Answer:
I dont know what that is I just need points lol sorry
When sodium carbonate decomposes, it also leaves behind carbon dioxide, or CO2. You can find this out without knowing about carbonate reactions though. Chemical equations must be balanced, so whatever is on the left must also be on the right. There are 2 atoms of sodium, one atom of carbon, and three atoms of oxygon on the left. On the right, there is two atoms of sodium and one atom of oxygen. We are still missing one atom of carbon and one two atoms of oxygen, which, when combined, make a molecule of carbon dioxide.
Answer:
Yes
Explanation:
As altitude increases, the amount of gas molecules in the air decreases—the air becomes less dense than air nearer to sea level. This is what is meant by "thin air".
Are you looking for the word "enthalpy"? It's defined as the heat content of a system. We can never know the actual enthalpy of a system, only measure changes in it.
