    I used the Mr method. Mr of CaCO3 divided by Mr of CaCO3+ Mg(OH)2 x 0.500.

    Tell me, how is that method wrong? That CaCO3 one?

    Not sure if it did.

    Moles of products were 'lesser'. Decreasing the pressure would shift the equilibrium to the right side.

    No -_- Moles on the right were more.

    Not exactly. But I'm 500% sure the moles of Products were more. That's why I opted for a decrease in pressure. Adding a reactant won't change the state of equilibrium.

    It's wrong.

    Wrote decrease in pressure. How was it not right? Moles of products were more. So decreasing the pressure would shift the equilibrium towards the product, that was chlorine.

    Damn it :O I used the method of Mr. Mr of CaCO3 divided by Mr of the antacid tablet x mass of tablet.

    Wrote H+ too :p

    I got the mass of CaCO3 0.31 grams. 100/158 x 0.500.

    No :/ Wrong.

    100/158 x o.500 makes 0.31.

    Why not NO3-?

    Chemistry P1 and P2 today

    Guys. What were the moles of CO2 produced in that tablet question? What was the energy released in the CO question? What was the answer to the equilibrium mcq which said, add more hcl, pressure etc. AND, X didn't have NO3-? How? NaOH was added and acidified. Ammonia was produced. That's the...

    Are you crazy? It said NaOH was added and it was acidified. Ammonia was being produced. It had to be NO3-.
  19. Haris Sal11

    Chemistry P1 and P2 today

    Wrote NO3- as well.

    NO! It's correct.
