Example Problem 5: You have 150 g of water (m). The specific heat of the water is 4.184 g/jC (c). The water starts at 70 degrees and goes up to 115 degrees. How much heat did the water absorb? (Hint: How do I find the temperature change?)

2h2s + 3o2 2so2 + 2h2o which option gives the correct mole ratios? h2s: so2 = 2: 2 and o2: h2o = 3: 2 h2s: so2 = 2: 3 and o2: h2o = 3: 2 h2s: so2 = 4: 4 and o2: h2o = 5: 4 h2s: so2 = 4: 6 and o2: h2o = 4: 4
