How many grams of H2 are needed to react with 47 grams of N2 to produce 200 grams of NH3?
Oduvanchick [21]
I think it’s law conservation of mass.

So 200g(NH3)-47g(N2)=153g(H2)

H2+N2—->NH3

How can the conductivity of a salt solution be decreased?
Musya8 [376]

Answer:

B. Add more water to decrease the concentration.

Explanation:

If we add more water to the solution, the concentration is decreased and like wise the conductivity of the solution.

  • Concentration is the amount of solute in a solution.
  • Conductivity deals with the ability of a solution to allow the passage of current.

Concentration and conductivity are directly proportional to one another. The higher the concentration, the higher the conductivity and vice versa.

  • Adding more water increases the amount of solvent and the concentration reduces.

What mass of aluminum sulfate is required to precipitate all of the Ba?? out of 45.0 mL of 0.548 M barium nitrate solution? 3 Ba
Verizon [17]

Answer:

2.82 g

Explanation:

Step 1: Write the balanced precipitation reaction

3 Ba(NO₃)₂ (aq) + Al₂(SO₄)₃ (aq) ⇒ 3 BaSO₄(s) + 2 Al(NO₃)₃(aq)

Step 2: Calculate the reacting moles of Ba(NO₃)₂

45.0 mL (0.0450 L) of 0.548 M Ba(NO₃)₂ react.

0.0450 L × 0.548 mol/L = 0.0247 mol

Step 3: Calculate the moles of Al₂(SO₄)₃ that react with 0.0247 moles of Ba(NO₃)₂

The molar ratio of Ba(NO₃)₂ to Al₂(SO₄)₃ is 3:1. The reacting moles of Al₂(SO₄)₃ are 1/3 × 0.0247 mol = 8.23 × 10⁻³ mol

Step 4: Calculate the mass corresponding to 8.23 × 10⁻³ moles of Al₂(SO₄)₃

The molar mass of Al₂(SO₄)₃ is 342.2 g/mol.

8.23 × 10⁻³ mol × 342.2 g/mol = 2.82 g
