts with oxygen. The combustion of organic compounds usually takes the form: organic compound + oxygen => water + carbon dioxide. As we can see the given reaction is an organic compound (C2H6) plus oxygen (O2) and the products are carbon dioxide (CO2) and water (H2O), so it is a combustion reaction.

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
