HEL PLEASEEE How should energy be represented in a chemical equation for a reaction that releases energy?
O as a reactant with a negative value
O as a reactant with a positive value
O as a product with a positive value
O as a product with a positive value

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.

give me abc and i will get it for u.
