O.N. of Na = +1
O.N. of O = -2
Let, O.N. of Tin = x
1*2 + x + -2*2 = 0
2+x-4 = 0
x-2 = 0
x = 2
SO OPTION C IS YOUR ANSWER......
Answer:
Calcium (Ca) - will lose electrons
Sulfur (S) - will gain electrons
Carbon (C) could lose or gain electrons
Neon (Ne) Does not gain or lose electrons
The mole ratio of PbO2 to water in
Pb + PbO2 +2 H2SO4 = 2PbSO4 + 2H2O is
1 :2
1 mole of Pb reacted with 1 mole of PbO2 and 2 moles of H2SO4 to form 2 moles of PbSO4 and 2 moles of H2O
therefore the mole ratio of Pbo2 to H2O is 1:2
Answer:
Explanation:

Answer:
Mass = 101891.2 g
Explanation:
Given data:
Mass of ammonia needed = ?
Mass of ammonium sulfate produced = 396 Kg = 396 ×1000 = 396000 g
Solution:
Chemical equation:
2NH₃ + H₂SO₄ → (NH₄)₂SO₄
Number of moles of (NH₄)₂SO₄:
Number of moles = mass/molar mass
Number of moles = 396000 g / 132.14 g/mol
Number of moles = 2996.8 mol
Now we will compare the moles of ammonia and ammonium sulfate
(NH₄)₂SO₄ : NH₃
1 : 2
2996.8 : 2/1×2996.8 = 5993.6 mol
Mass of ammonia needed:
Mass = number of moles × molar mass
Mass = 5993.6 mol × 17 g/mol
Mass = 101891.2 g
