Answer:
2.475 mol of O2 formed.
Explanation:
Given 1.65 moles of KClO3 as the target amount in the reactant, used the coefficient of the balanced chemical reaction involved to determine the number of moles of O2 molecules formed.
x mole of O2 = 1.65 mol KClO3 x [(3 mol O2)/ (2 mol KClO3)] = 2.475 mol of O2
x mole of O2 formed = 2.475 mol of O2
Answer:
1
Explanation:
I would say 1 because that configuration has 7 valence electrons. The goal of the atom is to gain a full octet so it just needs to gain 1 more electron to get the full octet. To get the one electron to fill the valence shell it would only need to have 1 covalent bond.
I hope this helps. Let me know if anything is unclear.
You'll need the specific heat capacity of aluminium to solve this question.
H=(0.005)(37-22)(specific heat capacity of aluminium)
