no. the gas given off is carbon dioxide. a metal with acid gives off hydrogen.
exothermic reactions-gives off heat
A reaction that gives off energy
exothermic reactions-gives off heat
An endothermic reaction is one that consumes heat.
Exothermic.
When a chemical reaction takes in more energy than it gives off, it becomes an endothermic reaction. In an endothermic reaction, energy is absorbed from the surroundings in the form of heat.
lactose + water
it gives heat off as a product
Endothermic reactions increase their enthalpy by absorbing heat
An exothermic reaction gives off heat as a result of energy being released in the form of heat. In an exothermic reaction, the products have lower energy than the reactants, leading to the release of heat to the surroundings.
alternative energy
