You have the following equations: 2S (s) + 3O 2 (g) → 2SO 3 (g), Δ H = –792 kJ
2S (s) + 2O 2 (g) → 2SO 2 (g), Δ H = –594 kJ
2SO 2 (g) + O 2 (g) → 2SO 3 (g), Δ H = ?

What is the missing ΔH?

Question options:

+198 kJ

–198 kJ

–294 kJ

+294 kJ

The  grandmother cell  is a hypothetical  neuronthat represents a complex but specific concept or object.[1]  it activates when a person "sees, hears, or otherwise sensibly discriminates"[2]  a specific entity, such as his or her grandmother. the term was in use at least as early as 1966 amongst staff and students in the department of experimental psychology, university of cambridge, england. a similar concept, that of the  gnostic neuron, was proposed two years later

No because it not possibly

1) according to the law of conservation of mass ,in all chemical reactions total mass is unchanged

Higher temperature = molecules move around faster. and vice versa.
