Suppose you have 45 g of salt dissolved in 150 mL of water and are told that you need 250 mL more of the same solution. How much salt do you need to make the
additional solution?

Consider the following reaction at equilibrium: c(s)+h2o(g)⇌co(g)+h2(g) predict whether the reaction will shift left, shift right, or remain unchanged upon each of the following disturbances. a) c is added to the reaction mixture. b) h2ois condensed and removed from the reaction mixture c) co is added to the reaction mixture d) h2 is removed from the reaction mixture.
