Suppose a state lottery prize of $2 million is to be paid in 20 payments of $100,000 each at the end of each of the next 20 years. If money is worth 9%, compounded annually, what is the present value of the prize?

what is the answer?

it depends on whether the reactant or product is solid or liquid. If it's solid you don't suppose to include in finding equilibrium concentration and the eq. will look like Kc=[B][C]

just multiply the concentration of Bx2=1.10Mx2L=2.2moles and then subtract the moles of A from calculated moles of B 5.00-2.2=2.8moles
