What is an alloy? how is an alloy made?

An alloy is a mixture of metals or of a metal and a non-metal. How they are made depends on the chemical properties of the components used, so it can vary. You can mix them when melted, you can mix them sometimes when they're solid and then a liquid alloy pops out, or in many different manners.

What does that mean you dum bum

Answer:

a. energy is absorbed in the reaction.

explanation:

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
