Answer:
A) 1.68 L
Explanation:
- Charles’ Law states that: at constant pressure, the volume is directly proportional to the temperature of the gas.
- It can be expressed as: V₁T₂ = V₂T₁,
V₁ = 1.2 L, T₁ = 175.0 K, V₂ = ??? L, T₂ = 245.0 K.
∴ V₂ = V₁T₂/T₁ = (1.2 L)(245.0 K)/(175.0 K) = 1.68 L.
Answer:
Answer is: Keq = [CO₂].
Explanation:
Balanced chemical reaction: CaCO3(s) ⇄ CaO(s) + CO₂(g).
The equilibrium constant (Keq) is a ratio of the concentration of the products to the concentration of the reactants.
Pure liquids (shown in chemical reactions by appending (l) to the chemical formula) and solids (shown in chemical equations by appending (s) to the chemical formula) not go in to he equilibrium constant expression, only gas state (shown in chemical reactions by appending (g) to the chemical formula) reactants and products go in to the equilibrium constant expression
