The rate of a reaction is dependent on the concentration of the products.

The pressure of a gas is inversely proportional to volume.

What mass of water can be heated from 25.0° C to 50.0° C by the addition of 2.825 kJ? (specific heat of water = 4.184 J/°C*g) q = mc∆T

Water always acts as an acid in reactions.

A piece of metal weighing 73.5 g is heated to a temperature of 98.7°C. The metal is then placed in 1500.0 g of water at a temperature of 25.4°C.  The temperature of the water increases to a final temperature of 28.2°C.  What is the specific heat of the metal? (specific heat of water = 4.184 J/°C *g)  qgained = -qlostq = mc∆T
