A) Water (2350 g ) is heated until it just begins to boil. If the water absorbs 5.83×105 J of heat in the process, what was the initial temperature of the water?
Express your answer with the appropriate units.
B) If 125 cal of heat is applied to a 60.0-g piece of copper at 22.0 ∘C , what will the final temperature be? The specific heat of copper is 0.0920 cal/(g⋅∘C) .

A 1.250 g sample of barium chloride hydrate, BaCl2.xH2O, was
heated until all the water had been driven off. The remaining
anhydrous salt weighed 1.060g. Use this data to calculate the value
of x, the number of moles of water of crystallization in the
hydrated salt. You MUST Show ALL your work for full credit!

If 250 g of water is heated by 6 K during the experiment and the
water-mass equivalent of the coil is 2.5 g, how many calories of
energy has the water (and coil) absorbed? The specific heat
capacity (using the archaic units of calories) is: 1 cal/(g K).

A 91.70 g sample of metal was heated in a boiling water bath at
99.4 °C. The hot metal was then placed in a calorimeter, with heat
capacity 39 J/K containing 45.0 g of water. Analysis of the
thermogram showed the initial temperature to be 21.1°C, the final
temperature to be 42.3°C.
