What is the name for a substance formed in a chemical reaction? a_reactant b_catalyst c_enzyme d_product

Hello there, and thank you for asking your question here on

Reactant. Chemical reactions are usually affected by a chemical change, and they stop one or more other things, which often have properties different from the other reactants.

Hope this helped you! ♥

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant.
