Question

4. The students predict that the reaction between hydrogen and sulfur will release a lot of energy. What question could help

provide support for the prediction?

Answer 1

Let's see

`\\ \rm\rightarrowtail H_2+S=H_2S+Heat`

So

Observe the equation

it releases heat means it's exothermic

So

• Question may include+Heat
• may include ∆H=+ve
