Answer:
2.94 x 
Explanation:
First we need to find out how many moles of ammonia there are, using the formula: Mass = mr x moles.
We know the mass is 83.1g, now we need to find the mR of ammonia - NH3.
N = 14, H = 1, so 14 + (3x1) = an mr of 17.
Moles = mass/ mr = 83.1/17 = 4.8882
Now we can multiply the moles by avogadro's constant to find the number of molecules:
4.8882 x (6.02 x 
) = 2.94 x molecules of ammonia
Answer:
oceans,air,rocks,soil, also living things
Explanation:
C. Condensing.
Why: Because, Condensing means to make something denser or more concentrated.
Hope this helps! ;)
Answer:
Check for a change in total mass during the reaction. During the change to a chemical reaction, the mass of the products remain equal, which results in no change of the mass. The mass will change during nuclear reactions because of the large release of energy; that results in the difference of the accumulation. ^_^
