Asample of cold water was mixed with a sample of hot water inside a calorimeter, and 13,160 joules of heat energy were absorbed by the cold water. which statement is true about the hot water in the calorimeter? a. it released 26,320 joules. b. it released 13,160 joules. c. it absorbed 26,320 joules. d. it absorbed 13,160 joules.

What type of reaction is represented by the following example? 2co2 (g) + 4h2o (l) + 1452 kj 2ch3oh (l) (g) + 3o2 (g) exothermic endothermic

To save time, you can approximate the initial mass of the solid to the nearest ±1 g. for example, if you are asked to add 14.3 g of copper, add between 13 g and 15 g. which of the following sets include two samples with an equal density? which all that apply below 15.4 g gold and 18.7 g silver 15.2 g copper and 50.0 g copper 20.2 g silver and 20.2 g copper 11.2 g gold and 14.9 g gold

What produces wave a)sound b) heats c)transfer of energy d)vibrations
