Answer:
Option D would be correct: The mass of the products is equal to the mass of the reactants
Explanation:
For example, in chemical reactions, <u>the mass of the chemical components before the reaction is equal to the mass of the components after the reaction</u>.
hope this helps :)
3H₂ + N₂ → 2NH₃
mole of N₂ = mass ÷ molar mass
= 2.70g ÷ (14 × 2)
= 0.096 mol
mole ratio of N₂ : H₂
1 : 3
∴ if the moles of N₂ = 0.096 mol
then the mole of H₂ = 0.096 mol × 3
= 0.289 mol
Now, mass = mole × molar mass
∴ mass of H₂ needed to react = 0.289 mol × (1 × 2)
= 0.579 g
The number of mole will be 65.81 mole.
An ideal gas would be one for which both the overall volume of the molecules and even the forces that exist between them are so negligible as to have no influence on the behavior of something like the gas.
Number of ideal gas can be calculated by using the formula:
PV = nRT
where, p is pressure, n is number of mole, R is gas constant and T is temperature.
Given data:
V= 1750 = 1750 L
P = 125,000 p = 1.2 atm
R = 0.082 L /mole kelvin
T = 273+127 = 400 K
Now, put the value of given data in above equation.
1.23atm x 1750L = n x 0.0820atm x Liter/ mole x kelvin x 400K
n = 65.81 mole.
Therefore, the number of mole will be 65.81 mole
