S 2 O 8 ^ 2- (aq)+3 I^ - (aq) 2 SO 4 ^ 2- (aq)+I 3 ^ - (aq) In , the reaction represented by the balanced equation shown above the experimentaily determined rate law rate=k[S 2 O 8 ^ 2- ][I^ - ] the concentration of doubled keeping I constant of the following experimental results is predicted based on the rate law, and why?

c is the answer because when something is left after something evaporates that shows the chemical change.

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.

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.
