Is burning gasoline an exothermic process or an endothermic process?
Solid to gas (sublimation) is endothermic (takes in heat).In other words:A phase change from the solid state to the gas state is endothermic.Sublimation is endothermic (takes in energy).Heat energy must be provided to make it work.When there is a change of state from a solid to a liquid, a solid to a gas, or a liquid to a gas, at a constant temperature, the process is endothermic NOT exothermic. It requires energy to break the intermolecular forces that keep the molecules together, and that reduces the temperature - heat is taken in.
Is vaporization is a exothermic or endothermic?
Yes, vaporization is an endothermic reaction while freezing is an exothermic reaction. Think of a pot of water set of the stove. What are you doing to it? You're putting in heat in order to break the hydrogen bonds. The heat/energy is being expendedor absorbed to make the water boil. In the case of freezing (say water), the hydrogen bonds are realigning while producing heat.
Is drain cleaner endothermic or exothermic?
Drain cleaner is typically exothermic. When it is mixed with water, it produces heat as a result of an exothermic chemical reaction. This heat helps to dissolve and remove the clogs in the drain.
Is boiling an egg endothermic or exothermic?
It is endothermic as the water mus gain energy to go from a liquid to a gas.
When oil is burned is it endothermic?
Fire creates an exothermic reaction, not endothermic. To be endothermic, the reaction must draw in heat from its surroundings, thereby making things colder.
Is an explosion of hydrogen gas when it reacts with oxygen gas endothermic or exothermic?
Exothermic , since when they react, they form a bond. All bonds that are formed release potential energy , and any exothermic reaction involves a loss of energy.
Is the dissolving of calcium chloride endothermic or exothermic?
Both beacuse in such coditions it can be endothermic or exothermic.
When Natural gas is burned in a furnace is it endothermic or exothermic?
exothermic
What happened when the lye dissolve in the water in terms of energy?
Exothermic reaction, then explosion from hydrogen Gas production.
Is obtaining lime from limestone exothermic?
The hydratation of concentrated OH- and Na+ ions (by dilution) is exothermic, it gives an energetically prefered state of matter.(Hydratation is the extra surrounding of the ions by polar water molecules of the solvent).
Is liquid to a gas endothermic or exothermic?
It is exothermic. The gas must release energy to its surrounding to become a liquid.
Is ammonia solution and water an exothermic or endothermic reaction?
Gas devolve reactions are exothermic. So it is a exothermic too.
Is a liquid endothermic or exothemic?
A liquid on its own cannot be described as either endothermic or exothermic. The terms endothermic and exothermic are the names of two opposite process reactions. An endothermic reaction absorbs heat and and exothermic reaction gives off heat. A liquid can be involved in either an endothermic reaction or in an exothermic reaction. If you are evaporating a liquid from its liquid phase to its gas phase, then the reaction is usually endothermic and vice versa, going from the gas phase to the liquid phase, the reaction is usually exothermic.

Classify the burning of natural gasses in exothermic or endothermic changes?
The burning of natural gas is an exothermic process.
The following is exothermic or endothermic"The combustion of gasoline in a car engine?
Gas
Is baking soda and vinegar an endothermic or exothermic reaction?
This is a chemical change because once the substances are put together to form a gas it cannot be changed.
