Identify the substance oxidized, the substance reduced, and, if any, spectator ions. Cl2 (aq) + 2KI (aq) → I2 (s) + 2KCl (aq)
Oxidation:
Reduction:
Spectator Ions:

i believe the answer is c. "baking" is the gerund, while "baking blueberry muffins" would be the gerund phrase. hope this ! : )

1. they vary with a higher number because boiling is way hotter than melting

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.
