To wat time r u available today,sirHi, please do include the answers to your questions.
s07qp1
Q1. relative mass = 1/5 x 10 + 4/5 x 11 = 10.8
Q18. alkali gas is NH3. Fertiliser is NH4NO3. Empirical formula is N2H4O3
Q34. For mercury on right side to rise, the X flask create a higher pressure than before.
Statement 1: (True) Increase temp shift eqm right, more gases created, higher pressure created by X than N2 on right
Statement 2: (False) Increase temp shift eqm left, same amount of gases, same amount of pressure created in X compared to N2 on right.
Statement 3: (False) Both left and right experiences the same increase in pressure (just like statement 2).
No we are not ....... We are NOT enemies man ......And u should not be that much sensitiveI will try but i think this community has more harmony and peace without me.
This is so rude,But as u wish we will ignore uBro, let the dogs bark at the elephant.... Elephant will always swagger and poor dogs will bark...
U dont deserve that but i will answerWhen heated with chlorine, the hydrocarbon 2,2-dimethylbutane undergoes free radical
substitution.
In a propagation step the free radical X• is formed.
2,2-dimethylbutane + Cl● → X● + HCl
How many different forms of X• are possible?
A 1 B 2 C 3 D 4
When heated with chlorine, the hydrocarbon 2,2-dimethylbutane undergoes free radical2NaCl+2H2O----> Cl2+H2+ 2NaOH
Mr of NaCl=58.5
Mr of NaOH=40
Mr of Cl2=71
Mr of H2=2
Moles of NaCl=1
so moles of Cl2=0.5
H2 is 0.5
and
NaOH is 1
mass of Cl2=35.5
mass of H2=1
by now we know the answer is A
mass of NaOH is 40
Did I ask u???U dont deserve that but i will answer
Is the answer C??
Please get over itU dont deserve that but i will answer
Is the answer C??
The answer is C, As there are 3 possibilities 1. CH3* 2. CH3CH2* 3. CH* (All 3 CH3* are one possibility!)When heated with chlorine, the hydrocarbon 2,2-dimethylbutane undergoes free radical
substitution.
In a propagation step the free radical X• is formed.
2,2-dimethylbutane + Cl● → X● + HCl
How many different forms of X• are possible?
A 1 B 2 C 3 D 4
Shame on uDid I ask u???
wait a moment i am asnwering it. wait.Did I ask u???
??!!Please get over it
I gave Suchal Riaz an idiomatic exampleNo we are not ....... We are NOT enemies man ......And u should not be that much sensitive
PERSONALLY...I forgive u
and believe me mis understanding happened between all of us
This is so rude,But as u wish we will ignore u
U are not ma family member that u should have shame on me!!!Shame on u
U asked on this thread and i am a member here
Refer to : https://www.xtremepapers.com/community/threads/chemistry-post-your-doubts-here.9859/page-509
It is answered manwait a moment i am asnwering it. wait.
The answer would be C we can have CH3●When heated with chlorine, the hydrocarbon 2,2-dimethylbutane undergoes free radical
substitution.
In a propagation step the free radical X• is formed.
2,2-dimethylbutane + Cl● → X● + HCl
How many different forms of X• are possible?
A 1 B 2 C 3 D 4
RELAXI gave Suchal Riaz an idiomatic example
U are not ma family member that u should have shame on me!!!
LOYL! hahaI gave Suchal Riaz an idiomatic example
U are not ma family member that u should have shame on me!!!
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
