Answer

203.7g

Explanation:

Heat gained= - heat lost

From the question

Mass of water = 360g

Heat capacity of water= 4.2Jg-1

Latent heat of ice= 334Jg-1

ml= -mcθ

m×334= -(360×4.2×(0-45))

334m= 68040

m= 68040/334

=203.7g

Which change would cause an immediate increase in the rate of the forward reaction
Studentka2010 [4]
According to Le Chatelier's Principle, to increase the rate of the forward reaction we add more of the reactants to encourage more collisions and production of more products. If it is endothermic, more heat should be added. If it is endothermic, more heat should be released from the system.
