Answer:
4.88 M
Explanation:
M = number moles/Volume (L)
MM AlCl3 = 133.34 g/mol
Volume = 500 mL = 0.5 L
number moles = mass/MM = 325.4/133.34 = 2.44 moles AlCl3
M = 2.44/0.5 = 4.88 M
Answer:
<h3>
moles of carbon dioxide=13.95mol</h3>
Explanation:
First wrie down the balance chemical reaction:
Combustion reaction: The reacion in which hydrocarbon is burnt in the presence of oxygen gas and it releases heat and this reaction exothermic because heat of cumbustion is negative.
eg. burning of methane
By using unitry method,
From the above balanced reaction it is clearly that,
from 1 mole of propane 3 moles of carbon dioxide is formed
there fore,
from 4.65 mole of propane moles of carbon dioxide will form
moles of carbon dioxide=13.95mol
NaBr (aq) + _H3PO4 (aq) → _Na3PO4(aq) + _HBr (aq)<br>
