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.

Forces and Motion:Question 1
defon

Answer:

Velocity = 12 km/h

Explanation:

Velocity can be defined as the division between distance traveled and the time it took for that distance to be traveled:

  • Velocity = Distance / Time

With the above information in mind, we can calculate the velocity of the bicycle:

  • Velocity = 18 km / 1.5 h
  • Velocity = 12 km/h

Thus the velocity of the bicycle is 12 kilometers per hour.

Why do solids expand on heating?
sdas [7]

Explanation:

The molecules of solids are shrinked in there normal state . but as a heat energy is produced , the molecules starts curating fast and fast as temperature goes up . since they vibrate , they hit and collide each other breaking the bondings this increases the surface of area of the solid , and molecules consumes that space and they expand .

the more particles a substance has at a given temperature the more thermal energy it has true or false
Flauer [41]

Answer:

\huge\boxed{\sf True}

Explanation:

Temperature and thermal energy are in a direct proportion which means that if temperature of a substance increases, its thermal energy also increases and vice versa.

Balancing Chemical Equation<br> Na+Br2=NaBr
solniwko [45]

Answer:

2Na + Br2 = 2NaBr

Explanation:

In order to balance a chemical equation you make the make sure both sides have the same number of atoms on each side, you do this by multiplying on both sides as if it was a algebraic equation.

Na+ Br2 = NaBr

Na × 2 = Na2

Na × 2 = Na2

Br × 2 = Br2

2Na + Br2 = 2NaBr

Hope this helps.
