Answer:
option A = S(s) + O₂(g) → SO₂ (s)
Explanation:
Chemical equation:
S(s) + O₂(g) → SO₂ (s)
when sulfur burned in the presence of oxygen it produce sulfur dioxide. The sulfur dioxide can further react with oxygen to produce sulfur trioxide and then react with water to form sulfuric acid.
Uses of sulfur dioxde:
It is used as a solvent and reagent in laboratory.
Sulfur dioxide is used to produce sulfuric acid.
It is used as a disinfectant
It is also used as a reducing agent.
It is used to preserve the dry food.
Molarmass of beryllium is 9.0
molar mass of silicon is 28.4
molar mass of calcium is 40.1
molar mass of rhodium is 103.
Using Avogadros number, we can get that 1 mole of an atom
contain 6.022 x 10^23 atoms. Therefore we can use this conversion factor to get
the number of moles:
moles ZnCO3 = 6.11 x 10^22 atoms * (1 mole / 6.022 x 10^23
atoms) = 0.10146 moles
The molar mass of ZnCO3 is about 125.39 g/mol, therefore the
mass is:
mass ZnCO3 = 0.10146 moles * (125.39 g / mol)
<span>mass ZnCO3 = 12.72 g</span>
