NGSS Statement from PS1.B MS :
Item Description
EC001002
Energy was transferred from the methane/oxygen system to the surroundings because the temperature of the surroundings increased.
EC002003
The methane/oxygen reaction system has more energy before the reaction occurs than after the reaction occurs.
EC006003
A scientist can use the energy from burning 1 mole of carbon (from coal) to provide the energy needed to make one mole of CaO because the reaction of one mole of C with O2 will give off more energy than is needed to produce one mole of CaO.
EC016003
The energy released by a reaction could be used for another chemical reaction, but that reaction would have to require an input of less energy.
