Answer:
Weathering is the breakdown of rock by natural forces and chemical changes
Explanation:
The air and water (rain) are natural forces that breaks down rocks
No, sex cells are always sex cells
Answer:
Nitrogen is inert because its p-subshell is half-filled due to it has maximum exchange energy. Thus it is exists in stable form as like inert gas and it form triple bond (N≡N). N2 molecules is very stable and its dissociation energy is 225kcal/mol.

Answer: The actual value of is -618 J/mol
Explanation:
Relation of ree energy change and equilibrium constant
where,
= Free energy change
= standard free energy change = +29 kJ/mol =
R = universal gas constant
T = temperature =
= equilibrium constant =
The actual value of is -618 J/mol
Answer:
The correct answer is 2 Na atoms
Explanation:
To determine the number of sodium atoms produced in this reaction, the reaction described in the question must be written out in an equation and then balanced
2NaN₃ ⇒ 2Na + 3N₂
From the equation above, it can be deduced that the number of sodium atoms produced in the reaction described in the question is 2
