It is a subscript
Also do you mean Cl not Ci. I assume you do because then it means 4 chlorine in that compound.
Moles Li = 3.50 g / 6.941 g/mol= 0.504
the ratio between Li and N2 is 6 : 1
moles N2 required = 0.504 /6=0.0840
we have 3.50 g / 28.0134 g/mol=0.125 moles of N2 so N2 is in excess
the ratio between Li and Li3N is 6 : 2
moles Li3N = 0.504 x 2 /6=0.168
mass Li3N = 0.168 mol x 34.8297 g/mol=5.85 g
Answer:
b. a new gas is observed in the form of bubbles
Explanation:
The only statement that was evidence of a chemical reaction is a new gas is observed in the form of bubbles Any time a new substance is created, a chemical reaction has taken place.
The distance from one point to another is the distance traveled by a light beam between them.
If you have the coordinates of the 2 points, then the distance between them is
√ of [ (the difference in their x-values)² + (the difference in their y-values)² ]
