Higher concentration of reactants equals faster rate of reaction. Reactions occur when particles collide effectively, and by increasing the concentration of reactants, you increase the number of effective collisions, thereby making the reaction occur faster.
Answer:
713mmHg
Explanation:
By using Dalton's law of partial pressure, the pressure outside the gas container is equal to the pressure inside it and this pressure equals the sum of the pressures of water and the gas.
i.e, P(total) = P(gas) + P(water)
P(gas) = P(total) - P(water)
P(gas) = 735 - 22
P(gas) = 713mmHg
A metal would be a perfect object to complete the circuit, which could be a nickel.
1 mole --------- 22.4 L at ( STP )
? moles ------- 131.97 L
131.97 x 1 / 22.4 => 5.8915 moles
Therefore:
1 mole ------------- 6.02x10²³ atoms
5.8915 moles ----- ??
5.8915 x ( 6.02x10²³) / 1 =
= 3.5448x10²⁴ atoms
hope this helps!
