Ammonia, NH3, is a typical ingredient in household cleaners. It is produced through a combination reaction involving N2(g) and H
GalinKa [24]
The balanced chemical reaction is:

N2 + 3H2 = 2NH3

We are given the amount of hydrogen gas to be used in the reaction. This will be the starting point of the calculations.

24.0 mol H2 (2 mol NH3 / 3 mol H2 ) = 16 mol NH3

Therefore, ammonia produced from the reaction given is 16 moles.

A pharmacist wishes to strengthen a mixture from 10%alcohol to 30% alcohol. How much pure alcohol should be added to 7 liters of
Tomtit [17]

Answer:

2 litres of pure alcohol will be added to make the overall concentration of 9 litres of mixture as 30%.

Explanation:

Suppose x is the number of litres added to the 10% mixture than the quantity of new mixture is given as below

  • n_{old}=7 litres
  • n_{new}=7+x litres

Also the quantity of alcohol is given as

  • q_{old}=10 \% \, of \, 7 \, litres =0.7
  • q_{added}=x
  • q_{new}= 30 \% \,of \,new\, quantity = 0.3(7+x)

Now the equation is as

                                  q_{old}+q_{added}=q_{new}\\0.7+x=0.3(7+x)\\0.7+x=2.1+0.3x\\x-0.3x=2.1-0.7\\0.7x=1.4\\x=2 \, litres

So 2 litres of pure alcohol will be added to make the overall concentration of 9 litres of mixture as 30%.

How many oxygen atoms are contained in 2.74 g of Al2(SO4)3?
abruzzese [7]

Answer:

5.79 × 10^23 Oxygen atoms

Explanation:

Number of Oxygen atom in the compound = 4×3 = 12

Molar mass of Al2(SO4)3 = 342 g/mol.

No of mole = mass/molar mass = 2.74/342 = 8.01×10^-03 mole

2.74g of Al2(SO4)3 × 1 mole of Al2 (SO4)3 / 342g of Al2 (SO4)3 * 12 mole of Oxygen/ 1mole of Al(SO4)3 * 6.02×10^23 Oxygen atom/ 1 mole of Oxygen

= 5.79×10^23 Oxygen atoms
