I complete the Squar3
Agree !far out looking at this forum, i have already lost a solid 5 marks in the MC, although the one word response/long response questions should compensate as im expecting near 45/50 for them combined.

OH shtttt
It can't be that technical!OH shtttt
there goes another mark.
It's not, you can't even fit that reaction into the boxes anyway. It's definately precipitation.It can't be that technical!
you never need to out a balanced chemical equation in the school certificate, only in the HSC, so the correct answer is KOHIt can't be that technical!
That's in the year 11 syllabus and has to do with precipitation since I just learned it at tutor :') Double displacement is just the overall term used to describe reactions such as precipitation, acid + base, acid + carbonate and yeah...
I was talking about the precipitation question not about KOH (potassium hydroxide) I thinkyou never need to out a balanced chemical equation in the school certificate, only in the HSC, so the correct answer is KOH
sorryI was talking about the precipitation question not about KOH (potassium hydroxide) I think
I believe I did carbonate. Then the gas was Carbon Dioxide.what did you guys get for the um... powder mixed with liquid and turns into a milky(?) substance and has the bubbles in it?
I had CO2 as the gas that was in it and then the acid+carbonate reaction as the 2nd answer for that...but not surewhat did you guys get for the um... powder mixed with liquid and turns into a milky(?) substance and has the bubbles in it?
I did hydrogen since the liquid was clear so it can't be CO2. Then was an acid+metal = salt + hydrogen reaction.what did you guys get for the um... powder mixed with liquid and turns into a milky(?) substance and has the bubbles in it?
Didn't it say it was bubbled through limewater which turned milky? That would mean it'd be CO2I did hydrogen since the liquid was clear so it can't be CO2. Then was an acid+metal = salt + hydrogen reaction.
Really? I didn't read that anywhere:/ FMLDidn't it say it was bubbled through limewater which turned milky? That would mean it'd be CO2
