Answer:
V2 = 1/4
Explanation: P1 = 1; P2 = 2; V1 = 1/2; V2 = ?
P1*V1 = P2*V2
∴ V2 = P1*V1/P2 = {1 X 1/2}/2 = 1/4
Balance Chemical Equation is,
<span>CaO </span>₍s₎ <span>+ CO</span>₂ ₍g₎ <span>→ CaCO</span>₃ ₍s₎
According to Equation
56.07 g of CaO when reacted with excess CO₂ produces = 100.08 g of CaCO₃.
Then,
1.8 g of CaO is reacted with excess CO₂ = X g of CaCO₃ will produce.
Solving for X,
X = (100.08 g × 1.8 g) ÷ 56. 07 g
X = 3.21 g of CaCO₃
Answer:
<h2>The answer is 28.2 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume of table = 12 cm³
density = 2.35 g/cm³
The mass of the table is
mass = 2.35 × 12
We have the final answer as
<h3>28.2 g</h3>
