1 mole ----------- 6.02x10²³ molecules
? moles ---------- 3.4x10²³ molecules
(3.4x10²³) x 1 / 6.02x10²³ =
3.4x10²³ / 6.02x10²³ => 0.564 moles of H2SO4
Answer: the answer is that you made $2
Explanation:
Air is a mixture of several gasses
Answer: a
Explanation: hope it helps
Answer:
C- Using a 0.35 g sample of Li(s) cut into smaller pieces will increase the rate of reaction
C- Equal quantities of gas will be produced with potassium K, used instead of Lithium, Li.
Explanation:
<u>First part</u>
When a metal is present in small pieces, the rate of the chemical reaction increases. This is due to small pieces provide more surface area for reaction than huge chunks of Li.
moles of reactant decreases product formation rate also decreases and temperature decreases rate also decreases so remaining option are wrong
<u>Second part
</u>
2Li + 2H2O --------------> 2LiOH + H2
2K + 2H2O ---------------> 2KOH + H2
Hence, both gives same quantity of gas
