Answer:
you have multiply the produced moles of AgCI,Which is 0.012moles with the molar mass of AgCI,Which is 143.32g/mol.In doing so the answer will be 1.72gAgCI.

Answer: –2,840 kJ/mol
Explanation:
Heat of combustion is the heat produced when 1 mole of the substance is completely oxidized. The production of heat means the reaction is an exothermic process and gives off energy.
According to the given balanced chemical equation:
1 mole of glucose is being completely oxidized to give carbon dioxide and water and thus heat of combustion is -2840 kJ/mol.
Atomic mass!!! the electrons and atomic mass will always be the same most the time
Since X is 1 g, therefore O must be 0.1 g. Therefore:
moles O = 0.1 g / (16 g / mol) = 0.00625 mol
We can see that for every 3 moles of O, there are 2 moles
of X, therefore:
moles X = 0.00625 mol O (3 moles X / 2 moles O) =
0.009375 mol
Molar mass X = 1 g / 0.009375 mol
<span>Molar mass X = 106.67 g/mol</span>
If you keep an egg in salt for too long.....it might form a stronger shell because salt helps fill up the cracks....but I have no idea. =\
