Answer:
3 moles of hydrogen, , are needed to react completely with 1 moles of nitrogen,
Explanation:
Let us consider the Reaction of Nitrogen and hydrogen
Two nitrogen atom reacts with 3 hydrogen atom to form ammonia. So it is clear from the chemical equation that 3 moles of hydrogen atom is essential to react completely with nitrogen.
Also when we see the atomic structure of hydrogen and nitrogen ,Hydrogen has only one electron its shell and nitrogen has 5 electron in its valency shell. so for an Nitrogen to have a completely filled shell, it needs 3 more electrons .Thus is need 3 hydrogen atom
Answer:
97.994 g/mol
Explanation:
One molecule of H₃PO₄ contains three atoms of H, one of P, and four of O.
3H = 3 × 1.0079 u = 3.0237 u
1P = 1 × 30.974 u = 30.974 u
4O = 4 × 15.999 u = <u>63.996 u
</u>
Total = 97.994 u
One molecule has a mass of 97.994 u.
One mole has a mass of 97.994 g.
The molar mass of H₃PO₄ is 97.994 g/mol.
Gas particles are in constant motion and are very far apart compared to their size.

Answer:
Equilibrium concentration of reactants and products:
Explanation:
The equilibrium constant of the reaction =
Mole sof HI = 0.372 mol
Volume of the vessel = 1.00 L
Initial concentration of HI =
0.372 M
At equilibrium
(0.372-2x) M x x
An expression of an equilibrium constant will be given as;
Solving for x;
x = 0.03935
Equilibrium concentration of reactants and products:
