For this problem you may find it helpful to use this calorimetry calculation template. 1
A student places 50 g of an unknown metal into a calorimeter containing 100 g of water. The initial temperature of the water is 15 °C and the initial temperature of
the metal is 237 °C. The final temperature of both is 30°C. The specific heat of water is 4.185J/g°C.

What is the ph of a solution that has a hydrogen ion concentration of 1.0 * 10 -9 m?

Which of these features are formed when hot groundwater is forced out through cracks in the earth's surface?
