Answer:
3.01×10²⁴ molecules of H₂
Explanation:
Reaction that can produce hydrogen gas from Pb can be this:
Pb + H₂S → PbS + H₂
1 mol of Pb can react to 1 mol of H₂S to produce 1 mol of PbS and 1 mol of H₂
Ratio is always 1:1.
In conclussion 5 moles of lead will produce 5 moles of H₂.
Let's apply the NA to count molecules
1 mol contains 6.02×10²³
Then, 5 moles must contain (5 . 6.02×10²³) = 3.01×10²⁴ molecules
The fumes of acetic acid go to the floor instead of ceiling.
The reason behind the answer is that the density of acetic acid fumes is higher than the density of air (almost twice) that is equal to only 1 .
Thus, the fumes of acetic acid go to the floor.
Answer:
2
Explanation:
because of the squiggly lines
C.) The pressure of the air above the substance. Hope this helps you!
Answer:
the temperature changes finally to 339k because of the increase in pressure of the gas
