Explain the difference between mass and weight. Why is your weight on the Moon one-sixth that on Earth?
1 answer:
The weight on moon is of the weight at earth because the value of g reduces to
on moon.
Mass is a measure of the amount of matter in an object, and Weight is the amount of force that gravity exerts on an object.
What is the relation between mass and weight?
- The main difference between mass and weight is: Mass is a scientific measure of the amount of matter an object is made of. Regardless of where you are at any given moment, the mass is constant.
- However, weight is actually a description of gravity on an object.
- The relation between mass (m) and weight (W) is
. Thus, weight is defined as the product of mass and gravitational acceleration (g)
- As weight depends on the value of gravitational acceleration, it changes as the value of g changes.
- Now, the value of g at moon is
of the value of g at earth, that means the weight on moon is

Answer : The correct expression for equilibrium constant will be:
Explanation :
Equilibrium constant : It is defined as the equilibrium constant. It is defined as the ratio of concentration of products to the concentration of reactants.
The equilibrium expression for the reaction is determined by multiplying the concentrations of products and divided by the concentrations of the reactants and each concentration is raised to the power that is equal to the coefficient in the balanced reaction.
As we know that the concentrations of pure solids and liquids are constant that is they do not change. Thus, they are not included in the equilibrium expression.
The given equilibrium reaction is,
The expression of will be,
Therefore, the correct expression for equilibrium constant will be,
