'Exothermically' refers to a process or reaction that releases energy in the form of heat to its surroundings. It is the opposite of an endothermic process, which absorbs heat from the surroundings.

What type of substance will react exothermically wit oxygen?
Substances that react exothermically with oxygen include fuels like gasoline, natural gas, and wood. During combustion, these substances release heat and energy as the oxygen in the air supports the chemical reaction.
What temp does ammonia dissolve in water?
Ammonia dissolves in water exothermically, with the solubility increasing as the temperature decreases. At room temperature (25°C), ammonia has a solubility of about 32.5 g/L in water.
Was the reaction aluminum oxide underwent in the Hindenburg endothermic or exothermic?
The reaction that aluminum oxide underwent in the Hindenburg was exothermic. Aluminum oxide reacted exothermically with iron oxide to generate aluminum and iron, releasing heat in the process.
when potassium is added to water what causes explosion?
When potassium is added to water, it reacts exothermically with the water to produce potassium hydroxide and hydrogen gas. The rapid production of hydrogen gas in the reaction causes an explosion due to the build-up of pressure from the gas release.
Are nitric acid and ammonia compatible?
Nitric acid and ammonia are not compatible because they can react exothermically to form ammonium nitrate, which is a highly explosive compound. Mixing these two chemicals can be dangerous and should be avoided.
Why is calcium oxide described as a base?
It reacts with acids, it dissolves exothermically in water to produce a basic solution.
What type of substance will react exothermically wit oxygen?
Substances that react exothermically with oxygen include fuels like gasoline, natural gas, and wood. During combustion, these substances release heat and energy as the oxygen in the air supports the chemical reaction.
Which compound forms exothermically?
An exothermic reaction releases heat energy to the surroundings. Compounds like combustion reactions (e.g. burning of wood or gasoline) typically release heat during their reaction, making them exothermic.
What type of energy does a fire use?
Chemical potential energy. Fire is a chemical reaction caused by heat Fuel and oxygen (usually) The fuel is combusted exothermically (ie giving off heat) with oxygen which is a chemical reaction. This causes surrounding fuel to heat up a react exothermically with the oxygen, propagating the fire.
What temp does ammonia dissolve in water?
Ammonia dissolves in water exothermically, with the solubility increasing as the temperature decreases. At room temperature (25°C), ammonia has a solubility of about 32.5 g/L in water.
What dissolves exothermically?
Salt dissolves exothermically in water, releasing heat. This is due to the energy released when strong ionic bonds in the salt break and new bonds are formed with water molecules. Other substances that can dissolve exothermically include calcium chloride and potassium hydroxide.
Does sugar decrease the temperature of hot boiling water?
yes. sugar doesn't react exothermically with water (it doesn't give out heat when you put it in water). It will usually absorb some of the heat from the water for thermal equilibrium to occur.
Where does the energy from a firework come from?
The energy in a firework comes from the combustion of the explosive chemicals inside it. When ignited, these chemicals react exothermically, releasing energy in the form of heat and light, which creates the dazzling visual display we see in the sky.
Was the reaction aluminum oxide underwent in the Hindenburg endothermic or exothermic?
The reaction that aluminum oxide underwent in the Hindenburg was exothermic. Aluminum oxide reacted exothermically with iron oxide to generate aluminum and iron, releasing heat in the process.

When potassium is added to water, it reacts exothermically with the water to produce potassium hydroxide and hydrogen gas. The rapid production of hydrogen gas in the reaction causes an explosion due to the build-up of pressure from the gas release.
Are nitric acid and ammonia compatible?
Nitric acid and ammonia are not compatible because they can react exothermically to form ammonium nitrate, which is a highly explosive compound. Mixing these two chemicals can be dangerous and should be avoided.
Which chemical is called plaster pf paries?
CaSO4 1/2 H2O. Calcium sulfate hemihydrate. This reacts exothermically, i.e gives off heat, when it reacts with water to form CaSO4 2 H2O, Calcium sulfate dihyrate also known as gypum, a white solid.
