Answer:

Explanation:

Part A

Balancing means that the same number of elements on one side of the equation must be the same as the number of elements on the other side.

You need 3 carbons on the right side because right now there is only one. Try putting a 3 in front of the CO2 and see if the oxygens come into balance as well.

Al2(CO3)3 ⟶ Al2O3 + ___CO2

Al2(CO3)3 ⟶ Al2O3 + 3CO2

Balance check

Element                Left           Right

Al                            2                2

Carbon(C)              3                3

Oxygen                  9               3 + 6 = 9

And it is balanced.

Part B

It's a decomposition of some kind. Two smaller molecules are created from one larger one.

I think it is decomposition because it processes in which chemical species break up into simpler parts.

What is the answer to this ?
dybincka [34]
Answer:
D

Explanation:
Because the number of protons is the same as the atomic number, we know what the number of protons has to be 26. The mass number, 55, is the same as the number of protons plus neutrons. Lastly, because there is no charge on this atom, the number of electrons would have to be the same as the number of protons, which is 26.
