Mole fraction is a unit of concentration, defined to be equal to the number of moles of a component divided by the total number of moles of a solution. Because it is a ratio, mole fraction is a unitless expression. The mole fraction of all components of a solution, when added together, will equal 1.
1. Given the following equation: N2 (g) + 3 H2 (g) ↔ 2NH3 (g) ΔH = -92 kJ/mol
a. this reaction is exothermic as ΔH is -ve
b. the equilibrium will shift 2 the left if nitrogen gas is removed
c. the equilibrium shift 2 the right if the temperature is lowered
d. the equilibrium shift 2 the left if ammonia (NH3) is added
e. principle of thermodynamic potential or Gibbs energy is used to answer B-D
Explanation:
it is used to describe those action of adrenal corticosteroids that produce sodium
Answer:
2. +7
Explanation:
The oxidation state of Cl in `HClO_(4)` is +7.Apr 17, 2022
3ans. CrS+2No3 --) 2No+So4+cr^3+
Cr=1 Cr=1
S=1 S=1
N=1=2 N=1=2
O=3=6 o=5=6
now that is how it look and it is not balanced in oxygen so add 2 in the front of No3.
it will look something like this 2NO3. even if u add 2 in the fornt it is not balance so add again 2 in the No in second and it will look like this 2NO.
so now it is blance.
