The volume of 4.92 grams of hydrogen gas at STP is 55 L.
<u>Explanation</u>:
1 mole of an ideal gas will occupy 22.4 L
To find volume, the molar volume of a gas is
22.4 L / 1 mole H
2 → this takes you from moles of H
2 to liters
Now, to find the number of moles present in 4.92 g of hydrogen gas, you can use the gas' molar mass
4.92 g 1 mole H
2 / 2.016
g = 2.44 moles H
2
This sample of hydrogen gas will thus occupy
2.44 moles H
2 22.4 L / 1 mole H
2 = 54.6 L = 55 L.
Increase the Surface Area of the Reactants. Increasing the surface area of the reactants increases the rate of the reaction. More surface area means more collisions of the reactant molecules and an increased rate of the reaction. This occurs when reactants are made to react in powdered form
Answer:
