Which of the following has the greatest heat capacity?
2 answers:
Answer: a. 1,000 g of water
Explanation:
Heat capacity is defined as the amount of heat required to raise the temperature of a substance through 1 degree Celsius.
Q= heat gained
m= mass of the substance
c = heat capacity
Heat capacity of water =
Heat capacity of steel =
Hence 1,000 g of water will have greatest heat capacity.

Answer:
Rate of formation of SO₃ = 7.28 x 10⁻³ M/s
Explanation:
According to equation 2 SO₂(g) + O₂(g) → 2 SO₃(g)
Rate of disappearance of reactants = rate of appearance of products
⇒ -----------------------------(1)
Given that the rate of disappearance of oxygen = = 3.64 x 10⁻³ M/s
So the rate of formation of SO₃ = ?
from equation (1) we can write
⇒ = 2 x 3.64 x 10⁻³ M/s
⇒ = 7.28 x 10⁻³ M/s
∴ So the rate of formation of SO₃ = 7.28 x 10⁻³ M/s
