Some titanium having a mass of 73.67 g was heated to 100.0 °C and then put it into 100.0 mL of water (initially at 20.5 °C). If the specific heat of
titanium = 0.523 J/g.°C, calculate the equilibrium temperature (Assuming
no heat lost to the environment). *

The combustion of methane, ch4, releases 890.4kj/mol. that is, when one mole of methane is burned,890.4 kj are given off to the surroundings. this meansthat the products have 890.4 kj less than the reactants.thus, ah for the reaction = - 890.4 kj. a negative symbolforah indicates an exothermic reaction.ch (g) + 20 (g)> co2 (g) + 2 h0 (1); ah = - 890.4 kga) how much energy is given off when 2.00 mol of ch,are burned? b) how much energy is released when 22.4g of ch. areburned?
