Answer:
T = 58 + 273.15 = 331.15
R = 0.082 atm
V = 250.0 mL / 1000 = 0.25 L
P = n x R x T / V
P = 2.48 x 0.082 x 331.15 / 0.25
P = 67.342 / 0.25
P = 269.368 atm
Explanation:
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
Answer:
D
Explanation:
The answer will be D because as we can deduct from the hypothesis, he will try to control the amount of food he gives the rats in order to see if in fact the fue of the mouse will be shinier
