In the laboratory a student burns a 0.421-g sample of azulene (C10H8) in a bomb calorimeter containing 1170. g of water. The temperature increases from 24.30 °C to 27.30 °C. The heat capacity of water is 4.184 J g-1°C-1. The molar heat of combustion is −5291 kJ per mole of azulene. C10H8(s) + 12 O2(g) 10 CO2(g) + 4 H2O(l) + Energy Calculate the heat capacity of the calorimeter.

Which statements are true concerning mineral formation? check all that apply. the slower the cooling, the larger the crystals. the faster the cooling, the smaller the crystals. crystals formed from magma are smaller than crystals formed from lava. minerals can only form in solutions when the solution is heated deep underground. when a solution cools, elements and compounds leave the solution and crystallize as minerals. minerals formed from hot water solutions can form narrow channels in the surrounding rock.

The three types is stress that act on earths rocks are compression, tension, and
