2Al + 3Cl₂ → 2AlCl₃
mol Al = 2/3 x 1.25 = 0.83
mass Al = 0.83 x 27 g/mol = 22.41 g
 
        
             
        
        
        
Answer:
Approximately  .
.
Explanation:
Look up the density  of carbon tetrachloride,
 of carbon tetrachloride,  , and glycerol:
, and glycerol:
- Density of carbon tetrachloride: approximately  . .
- Density of glycerol: approximately  . .
Let  denote the gravitational field strength. (Typically
 denote the gravitational field strength. (Typically  near the surface of the earth.) For a column of liquid with a height of
 near the surface of the earth.) For a column of liquid with a height of  , if the density of the liquid is
, if the density of the liquid is  , the pressure at the bottom of the column would be:
, the pressure at the bottom of the column would be:
 .
.
The pressure at the bottom of this carbon tetrachloride column would be:
 .
.
Rearrange the equation  for
 for  :
:
 .
.
Apply this equation to calculate the height of the liquid glycerol column:
 .
. 
 
        
             
        
        
        
I would say true because the Valence Shell Electron Pairs will Repel each other. When they do they are forced to the opposite side of the Carbon atom giving CO2 a linear molecular shape. The CO2 bond angle will be 180 degrees since it has a linear molecular geometry.

[H+][OH-]=10-¹⁴
We are using this formula because we need to find the H+
substitute the value given for hydronium ion for OH-
[H+][4.19×10⁵]=10-¹⁴
[H+]=10-¹⁴÷4.19×10⁵
[H+]=2.387×10-¹⁹
Then the pH of the solution will be
pH= –log¹⁰ [H+]
pH = –log¹⁰ [2.387×10-¹⁹]
pH= –log¹⁰2.387+19log¹⁰
 = –0.378+19
pH =18.622
