Please help me i have no idea what this means, let alone what the answer is.
Suppose two chemicals are reacted together. It takes 600 kJ of energy to break the bonds of the reactants and 950 kJ of energy are released by the formation of the products. Which statement is true about the reaction?
Choose one answer.
a.
The reaction will give off 350 kJ of energy.

b.
The reaction is endothermic.

c.
The reaction will need an external energy source to proceed.

d.
The reaction will have a positive ∆H value

the reaction needs energy added so it is endothermic not exothermic.
It will need external energy to proceed so Bis correct.
It cannot give off energy . It needs to find an extra 150kJ to proceed.
It cannot be explosive if it cannot give off energy.
