In an acidic solution, the concentration of H+ is greater than the concentration of OH-. The pH will be less than 7.
In a basic solution, the concentration of OH- is greater than the concentration of H+. The pH will be greater than 7.
In a neutral solution, the concentration of H+ ions to OH-ions will be equal, and will therefore have a pH of 7. (This is due to water autoionization, which we usually ignore because it is small in other circumstances.)
Answer:
DECOMPOSITION
Explanation:
Examples: 2 H2O → 2 H2 + O2 CaCO3 → CaO + CO2 Decompositions are generally the opposite (reverse) of combination reactions, and they usually involve oxidation and reduction (but not in the last example).

Hello! These are the correct answers! (I took the K12 quiz)
Have a blessed day! :)
Answer:
Basis and basic are two different words.
In English, Basis is used as a noun while basic is used as an adjective. Basis term refers as the base or starting point of any discussion.
For example: Bread is a basic ingredient of cake.
On the basis of Mendel's hypothesis.
In chemistry, Basis set is used as a set of functions that represent the electronic wave function in the density-functional theory which forms an algebraic equations that can be easily implemented on a computer.
While Basic term is used for substances that can accept a hydrogen ion (H+) from another substance and have pH above 7. such as sodium.
So, It is not important that both the terms, basis and basic change their English meaning if used in chemistry, they both can be used with English meaning in chemistry as well. Bases and basic, both the terms can be used as either English or Chemistry without affecting the meaning.
