Answer: When you put a hot object in contact with a cold one it heat will flow from the warmer to the cooler. and as a result the warmer one will be usually cool down and the cooler one will usually warm up. Eventually, they will reach the same temperature and heat flow will stop.
Explanation: Hope this helps
Answer:
Pretty sure the answer is A on Plato
Explanation:
I looked it up, and it said that raising the temperature would cause the equilibrium to shift left.
Answer is: <span> the equilibrium concentration of Br</span>₂ is 0,02 mol/L.<span>
</span>Chemical reaction: Br₂ + Cl₂ → 2BrCl.
Kc = 7,0.
c₀(Br₂) = 0,25 mol ÷ 3 L.
c₀(Br₂) = 0,083 mol/L.
c₀(Cl₂) = 0,55 mol ÷ 3 L.
c₀(Cl₂) = 0,183 mol/L.
Kc = c(BrCl)² ÷ c(Br₂) · c(Cl₂).
7 = (2x)² ÷ (0,083 mol/L - x) · (0,183 mol/L - x).
7 = 4x² ÷ (0,083 mol/L - x) · (0,183 mol/L - x).
Solve q<span>uadratic equation: x = 0,063 mol/L.
</span>c(Br₂) = 0,083 mol/L - 0,063 mol/L = 0,02 mol/L.
Acetic acid. Hope this helps :)
