Answer:
o and cl
Explanation:
metals and nonmetals tend to form ionic bonds
First convert volume to mass:
mass = 0.789 g/mL * 155 mL = 122.295 g
Then convert mass to number of moles:
number of moles = 122.295 g * (1 mole / 46 g) = 2.66 moles
Using avogadros number, we get the molecules:
<span>number of molecules = 2.66 moles * 6.022 x 10^23 molecules
/ mole = 1.6 x 10^24 molecules</span>
I think it’s A. The force of the stirring
Answer:
C. 101.2 L
Explanation:
N2 + H2= NH3
Balancing it,
N2 + 3 H2 = 2.NH3
(1 mol) (3 mol) (2 mol)
which means
1 molecule of nitrogen reacts with 3 molecule of hydrogen to form ammonia.
Likewise,
50.6 l of nitrogen reacts with 50.6 × 3= 151.8 l of hydrogrn to form 50.6 × 2= 101.2 l of ammonia.
Since the molar ratio of N2 to Nh3 is 2:1, you can make twice as much NH3 by using N2. Therefore, you can make a maximum of 4.5 mol of NH3 assuming 100% yield.
