well excuse the "s" at the end
Her adverage speed would be 160 meters per second!
If you feel the answer is incorrect please comment and I will revise! Have a good day!
Proof:
2 minutes=250 meters
6 minutes=1,250 meters
7 minutes=1,600 meters
10 minutes= 1,600 meters
Answer:
1.750×10^-6 g
Explanation:
we know n is 10^-9. all you have to do is to replace n with 10^-9.
so the answer is
1.750×10^3×10^-9 g
which is equal to 1.750×10^-6 g
if anything is unclear, ask freely.
Answer:
539.3mmHg of H₂
179.7mmHg of N₂
Explanation:
Ammonia, NH₃, reacts completely producing N₂ and H₂ thus:
2 NH₃ → N₂ + 3H₂
<em>That means there are produced 4 moles of gases and 3 are of H₂ and 1 of N₂</em>
Total pressure (Sum of pressures of N₂ and H₂) is 719mmHg. 3 parts are of H₂ and 1 of H₂
Thus, partial pressures of the products after reaction are:
719mmHg ₓ (3 H₂ / 4) = 539.3mmHg of H₂
719mmHg ₓ (1 N₂ / 4) = 179.7mmHg of N₂
