seydam21: 1. B
2. White phosphorus nt phosphorus alone...it store under water from been catch fire because it is inflamable
3. c
4. Mantle
5 xy
6. c

U got all right except no 6, d answer is chromosome.

N.B - both white and red phosphorus are inflammable, its just dat white phosphorus av a higher tendency of catching fire

Yungmilio2: are you sure?
Mr staylite
Lol who you wan see?
facing my book

What do u realy want frm dis guy na??

Divsy: D resistance of a piece of wire of length 20m,cross sectional area 8.0x10^-6 nd resistivity 4.0x10^-7^2-m

R=(rol)l/A

Rol(resistivity)=4.0x10^2
L=20m
A=8.0x10^-6

R=(4.0x10^2)(20)/(8.0x10^-6)
R=(80x10^2)/(8.0x10^-6)
R=10x10^8

D exam has come and gone.
Let's hope for best.

seydam21: f*ck your calculator bro! press it again for d division

Oops.. Tnx
D answer is 30km/hr

seydam21: An Athlete runs 100m in 12s. What is his speed in KW/H?

Speed=distance/time.

100m=0.1km
12s=0.00333hr.
Speed=0.1/0.00333
Speed=30km/hr

Divsy: A body of mass 2kg,moving with a velocity of 5m/s collides with stationary body of mass 0.5kg if d 2 bodies move 2geda after impact,calculate their common velocity..*show workins pls

M1u1+m2u2=(m1+m2)V
(2*5)+(0.5*0)=(2+0.5)V
10=2.5v
V=4m/s.

seydam21: Acetonitrile

Other names
*Cyanomethane
*Ethanenitrile
*Ethyl nitrile
*Methanecarbonitrile
*Methyl cyanide

The IUPAC name is Ethanonitrile.

Divsy: baleen plates

Correct, Baleen.

eadeyeye2: This is a past question on mathematics, I dont understand it also. No 60 (the result of dividing...........) Meanwhile i greet all the elders in the house Good afternoon o

Please dnt mind my bad handwriting.

What some whales have intead of teeth is?

Divsy: y is it nt translation

The two ar similar but different terms.
Transcription occurs when codes in d DNA is converted into equivalent code in RNA while translation 2 my understanding is d synthesis(conversion) of a protein from RNA "form" 2 amino acid "form" in a protein.

PLEASE correct if I am wrong.

Divsy: d oda ansas ar correct xcept 4 no.3wic is metamerism tho nt in d option..

Ok. Pls is d Biology post utme past questn with u?

Collee: Maths question: if the mean of seven numbers is 10. If six of the numbers are 2,4,8,14,16 and 18. Find the mean (A)8 (B)6 (C)2 (D)14

Do u mean d last number.
If yes,then it's 8.

Divsy: Bio..d ciliates often display an sexual phenomenon called?(a)conjugation,(b)asexual reproductn,(c)binary fission,(d)parthenogenesis
2.d process by which information is copied frm DNA 2 RNA Is?(a)translation,(b)transcription,(c)transgression,(d)translocation
3.segmental,serial repitition of structures within an animal is known as...(a).comensalaism..(b).mesmerism..(c).gastrutatn.(d.)anaphylaxis
4.a group of geneticaly identical individuals is called a...(a)cohort,(b)herd,(c)clone,(d)pack

1. Conjugation.
2. Transcription.
3. I guess gastrutation
4. Clone

Collee: i guess the answer to be methylcyanide

U tried but dat was d former name(old name).

Aidy97: Methyl cyanide; CH3-methyl, CN-cyanide.
Anoda name is ethanonitrile
Ethano from the two C's and three H's dt is C2H3 and nitrile from N

You are correct, the IUPAC name is ethanonitrile

What is the IUPAC name of this compound?
CH3CN

Goallllllllllll!!!!!!!!!!!!!

I have seen it..Nigeria won.

Yungmilio2: General Questions...
