Question

Two chemical substances A and B can be touched easily by hands kept on seperate tube but when both the substances are mined in a test tube it cannot be touched due to hotness. What can be reason. behind this?​

Answer 1

The reason for this is likely an exothermic reaction, where the combination of substances A and B results in a release of heat energy.

Step-by-step explanation:

An exothermic reaction is a chemical reaction that releases heat energy. This heat can cause an increase in temperature, sometimes to a point where it becomes uncomfortable or even dangerous to touch the mixture. The exact reason why the mixture becomes hot depends on the chemical nature of substances A and B and the reaction they undergo when mixed. Some possible causes could include an increase in the rate of molecular motion as the reaction progresses, or the breaking and formation of chemical bonds, which releases energy in the form of heat. Additionally, the reaction could be releasing gases that are expanding and generating heat as a result. To determine the exact cause, a detailed analysis of the chemical composition and reaction kinetics of the mixture would be required.
