We are currently struggling to cover the operational costs of Xtremepapers, as a result we might have to shut this website down. Please donate if we have helped you and help make a difference in other students' lives!

Its B, since yellow ppt is formed by silver iodide.Need helpView attachment 63782
If you find the ratio of salt to sulphite( simply by finding moles of salt and sulphite according to the info given) it comes out to be 2:1
& the equation shows 1 mole of sulphite looses 2 electron, therefore 2 mol of metallic salt gain those 2 electrons or 1 mol of metallic salt gains 1 mol of electron
therefore new O.N. of metal = +3-1=+2!

can someone help me with this question?
It says salt formation so the ratio of acid to calcium would be 2:1 for example for Butanedioic acid seperate into two parts and react it with calicum and it will look like this :View attachment 63791
I really can't figure this out. How can the formula be like that? Isn't it going to be 2 Ca ? The answer is C btw. Helppp
Thank youuuuuIt says salt formation so the ratio of acid to calcium would be 2:1 for example for Butanedioic acid seperate into two parts and react it with calicum and it will look like this :
CH2COO- + Ca2+ = (CH2COO)2 Ca
And do that for the rest and so its formula will become
C8H8O8Ca2
Divide by 2 and so the E.F becomes
C4H4O4Ca
As the reactants react they produce auto catalyst with the products so the rate increases but later after some time the the rate will decrease due to low substrate concentration.why is it C and not B?
is shape of graph B for conc against time for auto-catalytic reaction?As the reactants react they produce auto catalyst with the products so the rate increases but later after some time the the rate will decrease due to low substrate concentration.
How to do this one?
PV/RT=n where n is moles of CO2 produced..with calculation u ll get n=16How to do this one?
ThanksPV/RT=n where n is moles of CO2 produced..with calculation u ll get n=16
since 2 moles of alkane are producing 16 moles of CO2,
alkane : C02
1 : 8
means alkane has 8 carbons in it
Help needed hereThe answer to this is C...although I know that there will be no dipole moment in CO2 but does that also mean that it will not have permanent dipole-dipole interactions?
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.
