Answer 3

question* that i posted

Answer 4

@Sheng can u plz help me in this one ?

Answer 5

my question is this

The problem says: Enthalpy is always reported with respect to a reactant. Calculate the enthalpy change, DeltaH, for each reaction in terms of kJ/mol for one of the reactants. (i.e either HCL or NaOH)

Answer 6

q = mSdeltaT

Answer 7

so do i use the individual M and volume or the total ?

Answer 8

since each equation is diff, individual

Answer 9

i mean the M and volume of the one reactant or of both reactants
