Answer:The major difference between atomic number and mass number is that the atomic number states the number of protons present in an atom whereas, the mass number indicates the total of the number of protons and the number neutrons present in an atom.i) Atomic number is the total number of protons present in the nucleus of an atom. It is also equal to the number of electrons for a neutral atom. Example, atomic number of sodium is 11. ii) Mass number is the number of protons and neutrons in the nucleus taken together. For example, mass number of sodium is 23 g/mol.

Which stattement best describes beaches
KiRa [710]

Hello there!

I do not know what the statements are but i will explain some characteristics of the beach to you!

Beaches are made of sand, they are along the coast, the coast is when a state (such as California) is along the beach, or the ocean, beaches also sometimes have trees, but usually when the ocean rises the ocean takes the tree into its depths. That's why sometimes you see tree trunks on the beach, but be careful sometimes if you sit on them they will cave in because of all the salt it absorved from the oceans water, sometimes you will see seagulls, seagulls like to eat the fish from the ocean, and/or the crabs that wash up on shore.

I hope this helped you!

Good luck!

C

From reading what the process is, I think the answer should be C. The definition always says that you get energy from a chemical reaction and the products are CO2 and water. That can only mean that you have a hydrocarbon burning.

Chemically it looks like

C6H12O6  +  6O2 ====> 6CO2 + 6H20
