The enthalpy of combustion of ethane gas, c2h6(g), is about -1.5*103 kj/mol. when ethane reacts with o2(g), the products are carbon dioxide co2(g) and water h2o(l). how much heat is released during the combustion of ethane gas when 14 mols of o2(g) are consumed. express your answer in kj

Which is a character of nuclear fusion but not nuclear fission

Silver tarnishes as silver metal reacts with hydrogen sulfide, h2s, in the air. in this reaction, dark silver sulfide, au2s, covers the surface of silver. when silver is polished, this coating of silver sulfide can be removed from the surface. this makes the silver shiny again. enter the coefficients that balance the tarnishing reaction equation. (type 1 for no coefficient.)

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.
