In a synthesis reaction one reactant contains 346 j of chemical energy and one reactant contains 153 j of chemical energy. the product contains 435 j of chemical energy. because energy is conserved. what energy change occurs during the reaction? a) 64 j of energy is released b) 242 j of energy is absorbed c) 64 j is absorbed d) 242 j of energy is released

Two metal blocks that have slightly different temperatures are placed next to one another. after five minutes, they both have lower but equal temperatures. according to the law of conservation of energy, what  most likelyhappened? energy was created inside the blocks.energy was destroyed inside the blocks.energy was absorbed into the blocks from outside the system.energy was transferred from the warmer block to the cooler block.
