Question

What is thermochemical equation?Give guidelines for it​

Answer 1

Rules for Writing Thermochemical Equations:

H2O (s) —> H2O (l) ; ΔH= +6.01 kJ.

H2O (l) —> H2O (g) ; ΔH= +44 kJ.

2H2O (s) —> 2H2O (l) ; ΔH= +12.02 kJ.

3H2O (s) —> 3H2O (l) ; ΔH= +18.03 kJ.

½ H2O (s) —> ½ H2O (l) ; ΔH= +3.005kJ.

d.) ...

2H2O (l) —> 2H2O (s) ; ΔH= – 12.02 kJ Notice the – sign!

Answer 2

Answer:

A general thermochemical equation is this:

A + B → C and ΔH = (±) #

The # represents a positive or negative number (usually, not always measured in kilojoules), and A, B, and C are agents (of the chemical equation) with coefficients.
