Endothermic or exothermic?

The reaction between ammonium nitrate and water absorbs heat from the surrounding environment.
Three drops of concentrated sulfuric acid added to 100 milliliters of water in a beaker makes the beaker hot.
Ammonium chloride dissolved in a beaker of water makes the beaker cold.
Uranium atoms are split to produce nuclear energy.
Water separates into hydrogen and oxygen when an electric current is run through it.
Methane and oxygen are combined to produce methanol and heat.

Endothermic reactions:

The reaction between

ammonium nitrate and

water absorbs heat

from the surrounding

environment.

Ammonium chloride dissolved

in a beaker of water makes the

beaker cold.

Water separates into

hydrogen and oxygen

when an electric current

is run through it.

Exothermic reactions:

Three drops of concentrated

sulfuric acid added to 100

milliliters of water in a beaker

makes the beaker hot.

Uranium atoms are split to

produce nuclear energy.

Methane and oxygen are

combined to produce

methanol and heat.
