DKrown:

Is that for everybody? I mean is it all of us that will write maths? Cos I applied for biochemistry.

Eben331:
Give me ur email. We need to talk. I am unable to pm u via Nairaland, I don't knw the reason.

TeflonBlixx:


Are you not on facebook or whatsapp??

Eben331:
You can delete ur mail now from ur earlier post...I am on facebook but not on WhatsApp for now. I will send my facebook username to u through email.

Eben331:
No. Just keep checking your portal and email or maybe sms.

Gud day everyone, greeting to everyone,.

Let me be biased, special greetings to all MBBS aspirants.

By now everyone should be almost ready for the battle ahead.

To all mbbs, remember you are fighting a battle at the ratio of 1 applicant versus 100 applicants.

During my aspiring days, a total of 146 student were admitted in my class while over 11,000 choose UI MBBS from jamb.

so, get your battle axe ready, prepare for war, the warfront is deadly.

Even nairalanders will not pity you, they are ready to strike you into physiology and biochemistry department, if you don't strike them first. Fight with all within you.

But, remember, you need God in this race. The race Is not for the swift. Read, pray, and spank 90% in prime.

Which of the following has the highest degree of hardness? (A) rain water (B) lake water (C) borehole water (D) river water PLS EXPLANATIONS WILL BE NEEDED!!

TeflonBlixx:
i

What do you think the cutoff will be this year based on jamb score alone. . Thinking about it scares the bat shit outta me.

Besides, what are the other inclusions in the use of english part from comprehension, synonyms and antonyms?

Eben331:
Pls bosses in the house, help me with these questions. CHEMISTRY (1) As a supplification, adult human can be considered to have a daily diet of 180kg of carbohydrates with empirical formula CH20. What mass of CO2 does a person produce each day if all the carbohydrates eaten is digested and oxidized? (C=12, H=1, O=16) (2) The solubility of AgCl at 50^oC is 1.024 per 100g of solvent, and at 10^oC, it is 2.15g. Calculate the mass of silver chloride precipitated when saturated solution of 50g AgCl was cooled from 50^oC to 10^oC. (Ag=108, Cl=35.5) (3) In an insulated container, 50cm^3 of 2M of HCl is at 293K. After reaction, the temperature of the mixture rose to 307K. Calculate the enthalpy change of reaction. (c=4.2J/g/K) (4) During the electrolysis of CuSO4 solution using platinum electrode, 0.16g of copper was deposited on the cathode. Calculate the volume of oxygen gas liberated at stp (Cu=64, O=16) PLS SHOW YOUR WORKINGS!!

Eben331:
Someone should pls solve these.

Pes13:


until after putme, anything can happen, I knew some of my mate who scored 300+ but couldn't score more than 65%, though he made it while I knew a department mate who scored 268, and still made it.

There was even someone who entered with 218, I saw it with my eyes, I wasn't told.

why am I telling u this? , focus on putme, your jamb score alone can't help you or determine your chance.

TeflonBlixx:

Alright thanks

Guys I heard that "market women calculator" (not scientific calculator) is allowed for post utme, please how true is dis?

1. C6H12O6 + 12O2 -- 6CO2 + 6H2O

Molar mass of the carbohydrate = 180g

Using first principle..

180g --- 264g
180000-- y

y = 180000 x 264/ 180

y - 264kg

2. still on it

3. Volume = 50cm^3
1cm^3 - 1g
T1 -- 293K
T2 -- 307K

H = Mc * change in theta
= 50 x 4.2 x (307 - 293)
= 2940J

Find the amount of Hcl that will liberate 2940J

Molar concentration = Amount/Volume

2 = a/ 0.05
a = 0.1

Therefore. .

0.1 mole liberate 2940J of energy
1 mole will liberate

1 x 2940/ 0.1

-- 29400J x 2
58800j or so
... I'm not sure about this one, will check later..

4. From the second law of electrolysis...

m/M x c = m/M xc

0.16/64 x 2 = m/32 x 4

5 x 10^-3 = 4m/32

4m = 0.16
m = 0.04
Therefore. . 32g---- 22.4
--------- 0.04 --- p
22.4 x 0.04/32 = p
p -- 0.028dm^3

it should lake, because it does not flow. lol!

ummmm this question...
but I think the answer is rain water
rain water contains caco3

Probity567:
Lake water has the highest degree of hardness,bcus of its stationary nature. It accumulate more soluble calcium,magnesium and iron(iii)salts. The other source are soft, bcus they are less exposed to these salts.

rain water is nt hard, if river is correct lake is also correct. river and lake are hard but not compare to borehole. borehole water contains dissolve air and minerals e.g Ca jand Mg, limestone,chalk from underground deposit. and u knw hard water is very good for the body, moreover soft water attack lead pipe because it leads to lead poisoning, so borehole water is the hardest.

A rope 5m long is fastened to two hooks 4m apart on a horizontal ceiling. To the rope is attached a 10kg mass so that the segments of the rope are 3m and 2m. Compute the tension in each segment. PLS SHOW YOUR WORKINGS!!

Eben331:
Pls guys, I need solution to this question. This question weak me.
