Answer:
Mass = 12.48 g
Explanation:
Given data:
Mass of sulfur dioxide = 25.0 g
Mass of sulfur formed = ?
Solution:
Chemical equation:
SO₂ → S + O₂
Number of moles of SO₂:
Number of moles = mass/molar mass
Number of moles = 25.0 g / 64.07 g/mol
Number of moles = 0.39 mol
Now we will compare the moles of SO₂ with S.
SO₂ : S
1 : 1
0.39 : 0.39
Mass of sulfur:
Mass = number of moles × molar mass
Mass = 0.39 mol × 32 g/mol
Mass = 12.48 g
Weak acids only partially ionize. so the retain part of the original molecule. C

Put a 2 on the HCl.
2HCl+Ba-->BaCl2+H2
Answer:
Reaction is already balanced
Explanation:
The equation in reaction 1 is given as;
CH3COOH + NaHCO3 --> CO2 + H2O + Na+ + CH3COO-
The reaction is already balanced. This is because the umber of atoms of elements in the reactant is equal to that of the products
Carbon
Reactant = 2 + 1 = 3
Product = 2 + 2 = 3
Hydrogen
Reactant = 3 + 1 + 1 = 5
Product = 2 + 3 = 5
Oxygen
Reactant = 2 + 3 = 5
Product = 2 +1 + 2 = 5
Sodium
Reactant = 1
Product = 1
