dolapo74:
The removal of rust from iron by treatment with H2SO4 is based on the
A hydrolysis of the iron
B reaction of acid with base
C oxidation of the rust
D dehydration of the iron

B is the answer.

REASON:
The reaction with tetraoxosulphate(vi)acid and iron rust(Fe2O3) is an acid-base reaction or neutralisation reaction because SALT...Fe2(SO4)3... and WATER is formed.

Equation of the reaction:

3H2SO4(aq) plus Fe2O3(s) ---> Fe2(SO4)3(aq) plus 3H2O

Please why use sin(tita) instead of cos or tan.... Please gurus explain

I think that's just the formula.

I hope you know that Iron rust is Hydrated Iron(III) Oxide,

Fe2O3. nH2O

Fe2O3. nH2O

Ofcourse,the compound is basic in nature because metals(iron in this case) generally react with oxygen to produce basic oxides.......which when reacted with acids give salt and water.

JAMB PHYSICS.

A student eats a dinner containing 8.0 * 10^6 Joules of energy. He wishes to do an equivalent amount of work in a nearby gym by lifting a 60Kg object. How many times must he raise the object to expand this much energy? Assume that he raises it a distance of 2.0m each time.
(A) 6.7 * 10^5 times
(B) 6.7 * 10^3 times
(C) 6.8 * 10^3 times
(D) 6.8 * 10^4 times


Physics gurus in the house please help outooooo.............this question don give me enough headache.

Show full workings......

As chiomamee has rightly said the answer is D
(one of) is used with a plural noun i.e. one out of many things
eg. one of the girls, one of the houses, one of the cars.

school is a count Noun it can be pluralise by adding(s).

then it is the form of our subject that will determines the form of our verb
so now what is the subject in the expression is? (One) note: (not schools)
since one is a singular subject the verb that follows must be a singular verb. i.e. suggests
option D: schools of thought suggests is correct

One of the schools of thought suggests selective marking of errors.

meaning
One out of the numerous schools of thought suggests selective marking of errors

the energy in one lift is mgh=60*10*2=1200J
To use up 8*10"6J of energy then he has to lift it 8*10'6/1200=6.7 *10'8 times
the answer is B

pre degree program- No
part time degree program - Yes
Diploma - Yes

He actually went d long way..just knw dat anything horizontal is cos, and vertical is sin but he added 10 to d sin to balance it even wen there was no 10 in d question...so it might be confusing at time, dats why i said strictly adhere to d formulae..thanks!

Pes13:
pre degree program- No
part time degree program - Yes
Diploma - Yes

Thanks
But how do one apply for the part time program or diploma program...?

pls what's the subject in that text sir,
I think should be A,
can I say
My dad slapped my mum and ME?or
My dad slapped my mum and I?
I learnt there's nothing like YOU and ME or I and YOU

What is now the correct answer to the question above.
My dad slapped my mum and ME? or
My dad slapped my mum and I?

What is now the correct answer to the question above. My dad slapped my mum and ME? or My dad slapped my mum and I?

ChiomaMee:


I can't wait to see you in Ui oo

can't wait to join u too dear.

Thanks

Samsonyte:


What is now the correct answer to the question above.
My dad slapped my mum and ME? or
My dad slapped my mum and I?

the question is trying to test our use of pronoun
first a subject is the doer of an action in a sentence while object is the receiver of the action
e.g. the man killed the snake in this example (the man) is the doer of the action i.e. the subject while the snake is the receiver of the action i.e object.

also you need to know the forms that pronouns can take. i.e subject or object

subject: I we he she
object :me us him her

now if we look at the question again u will see that the speaker and his mum are the receiver of the action i.e. (objects) therefore if you using a pronoun instead, it has to be an object pronoun.
so,
My dad slapped my mum and (ME) object pronoun correct

or the sentence can be better rephrased as
My dad slapped me and my mum

I just went through an article online, which clearly states that OOU does not consider second choice applicants,no matter your jamb score and post UTME, but I picked the school as my second choice, and I chose Agricultural economics which had a total of 21 applicants last year,my question now is that since the number of applicants isn't much can't I be considered?
or who else knows a state university that accepts second choice applicants?
or should I change it to my first choice to be sure of getting admitted?
U.I's the first choice

There is no school that accept second choice now, it must be first choice.
What you can do is dat, u will do oou post UTME first without changing it to first choice because oou will not fetch ur information from jamb, so after doing the post UTME, ur score will determine whether u will change it to first choice or not.
