We need to calculate the amount of chlorine gas, the mass of chlorine gas in grams that is obtained out of the decomposition of sodium chloride.
00:18
Specifically out of the decomposition of 2 .5 moles of sodium chloride.
00:27
Okay? when sodium chloride decomposes, it produces sodium, metal sodium, and the chlorine gas, okay, which is cl2.
00:45
So the first step is to balance the equation.
00:49
We have one sodium, one sodium, one chlorine, two chlorine.
00:53
We need a two here.
00:54
We unbalanced sodium, and we have to rebalance sodium by putting it through here.
01:00
Again, the question is the mass of chlorine that is produced when 2 .5 months of sodium, chloride decompose.
01:12
So these are the two substances that are involved...
