Answer: 4.5 moles of  can be made from complete reaction of 3.0 moles of Al.
 can be made from complete reaction of 3.0 moles of Al.
Explanation:
The given reaction equation is as follows.

This shows that 2 moles of Al reacts with 6 moles of HCl. So, the amount of HCl required to react with 1 mole Al is three times the amount of HCl.
Therefore, 3 moles of Al will react with 9 moles of HCl to give 3 moles of  and
 and  moles of
 moles of  .
.
The reaction equation now will be as follows.

The moles  can also be written as 4.5 moles.
 can also be written as 4.5 moles.
Thus, we can conclude that 4.5 moles of  can be made from complete reaction of 3.0 moles of Al.
 can be made from complete reaction of 3.0 moles of Al.

A homogenous mixture is uniform and thus hard to recognize as a mixture. An example is water.
        
             
        
        
        
Answer:
D. C > B >A
Hope it helps!
Explanation:
From strongest to weakest, the intermolecular forces rank in the following way:
Strongest: Hydrogen bonding. This occurs when compounds contain #"O"-"H"# , #"N"-"H"# , or #"F"-"H"# bonds. ...
Less strong: Dipole-dipole forces. ...
Weakest: London Dispersion Forces.
 
        
                    
             
        
        
        
Answer:
The molar mass of a compound is The mass in grams of 1 mole of the compound (Option A) 
Explanation:
Let's take ammonia as an example (NH3)
Mass of N = 14 g
Mass of H = 1 g
Molar mass of ammonia is Mass of N + (Mass of H).3
14 + 3 = 17 g/m
Ammonia is a compound that has 1 mol of N, plus 3 moles of H (see the formula)
The number of atoms in 1 mole of the compound --> This is Avogadro
