What reacts with water to produce heat?

Answer 1

Combustion leads to water forming as it is typical for CO2 to be produced along with water (H2O) when burning a standard fuel such as wood. Ionic bonding does not produce water. The Bonding of two hydrogen atoms to every oxygen atom is known as covalent bonding. Ionic bonding only occurs between a non-metal and metal atoms.

Answer 2

Acids in water will produce a very exothermic reaction. It is actually unsafe to add small quantity of water to a large one of acid because the temperature of the water will rise so fast that some acid vapours could end up in your face. The best technique would be to use small amount of acid in large of water, this way, there is not going to be enough acid to raise the temperature dramatically.

Answer 3

Some metals such as sodium, potassium, and some metal oxides react violently with water to produce heat. This is because the reaction between these metals and water is exothermic, meaning it releases energy in the form of heat.

Answer 4

Exothermic reactions produce heat as a result.

An example of an exothermic reaction is the reaction of sodium with chlorine to form sodium chloride (table salt).

Answer 5

Dissolving sodium chloride in water heat is released.

Answer 6

For example reactions of alkali metals with water are very exothermic.
