24. what is a chemical reaction?

answer: a process that involves rearrangement of the molecular or ionic structure of a substance, as opposed to a change in physical form or a nuclear reaction.

explanation:

a result in which two substances are combined

explanation:

when you put two different chemicals together they sometimes don't agree on each other or say, they don't see eye to eye so they start doing separate things to get way from each other and when this happens they cause a reaction. hope this : )

1. loamy sand is about 80% sand with 10% clay and defined mostly by sand particles with some clay to provide structure and fertility. the sand particles are easily visible and the soil holds structure but breaks apart easily.
