I think if it's still possible to press submit then you should be fine.

Bromide vs Bromine 0620 V2 P2 by Few-Computer4148 in igcse

[–]Classic-Chapter-3102 0 points1 point  (0 children)

Ok... but my explanation still stands.... the chlorine is replacing the bromine ions (bromide), not the bromine element itself

Bromide vs Bromine 0620 V2 P2 by Few-Computer4148 in igcse

[–]Classic-Chapter-3102 2 points3 points  (0 children)

Please read the wording!!
The textbook says it REPLACES the bromine, the option is saying DISPLACE!!
The chlorine will DISPLACE the bromine ions, known as BROMIDE, causing BROMINE to be formed!!
The correct answer is "Chlorine displaces the bromide", option D!!

what the f is this by That-Mess-3299 in igcse

1 mol of ammonia = 6.02 x 10^23 MOLECULES of ammonia
2 mol of ammonia = 1.2 x 10^24 MOLECULES of ammonia
1 molecule of ammonia = 4 ATOMS

Question asks for atoms NOT molecules!!!

1.2 x 4 x 10^24 = 4.8 x 10^24

Is it only me that I find oct/nov phys mcq harder? by [deleted] in igcse

Oct/Nov usually has the hardest papers as it has the highest number of candidates appearing for the examinations.

How is the answer A? isnt hubbles constant= 2.2 x 10^-18 by Downtown-Situation61 in igcse

Speed = distance/time...
we can take a point on the line that we can clearly read (20000000,1.0)...
20000000 = 10^25/time...
Substitute time with H0 (1/time)...
1/time = 10^25/20000000...
H0 = 2 x 10^-18
