It could be both A. and B. but most likely B. because the star can b big but have the same temperature as a smaller star.

The l</span>ewis structure of the hypochlorite ion is attached below. From the lewis structure, it can be seen that, in hypochlorite ion Cl and O shares one pair of electrons. Hence, bond order of<span> hypochlorite ion is one. </span>
<u>Answer:</u> The amount of heat released for 5.25 moles of hydrogen peroxide decomposed is 1032.15 kJ
<u>Explanation:</u>
We are given:
Heat released in the reaction = 196.6 kJ per mole of hydrogen peroxide
Heat released for 2 moles of hydrogen peroxide decomposed =
<u>Sign convention of heat:</u>
When heat is absorbed, the sign of heat is taken to be positive and when heat is released, the sign of heat is taken to be negative.
The chemical equation for the decomposition of hydrogen peroxide follows:
We are given:
Moles of hydrogen peroxide decomposed = 5.25 moles
By Stoichiometry of the reaction:
2 moles of hydrogen peroxide decomposed, the amount of heat released is 393.2 kJ
So, when 5.25 moles of hydrogen peroxide decomposed, the amount of heat released will be =
Hence, the amount of heat released for 5.25 moles of hydrogen peroxide decomposed is 1032.15 kJ
