Yeah lol you should tell your teacher!! but one typo in my answer i should have said your book isn't wrong lol since they just ingore water but the reaction proceeds in the similar way .. sorry !!

at equivalence point you always have:
C1V1= C2 V2 (C concentration and V volume)
therefore,
250mL x 0.1M KHPht = 23.73mL x C2 NaOH.
note you dunt hv to convert the volume into L or anything since there are same units of ml on both sides so they will cancel out anywayss
hope that helps..

It should look something like this, rather than what u've suggested:
2 KMnO4 + 3 H2SO4 + 5 H2O2 = K2SO4 + 2MnSO4 + 8H2O +5O2

hope that helps

Hey there you go states do tell you something about the nature of the reaction since H2SO4 is aquous, There is WATER present in the reaction means it is dissolved in water to make it aqueous so your reaction looks something like: Na2B4O7 + H2SO4 +5H2O => 4H3BO3 + Na2SO4 Your book isnt correct becaus...

Hye just type in "preparation of cyclohexane from cyclohexanol" in google they give you several methods to prepare cyclohexENE from cyclohexanol. So i would say follow that procedure and in the end when you have cyclohexene, do the hydrogenation reaction, adding H2 Gas in the presence of a...

i guess it shud be 3-bromo-2,4 di methylhexane so you just have 6 carbon chain where you have methyl (CH3) on carbon number 2 and 4 and a bromo group on 3 carbon and thats it i guess.. That wud be a simple structural formula if you represnt the Carbon atoms in chain but if you want skeltal formula t...

welll there are so many places to find if specifically looking for enthaply of formation you can find here http://en.wikipedia.org/wiki/Enthalpy or just type like change in enthaply of (formation or solution or neutralization.. etc etc..) in google and im pretty sure you will find it... hope that wu...

1) What is the mass in grams of 14.82 L of NH3 at10.0 degrees Celcius and 560 mm HG? Answer: use PV =nRT where P is 560mm Hg or (560/760)atm Use R = .082 Latm/ K mol Volume is 14.82 L T is 273 + 10 C=283 K, and find n when you are done finding n which is number of moles after finding n, say moles n ...

2 C6H6 + 15 O2 = 12 CO2 + 6 H2O umm this is the balanced equation so it is clear that 2 moles of C6H6 gives 12 moles of CO2 so it means 1 mole of C6H6 gives 6 moles of CO2. Moles of C6H6 from 20 grams is= Moles= Mass/ Molercular Mass = 20/78 =.2564 moles of C6H6 as we said 1 mole of C6H6 gives 6 mol...

It should have been correct. I wonder why it is wrong. Just maybe few point like 1297 sumting in case you use exact molar masses but otherwise approximately you answer shud be correct, hmmmm weird!!

There are three isomers of C6H14O 1-Hexanol (OH at the first Carbon from either side of the 6 Carbon chain) 2-Hexanol (OH at the 2nd carbon from either side of the 6 Carbon chain) 3-Hexanol (OH at the 3rd carbon from either side of the 6 Carbon chain) CH3-CH2-CH2-CH2-CH2-CH2 OH JUST CHANGE AROUND TH...

I guess it should just be
3 H2 + N2 = 2 NH3
since nothiing is mentioned we could assume that nitrogen is derived from the air and also the only way to get NH3 as end product alone is the one we have mentioned.. so i gues follow that..
maybe it helps ..

Because CH3COOH is the formula for acetic acid and secondly the priduct is litle differnt. well here is wut you are supposed to be havingg
NaOH + CH3COOH = CH3COONa + H2O

hope it helps,

NaOH + KHC8H4O4 = KHC8H3O4Na + H2O

AlCl3 + 3 AgNO3 = 3 AgCl + Al(NO3)3


its AgCl
