Explanation:
Find the motion diagram attached for the illustration:
Distance is the length of path traveled from the start to the finish. In measuring distance, we wall through the path from start to the finishing point. Distance is a scalar magnitude that has magnitude but no direction.
Displacement is distance that is taken between the start and finishing point. It is a vector quantity that has magnitude and measures direction.
To find the distance;
Distance = 5km + 7km = 12km
Displacement:
Using pythagoras theorem;
Displacement = √7² + 5² = 8.6km
Direction:
sin(bearing ) =
bearing = arcSin 0.5814 = 035.6°
Displacement is 8.6km in a direction 035.6°

Sodium carbonate is used to neutralised sulfuric acid, H₂SO₄. Sodium carbonate is the salt of stron base (NaOH) and weak acid (H₂CO₃). The balanced chemical reaction for neutralization is as follows:
Na₂CO₃ + H₂SO₄→ Na₂SO₄ + H₂CO₃
From balanced chemical equation, it is clear that one mole of Na₂CO₃ is required to neutralize one mole of H₂SO₄. Molar mass of Na₂CO₃= 106 g/mol=0.106 kg/mol and molar mass of H₂SO₄= 98 g/mol=0.098 kg/mol.
To neutralize 0.098 kg of H₂SO₄ amount of Na₂CO₃ required is 0.106 kg, so, to neutralize 5.04×10³ kg of H₂SO₄, Na₂CO₃ required is= kg= 5.451 X 10³ kg.
