Answer: Explanation:
When supply and demand for a product increase simultaneously, we cannot predict the market clearing price, but know that the equilibrium quantity will increase.
NB: We cannot predict the market clearing price because no adequate information such as government policy is provided. such information would likely affect the market clearing price either positively or negatively.
P.S: This is a business question.
b) LiH (s) + H₂O (l) --> LiOH (aq) + H₂ (g)
When an alkali metal reacts with water it always produces the metal hydroxide and hydrogen gas which is liberated into the air.
2M(s)+2H₂O (l) →2MOH (aq)+ H₂ (g)
Lithium reacts with water very vigorously.
Alkali metals need to be stored under oil to prevent them from reacting with the oxygen and water vapour in the air. The reactivity of the alkali metals increases down the group.
Alkali metals consist of the following metals:
Lithium, sodium, potassium, rubidium, caesium.
Lithium, sodium and potassium also react vigorously with water and produce hydrogen gas and which is liberated in the air.

Answer:
The molecules of the liquid collide with the molecules of solid, gradually breaking the bonds between the molecules in the solid and causing the ice to melt.
