NEED ANSWER ASAP
4.50 grams of water at 25.0 °C was heated by the addition of 133 J of energy. What was the final temperature of the water? The specific heat of water is 4.18 J/g °C Use this equation q = mc AT or AT = q/ mc AT = Tf - Ti O 109 -15.1 17.1 O 32.1 O 1.07

A 50.0 g sample of water, initially at 25.0°C, is heated until it starts to boil. How much heat was needed to heat it to 100.0°C? The specific heat capacity of water is 4.184 J/gC. ( I don't know what formula I would use to solve this.)

When 1.045 g of K2O is added to 50.0 mL of water at 25.0 ∘C in a calorimeter, the temperature of the water increases to 41.5 ∘C. Assuming that the specific heat of the solution is 4.18 J/(g⋅∘C)J/(g⋅∘C) and that the calorimeter itself absorbs a negligible amount of heat, calculate ΔHΔH in kilojoules/mol for the reaction K2O(s)+H2O(l)→2KOH(aq)K2O(s)+H2O(l)→2KOH(aq) Express the change in enthalpy in kilojoules per mole.

A piece of gold metal is heated from 25C to 90C. It is then dropped into 1 litre of water at 25.0 o C and the water temperature increases to 25.4 o C. The heat capacity of gold is 0.129 J K-1 g -1 and that of water is 4.18 J K-1 g -1. (A) what is the mass of gold sample (b) what is the entropy change in the gold as it is heated up? (c) assume that water...
