Your answer would be 50 degrees Celsius. I'm almost positive.:)
The reaction is exothermic because the total bond energy of the reactants is less than the total bond energy of the products is true about change in bond in Exothermic reaction.
<h3>What is an Exothermic reaction?</h3>
An Exothermic reaction in thermodynamics is a type of reaction that released energy from the system of reaction to it's surroundings which can be inform of light, heat or even electricity or sound.
Exothermic reaction has net negative standard enthalpy change.
Therefore, The reaction is exothermic because the total bond energy of the reactants is less than the total bond energy of the products is true about change in bond in Exothermic reaction

Answer:
Correct option : B
Explanation:
First compare with
there are two lone pair in but only one lone pair presen in the so more lone pair means more repulsion and hence less bond bond angle beacuse of lone pair repulsion bonded atom come closer and hence bond angle decreased .
bond angle inversely proporional to repulsion so more repulsion means less bond angle
does no exist it exist only in the form of and here assuming because in case of difficult to compare bond angle because here two different type of bond angle is present.
there is no lone pair in the so here will no be any repulsion and hence bond will be more in as compared to
