I don,t have lit in my o level buh I did it in jamb.hope no prob.

A 600ml of water was added to 200ml of a 1.6M CaCl2 solution...what is the concentration of chloride in the new solution....(A) 0.4 (B) 0.8 (C) 1.2 (D) 5.6
PS....if u r in Ibadan,it will be of good help,if you can go to Team tutor...u will be expose to a lot of question like this....

I'll go for 0.4M.
just WURUWURU TO THE ANSWER

..wrong but u tried....there is a small mistake along ur calculation....
Bro,are u interested in the reading group?

DrBESTJC:
CHEMISTRY.

1 : Calculate the pH of 0.2 mol dm^-3 of Ca(OH)2, assuming that Ca(OH)2 is a strong electrolyte.
(A) 10.6
(B) 12.5
(C) 5.1
(D) 8.0

2 : The concentration of H3O+(oxonium) ions in 1.0 mol dm^-3 solution of C6H5COOH(benzoic acid) is 8.0 * 10^-3 mole per dm^3.Calculate its percentage ionization......
(A) 0.545%
(B) 0.888%
(C) 0.213%
(D) 0.725%

...both question are wrong...
No 1.. Its simple BT wrong.....the most important aspect its just to mutiply the hydroxide concentration by 2 and then find POH.......PH = 14 - POH....

No 2....its also simple....percentage of ionisation
=( hydroxonium concentration/original acid present) × 100%...=( 8 × 10^-3/ 1) × 100...
= 0.8 %....there r some complicated question where hydroxonium ion concentration is not given but Ka is given....

..show workings...u are right anyway..

Pls I need some information,if dia is anyone applying to UI dis year through direct entry,can u contact m on whatapp Oseven 066 fourtytwo 6311.. I will appreciate.

Abi o. I am even fed up with him concerning this matter. I have told him many times to show us the corrections to his questions.

....don't vex jare..I will solve them when we get to those topics in our reading group....it seems u r not on what's app....it doesn't mata though...hope u r gearing for d reading adventure....

dat surface tension na

This is the first question

Dry steam at 100°C is bubbled into 500g of water originally at 20°C. What will be the temperature of the water after 30g of steam has condensed? Specific latent heat of steam is 2.26*10^6J/k, specific heat capacity of water is 4200J/Kg/k


And this is the second question

Calculate the total energy required to evaporate completely 1kg of ice that is initially at -10°C.
Specific heat capacity of ice is 2.2x10^3J/Kg/K
Specific heat capacity of water is 4.18x10^3J/kg/k
Specific latent heat of ice is 3.34x10^5J/kg
Specific latent heat of vaporization of water is 2.26x10^6J/kg..

pls

Is DE form still on sale?

I need urgent reply please!!!

Reading group alert!!!...it begin 2nit...may 7 -
june7... recruitment is still going on....for science student,we are doing physics for one month....tonight we are doing 2 topics.."Work Energy and Power",Efficiency and Machine( levers,inclined plane,screw)... 1983 jamb pq...ui practice question related to the topics...
The outline of both topics will be given on whats app.. You can still join if you are interested..

For art and commercial student,you just choose the subject and topic you want to read...just make sure that you finish a subject in a month..

from my own view oo. 80% of ui post utme questions are jamb questions

Excuse me o is this thread only for science students

Awon igi iwe lo a nibi yi Ooooooo!!!!!!!!!!!!!! If I. Get to UI now, will I cope?

thanks

Only 50 candidates got admitted into the Department of Mechanical Engineering. Does this means that only 50 candidates beat the cut - off point... {just thinking loud}
