Imagine that instead of balls, you were rolling positively charged ions of the same element).
Ghella [55]
The ion with a +3 charge would be deflected the most by the magnet because it has the strongest positive charge therefore it will be the one being the most repelled. and the ion that would be deflected the least would be the ion with a +1 charge because it has the least amount of charge so the magnet will still repel it but just not as much as it will repel the ion with a +3 charge.

hope that helps

2NO(g) N2(g) + O2(g); Keq = 2.1 × 1030 What does the value of the equilibrium constant indicate?
olga_2 [115]
The equilibrium constant is a value which represents the equilibrium of a reaction. It is a reaction quotient when the reaction reached equilibrium. If Keq is greater than 1, the mixture contains mostly the products. On the other hand, if Keq is less than 1, the mixture contains the reactants. For this case, the mixture contains mostly products.

ammonia gas reacts with oxygen gas, o2(g), to produce nitrogen dioxide and water. when 28.5 g of ammonia gas reacts with 83.4 g
jolli1 [7]

The percent yield of the reaction between ammonia gas with oxygen gas is 90.52%.

A chemical reaction between ammonia gas (NH3) with oxygen gas (O2)

NH₃ + O₂ → NO₂ + H₂O

The balanced reaction 4NH₃ + 7O₂ → 4NO₂ + 6H₂O

Calculate the number of moles from the reactant

  • Ammonia gas
    Molar mass N = 14 gr/mol
    Molar mass H = 1 gr/mol
    Molar mass NH₃ = 14 + (3 × 1) = 14 + 3 = 17 gr/mol
    mass = 28.5 grams
    n = m ÷ molar mass = 28.5 ÷ 17 = 1.68 mol
  • Oxygen gas
    Molar mass O = 16 gr/mol
    Molar mass O₂ = 16 × 2 = 32 gr/mol
    mass = 83.4 grams
    n = m ÷ molar mass = 83.4 ÷ 32 = 2.61 mol
  • n O₂ ÷ coefficient O₂ = 2.61 ÷ 7 = 0.37
    n NH₃ ÷ coefficient NH₃ = 1.68 ÷ 4 = 0.42
    0.42 > 0.37 it means that the ammonia gas is in excess and the O₂ is limiting.

According to stoichiometry, the number of moles NO₂ with the number of moles O₂ has the ratio with the coefficient in reaction.

  • Theoretically the number moles of NO₂
    n O₂ : n NO₂ = 7 : 4
    2.61 : n NO₂ = 7 : 4
    n NO₂ = 4 x 2.61 : 7 = 1.49 mol
  • The actual number of moles NO₂
    Molar mas NO₂ = 14 + (16 × 2) = 14 + 32 = 46 gr/mol
    n NO₂ = m ÷ molar mass = 61.9 ÷ 46 = 1.35 mol

The percent yield NO₂ is the ratio of the actual number of moles NO₂ with the theoretical number of moles NO₂ times 100%.

P = (1.35 ÷ 1.49) × 100%

P = 0.9052 × 100%

P = 90.52%
