B is identified as an ionic compound. Explanation: This conclusion is drawn based on the characteristics of ionic compounds, which typically form crystals similar to salt (sodium chloride), are soluble in water, exhibit high boiling and melting points, possess hardness from strong intermolecular forces, and can conduct electricity—though only when dissolved or in a molten state.
Response:
The accurate choice is;
Sulfur oxides linked to acid precipitation
Details:
Sulfur oxide in the atmosphere interacts with oxygen, water, and other chemicals leading to the creation of acidic precipitation known as acid rain.
Sulfur oxides react with moisture in clouds to generate sulfuric acid as follows;
The sulfur gas undergoes initial oxidation
SO₂ + OH → HOSO₂
The subsequent step involves producing sulfur trioxide
HOSO₂ + O₂ → HO₂ + SO₃
Finally, sulfur trioxide reacts with water to yield sulfuric acid
SO₃ + H₂O → H₂SO₄ (aq).
2C6H14 + 13O2 ---> 6CO2 +14H2O
Calculating the molar mass of C6H14: M(C6H14)=12.011*6 +1.008*14 ≈ 86.17 g/mol
Thus, 86.17 g of C6H14 corresponds to 1 mole.
2C6H14 + 13O2 ---> 6CO2 +14H2O
based on the equation 2 mol 6 mol
according to the question 1 mol 3 mol
To determine M(CO2): M(CO2)= 12.011 + 2*15.999= 44.009 g/mol
Therefore, 3 mol CO2*44.009 g/1 mol CO2 ≈ 132.0 g CO2
Final answer: 132.0 g CO2
