Good luck on your assignment..
Answer:
Keq = [CO₂]/[O₂]
Explanation:
Step 1: Write the balanced equation for the reaction at equilibrium
C(s) + O₂(g) ⇄ CO₂(g)
Step 2: Write the expression for the equilibrium constant (Keq)
The equilibrium constant is equal to the product of the concentrations of the products raised to their stoichiometric coefficients divided by the product of the concentrations of the reactants raised to their stoichiometric coefficients. It only includes gases and aqueous species. The equilibrium constant for the given system is:
Keq = [CO₂]/[O₂]
Answer:
The mass of the bar is approximately 0.33 g.
Explanation:
q (heat in joules) = 1000 J
c (specific heat capacity) = 52 J/g°C
ΔT (change in temperature) = 80 - 22 = 58°C.
m (mass in grams) = ?
m = q / cΔT
m = 1000 J / (52 J/g°C) (58°C)
m = 0.33 g
hope this helps and is right!! p.s. i really need brainliest :)
