Best Answer: 2 LiCl = 2 Li + Cl2 
mass Li = 56.8 mL x 0.534 g/mL=30.3 g 
moles Li = 30.3 g / 6.941 g/mol=4.37 
the ratio between Li and LiCl is 2 : 2 ( or 1 : 1) 
moles LiCl required = 4.37 
mass LiCl = 4.37 mol x 42.394 g/mol=185.3 g 
Cu + 2 AgNO3 = Cu/NO3)2 + 2 Ag 
the ratio between Cu and AgNO3 is 1 : 2 
moles AgNO3 required = 4.2 x 2 = 8.4 : but we have only 6.3 moles of AgNO3 so AgNO3 is the limiting reactant 
moles Cu reacted = 6.3 / 2 = 3.15 
moles Cu in excess = 4.2 - 3.15 =1.05 
N2 + 3 H2 = 2 NH3 
moles N2 = 42.5 g / 28.0134 g/mol=1.52 
the ratio between N2 and H2 is 1 : 3 
moles H2 required = 1.52 x 3 =4.56 
actual moles H2 = 10.1 g / 2.016 g/mol= 5.00 so H2 is in excess and N2 is the limiting reactant 
moles NH3 = 1.52 x 2 = 3.04 
mass NH3 = 3.04 x 17.0337 g/mol=51.8 g 
moles H2 in excess = 5.00 - 4.56 =0.44 
mass H2 in excess = 0.44 mol x 2.016 g/mol=0.887 g
        
             
        
        
        
Im sorry but this is not a quotient problem but an addition one, I can still simplyfy it for you though.

Answer:
Strong Negative 
Step-by-step explanation:
We already know that the answer is between c and d because the correlation coefficient negative. 
We just have to figure out whether it is strong or weak. 
In general, anything between -.7 and -1 is considered to have a strong correlation. -.8 is in between -.7 and -1 therefore the correlation is best described as strong negative. 
 
        
             
        
        
        
The answer is D
Hope this helps
