A bin contains 25 balls: 10 red, 8 yellow, and 7 blue. We draw three balls at random (without looking!) from the bin, and we will say that we "win" if our three balls represent exactly two colors. (That is, we "win" if we draw two balls of one color and another ball of a different color.) What is the probability of winning this particular game?

The answer is CaSO3 -> CaO + SO2. I understand that when SO3 is in a vacuum...it turns to SO2...but I don't get how you predict the other product (CaO)...is it just a format that I just have to memorize?

i can't seem to find any household products i have at home that include either..
calcium sulfate or sodium silicate.
i asked a similar question on yahoo before, and that helped a lot..but i realize, i don't have any products at home with these ingredients...
i thought baking powder had calcium sulfate, but uh, it said something like calcium bicarbonate instead? something like that.
and as for the sodium silicate...i don't eat preserved eggs, and so..i don't think i have anything at home with it...
can anyone suggest any household products that may include either calcium sulfate or sodium silicate in their ingredients? heh, thank youu.
