mixture of magnesium powder and zinc II oxide will react vigorously when heated but no reaction occurs when a mixture of Magnesium Oxide and zinc powder is heated.(i)Explain the observation made.(ii)Write the equation for the reaction between magnesium and zinc || oxide.(III)From the reaction above identify the oxidizing agen​

14 days is the half-life of phosphorus-32

what does the table look like

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.
