A star (Mr BUTTT) we got that wrong!!! it was Nano ones sure many got different values
well many got it wrong it depends on ur titre values if your titre values are reasonable then you get marksA star (Mr BUTTT) we got that wrong!!! it was Na
what hint?there was every slightest hint in the question it was Na.... didnt u ppl notice the last part of question 2???
i think so, coz i checked my calculations thricewell many got it wrong it depends on ur titre values if your titre values are reasonable then you get marks
I wrote the same, exactly and was no change actually observed with FA7 when Naoh + Al foil was added? Ohh Wasnt it add BaCl2 first and white precipitates formed and then you add HCL to those precipitates? The ones in FA6 dissolved in HCl while those in Fa7 did not confirming that it was a sulphate? That's how I did it because I remember it telling us to first add BaCl2 and then to the add HCl to the mixture :S Tell me if I'm wrong.is this for the last test where they just add Hcl to FA6 and Fa7? cause i remember 1st one for FA6 when you add Naoh with Al foil red litmus turns blue and ammonia is given off and for FA7 No change is seen then Hcl is added where in FA6 a brown gas appears confirming its Nitrite
Was the question after table was to find the maximum temperature or the maximum temperature change# Q1? :Swhat about the highest temperature? i got 27
Honestly i don't even remember what i wrote ahahahaI wrote the same, exactly and was no change actually observed with FA7 when Naoh + Al foil was added?

Maximum temperature, and the maximum temperature change was for the calculation part were i totally messed it upWas the question after table was to find the maximum temperature or the maximum temperature change# Q1? :S
I used Maximum Temperature instead and Volume of Fa2 for max temp in that question Would there b any ecf for next two parts? :/Maximum temperature, and the maximum temperature change was for the calculation part were i totally messed it up
yupI used Maximum Temperature instead and Volume of Fa2 for max temp in that question Would there b any ecf for next two parts? :/
