Combustion reaction because it produces water and carbon dioxide
Answer:
The correct answer is A) Concentration. See the explanation below, please.
Explanation:
We refer to concentration on the ratio between solute and solvent of a chemical solution. In the case of a more dilute solution, there is a higher proportion of solvent than solute and the opposite occurs in a concentrate.
Answer:
The mass of an atom is found in its nucleus.
Explanation:
An atom is made of three different particles: protons, neutrons and electrons.
Protons (positive charge) and neutrons (no charge) each have a mass of 1 AMU. They are both found in the nucleus (centre) of the atom.
Electrons (negative charge) are considered to have a mass of 0. Their mass is not actually 0, but very close so we do not count them. They are not in the nucleus, but found in shells surrounding the atom.
To calculate the mass of an atom, we add the number of protons and the number of electrons.
m = P + N
Answer:
I do believe it is A
