The balanced combustion reaction for CH is 2CH.1) + 1502(g) → 12 CO2(g) + 6 H, O(1) + 6542 kJ
If 6.900 g C H is burned and the heat produced from the burning is added to 5691 g of water at 21 °C, what is the final
temperature of the water?

The characteristics of two different types of reactions are shown below: reaction a: electrons are gained by the atoms of an element. reaction b: protons are lost by the atom of an element. which statement is true about the atoms of the elements that participate in the two reactions? their identity changes in both reaction a and reaction b. their identity changes in reaction a but not in reaction b. their identity changes in reaction b but not in reaction a. their identity remains the same in both reaction a and reaction b.
