Chemistry help PLEASE!! A solution of hydrazine (N2H4) was standardized by titration with sodium bromated (NaBrO3). It required 25.62 mL of hydrazine solution to react completely with 3.8101 grams of sodium bromated. The unbalanced reaction is: N2H4(l) + BrO3^- (aq) —> Br^- (aq) + N2(g)
a) balance the equation
b) calculate the molarity of the hydrazine solution
c) how many grams of N2 are produced?

the dissolution of polymer can be thermodynamically described in 2 steps.

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.
