How do you separate a mixture of sodium chloride and potassium trioxonitrateV

See explanation

Explanation:

We separate substances based on their important properties such as reaction to heat, solubility in water, magnetic properties, etc.

To separate sodium chloride and potassium trioxonitrateV, we need to heat the solution. KNO3 dissolves at a high temperature and crystallizes out as the solution is cooled.

Hence when we heat the solution, KNO3 dissolves, as we cool the solution, solid KNO3 crystals are obtained while NaCl remains in solution.  We have now separated the two salts in the solution.

Note that the solubility of NaCl is almost independent of temperature.

explanation:

as given the equation is

2al + 6 hcl > 2 alcl3 + 3 h2(g)

as per equation two moles of aluminum reacts with six moles of hcl to give two moles of alcl3 and three moles of hydrogen gas

given: three moles of al are present and 7 moles of hcl

for three moles of aluminum nine moles of hcl will be required

however as 7 moles of hcl are present so the limiting reagent is hcl

hcl is going to decide the number of moles of product formed

when six moles of hcl are present = 3 moles of h2 are formed

when one mole of hcl is present == 3/6 mole sof h2 will be formed

when 7 moles of hcl are present = 3 x 7/ 6 moles of h2 will be formed = 3.5 moles of h2
