Answer:
The answer to your question is below
Explanation:
H₂SO₄ = sulphuric acid
KOH = potassium hydroxide
This is a neutralization reaction
H₂SO₄ + 2 KOH ⇒ K₂SO₄ + 2H₂O
2 ----------- K ----------- 2
1 ----------- S ---------- 1
4 ---------- H --------- 4
6 ------------ O ---------- 6
Answer: 850.0 g/min.
Explanation:
- The rate of the reaction = (ΔC/Δt) where,
ΔC is the change in concentration of reactants or products.
Δt is the change in time of the reaction proceeding.
- The rate is needed to be calculated in (g/min).
- We need to calculate the amount of the product in (g) via using the relation (n = mass / molar mass).
- mass (g) = n x molar mass,
- n = 1.5 moles and molar mass of P₄O₁₀ = 283.88 g/mol.
- m = 1.5 x 283.88 = 425.82 g.
- ΔC = 425.82 g and Δt = 30 s / 60 = 0.5 min.
- The rate of the reaction = ΔC / Δt = (425.82 g / 0.5 min) = 851.64 g/min.
<em>can be approximated to 850.0 g/min.</em>
Answer:
Salt has long been used for flavoring and for preserving food. It has also been used in tanning, dyeing and bleaching, and the production of pottery, soap, and chlorine. Today, it is widely used in the chemical industry.
