Chemours hikes Titanium Dioxide price

SOLVED: Question 11: The combustion of titanium with oxygen produces titanium dioxide: Ti(s) O2(g) -> TiO2(s)In some parallel universe, when 0.854 g of titanium is combusted in a bomb calorimeter, the temperature of the calorimeter increases from 21.09 °C to 46.94 °C. The calorimeter contains 920.566 g of water and the bomb's heat capacity is 8.99 kJ/°C. For this parallel universe, what is the energy change for the reaction per mole of Ti combusted? (mol Ti)

SOLVED: The mass percent of titanium dioxide (TiO2) in an ore can be evaluated by carrying out the following reaction and measuring the amount of O2 gas produced.3TiO2 (s) 4BrF3 (l) = 3TiF4 (s) 2Br2 (l) 3O2 (g)If 2.376g of a TiO2-containing ore generates 0.143g of O2, what is the mass percent of TiO2 in the ore sample?
