In the formation of alum, the initial filtration step is used to A. concentrate the aluminum hydroxide

B. remove impurities that were in the aluminum foil

C. remove impurities from the KOH

Fill in the coefficients that will balance the following reaction: a0cr2(so4)3 + a1agno3

Define dew point. i am writing this part to be able to ask the question

The reactions shown here can be combined to make the overall reaction c(s) + h2o(g) ⇌ co(g) + h2(g) by reversing some and/or dividing all the coefficients by a number. a. c(s) + o2(g) → co2(g) k=1.363×10^69 b. 2 h2(g) + o2(g) → 2 h2o(g) k=1.389×10^80 c. 2co(g) + o2 (g) → 2 co2(g) k=1.477×10^90
