Answer:-
4.765 grams
Explanation:-
Molecular weight of Hydrogen gas H2 = 1 x 2 = 2 gram
Molecular weight of NH3 = 14 x 1 + 1 x 3 = 17 gram
The balanced chemical equation for the reaction is
N2 + 3 H2 --> 2 NH3
From the chemical equation we see
To produce 2 NH3 we need 3 H2 to react.
∴ To produce 2 x 17 grams of NH3 we need 3 x 2 grams of H2 to react.
To produce 27 grams of NH3 we need (3 x 2) x 27 / (2 x 17) grams of H2 to react
=4.765 grams of H2 to react
The electronic configuration of an anion is more than that from that of the corresponding neutral atom.
Answer:The number of moles will remain the same in the two cases
so we can equate using ideal gas equation which is PV =nRT
V2 = 3100 L
Explanation:
Answer:
A turbine takes the kinetic energy of a moving fluid, air in this case, and converts it to a rotary motion.
Explanation:
Answer:
2.75 g
Explanation:
The number of moles of KOH is obtained from the equation;
n=CV
C= concentration
V= volume of solution
n= 0.527 × 25.6/1000
n= 0.0135
Reaction equation;
KOH(aq) + KHC8H4O4(aq) --->(KC8H4O4)K(aq) + H2O(l)
1 mole of KHP reacts with 1 mole of KOH
Hence; 0.0135 moles of KHP reacts with 0.0135 moles of KOH
From;
Number of moles = reacting mass/molar mass
Reacting mass = 0.0135 × 204
= 2.75 g of KHP
