Answer:
B. 75.0 kPa
Explanation:
P1V1/T1=P2V2/T2
(x * 100 L)/(300 K)=(100 kPa * 50.0 L)/(200 K)
x=75.0 kPa
Carbon 12 and carbon 14 are two isotopes of the elements carbon.the difference between carbon 12 and carbon 14 is the number r of neutrons in each atom.the number given after the atom name (carbon) indicates the numbers of protons plus neutron is an atom or iron. Atom of both isotopes of carbon contain 6 protons
Overall, it depends on your opinion. Some people think roses are prettier than daisies, and daisies are prettier than roses.
Roses are the definitive symbol for love and appreciation, while daisies are a symbol of Virgin Mary representing her chastity, grace, and purity. Daisies represent beauty and patience as well.
As the reaction equation is:
COCl4(aq) + 6 H2O(l) ↔ CO (H2O)6(aq) +4 Cl + Heat (missing in your question)
(Blue) (pink)
So the correct answer which reflects the temperature effects is (b) increasing the temperature changes the solution to blue indicating that the equilibrium shifts to the left and decreasing the temperature changes the solution to pink indicating that the equilibrium shifts to right.
- as when the heat increases (and it's a product) the reaction move towards the reactants to increase the reactants to make the equilibrium again so it shifts leftwards and COCl4 which has the blue indicator will increase to make the equilibrium.
-But when the temperature decreases the reaction move towards the products to increase the products (which the heat one of them) to make equilibrium again so, it shifts rightwards and CO(H2O)6 (which has the pink indicator) will increase to make the equilibrium.
