So to stop for this, first question is what's the number of moles of silver? we have nine.
00:09
This is moles of gitsu, s.
00:13
This is silver sulfide.
00:17
And then, as per the given balance equation, three moles of silver sulfide will produce, how many moles of silver? will produce six, six moles of silver.
00:33
So that means, just cancel this, meaning it will be moles of silver since that's our unknown.
00:39
So we have 18 moles of silver.
00:45
That's our first answer.
00:47
Next question, the number of moles of silver sulfide.
00:51
If we have seven moles of aluminum, square balance equation, two moles of aluminum will react with 3 moles of silver sulfide.
01:07
So the practice you can cancel this and you'll get 10 .5.
01:13
This is moles of ag2s.
01:20
And then next question, what will be the limiting reactant? let's calculate first the mole ratio.
01:27
So mole ratio in this case will be the number of moles of the reactant divided by the coefficient of that reactant in the balance equation...
