Answer:
V2 = 6616 L
Explanation:
From the question;
Initial volume = 40L
Initial Pressure, P1 = 159atm
Initial Temperature T1 = 25 + 273 = 298K (Upon converting to Kelvin unit)
Final Volume, V2 = ?
Final Pressure, P2 = 1 atm
Final Temperature T2 = 37 + 273= 310K (Upon converting to Kelvin unit)
These quantities are related by the equation;
P1V1 / T1 = P2V2 / T2
V2 = T2 * P1 * V1 / T1 * P2
V2 = 310 * 159 * 40 / (298 * 1)
V2 = 6616 L
In nature reactions of ordinary molecular hydrogen are slow since it's a diatomic molecule whose atoms are held together by very strong covalent bonds.The reaction rate of hydrogen varies depending on temperature and the properties of the reactants, for instance under high temperatures above 500°C hydrogen reacts vigorously and with fluorine it reacts explosively even under low temperatures
4.4moles of oxygen atoms
Explanation:
Given parameters:
Mass of MgSO₄ = 132.2g
Unknown:
Number of moles of oxygen atoms = ?
Solution:
The number of moles is the quantity of substance that contains the avogadro's number of particles.
To solve for this;
Number of moles = 
Molar mass of MgSO₄ = 24 + 32 + 4(16) = 120g/mole
Number of moles = 
= 1.1 moles
In
1 moles of MgSO₄ we have 4 moles of oxygen atoms
1.1 moles of MgSO₄ contains 4 x 1.1 moles = 4.4moles of oxygen atoms
