The answer would be 1.25g
Since you have 10g of a substance, you would need to half your substance by doing this: 42/14=3
Once doing this you would half your substance 3 times like so:
10/2=5
5/2=2.5
2.5/2=1.25
The chemical formula would be CaCO3
Answer:

Answer:
If a sample of 2 moles of nitric oxide gas was reacted with excess oxygen, 2 moles of nitrogen dioxide would be produced.
Explanation:
The balanced reaction is:
2 NO + O₂ → 2 NO₂
By stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of each compound participate in the reaction:
-
NO: 2 moles
- O₂: 1 mole
- NO₂: 2 moles
The limiting reagent is one that is consumed first in its entirety, determining the amount of product in the reaction. When the limiting reagent is finished, the chemical reaction will stop.
