This question requires calculating mass. To determine the mass, we need values for two parameters, namely the specifications for the grade 70 tow chain and the mass per unit length given.
Assuming the mass per unit length is 3 kilograms per meter (kg/m) and the length of the grade 70 tow chain is 5 meters (m).
Thus, the formula used to compute the mass of the chain is as follows;
Mass of the chain = mass per unit length (kg/m) × length ---------------------------------------------------------------------------------------------------------------------(1).
5.451 X 10³ kg of sodium carbonate is required to neutralize 5.04×10³ kg of sulfuric acid solution.
Explanation:
Sodium carbonate neutralizes sulfuric acid (H₂SO₄). This compound is derived from a strong base (NaOH) and a weak acid (H₂CO₃). The chemical equation for this neutralization process is represented as:
Na₂CO₃ + H₂SO₄ ----> Na₂SO₄ + H₂CO₃
The balanced equation indicates that one mole of Na₂CO₃ is needed to neutralize one mole of H₂SO₄.
Molar mass of Na₂CO₃= 106 g/mol = 0.106 kg/mol, while Molar mass of H₂SO₄= 98 g/mol = 0.098 kg/mol.
To neutralize 0.098 kg of H₂SO₄, the required Na₂CO₃ is 0.106 kg, thus, to neutralize 5.04×10³ kg of H₂SO₄, Na₂CO₃ needed is 5.451 X 10³ kg.
