Answer:
c) Unchanged
Explanation:
The reaction mixture will always shift such that equilibrium is achieved !!!Even if concentration is changed , the system will move towards less stress and this is when equilibrium is achieved hence the system will always tend to proportions of reactants and products which leave the system with the least potential energy hence the equilibrium constant unchanged
The correct answer would be 2
Answer:
28g
Explanation:
Given parameters:
Number of moles of hydrogen = 3moles
Unknown:
Mass of nitrogen used = ?
Solution:
To solve this problem, let us establish the balanced reaction equation first;
N₂ + 3H₂ → 2NH₃
From the balanced reaction equation;
3 mole of H₂ will combine with 1 mole of N₂
Now,
Mass of Nitrogen = number of moles x molar mass
Molar mass of N₂ = 2(14) = 28g/mol
Mass of Nitrogen = 1 mole x 28g/mole = 28g
Atoms that share electrons in a chemical bond have covalent bonds. An oxygen molecule (O2) is a good example of a molecule with a covalent bond. Ionic bonds occur when electrons are donated from one atom to another.
