Answer:
C
Explanation:
CH₄ is the formula for methane
Answer:
17.03052 g/mol
Explanation:
Ammonia formula is given as NH3.
To estimate the molar mass of any compound, we have to add up the molar masses of every atom of the given compound. Ammonia comprises of one nitrogen atom and three hydrogen atoms.
So the molar mass of ammonia is
N: 14.0067 g/mol
H: 1.00794 g/mol
The molar mass of ammonia will thus be
14.0067 g/mol +3× 1.00794 g/mol =17.03052 g/mol
Answer:
c. The reactant that is used up before the others
Explanation:
b. is also correct, because the limiting reactant is completely used up.
a. and d. are wrong. They describe the excess reactant.
Components in a mixture don’t chemically react while compounds do chemically react and some of their original properties may be lost. A solution is when the solute mixed with the solvent.
D. A force that acts between charged and uncharged particles. I think it’s D because the electrostatic force is the attractive or repulsive force between two electrically charged objects. D is the closest answer to the definition of electrostatic force
