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.
Answer:
Positive acceleration involves speeding up, while negative acceleration involves slowing down.
Explanation:
I am so sorry if I was wrong!
62.3018 g/mol is the molar mass
Answer:
The answer to your question is 0.1595 mg of Oxygen
Explanation:
Data
K = 38.67 g
N = 13.86 g
O = ?
Mass of oxygen in 336 mg
Process
1.- Convert 336 mg to grams
1000 mg ----------------- 1 g
336 mg ---------------- x
x = (336 x 1)/1000
x = 0.336 g of sample
2.- Calculate the mass of oxygen in 100g
Mass of oxygen = 100g - 38.67g - 13.86g
= 47.47 g
This means that oxygen represents 47.47% of the sample
3.- Calculate the grams of Oxygen in 0.336 mg.
Mass of Oxygen = (0.336)(0.4747)
Mass of Oxygen = 0.1595 mg
