Esterwhats ethyl ethanoate?...
Its an ester made from the combination of alcohol ethanol and carboxylic acid ethanoic acidwhats ethyl ethanoate?...
tubes III, IV,V.
Must be Zinc because N displaced Copper but not Magnesium, so it must be less reactive than Mg, but more reactive than Cu.
displacement reaction. fact.
ZnCO3 will decompose to ZnO and CO2
One mole of compound X gives three moles of ions in aqueous solution. Sulfuric acidis H2SO4 and one mole of sulfuric acid can give off twoOne mole of compound X gives three moles of ions in aqueous solution. X reacts with ammonium carbonate to give an acidic gas.
What is compound X?
A Calcium Hydroxide
B Ethanoic Acid
C Sodium Hydroxide
D Sulfuric Acid
~~~~~~~~~~~
I know the answer is D. Sulfuric acid. What I would like to know is why.
structure mei yeh wala hoga tou hi baney gey acid ! syed1995Didn't get this, mind explaining?
changing volume doesnt effect rate of reaction!Hey can anyone tell me,What will happen to the rate of reaction when the VOLUME is increased or decreased.Plz reply fast.
Link please.help in atp paper june 2008 question 11 .. pls asap !!!!!
no! if volume of water is added, only then the concentration would change!! the concentration would not change if HCl is added to HCl!!volume and concentration are inversely proportional!!
dude thats simple logic...:|no! if volume of water is added, only then the concentration would change!! the concentration would not change if HCl is added to HCl!!
is your CAPSLOCK stuck dude??MASS OF PURE SUBSTANCE/MASS OF TOTAL SAMPLE *100
Link please.
Btw, have some doubt on the "test of sulphate"
LMAO, ure right, stupid mistake i did there.no! if volume of water is added, only then the concentration would change!! the concentration would not change if HCl is added to HCl!!
but increasing volume, eg using 20 cm^3 instead of 10cm^3 of HCl wont change the rate! that is waht they were discussing before ur post!dude thats simple logic...:|
everyone knows that..:|
sulphate ions or gas?Link please.
Btw, have some doubt on the "test of sulphate"
B(i) hydrogenatp paper june 2008 question 3 b i , bii
Aluminium Oxidewat r the catalysts that r used in cracking of hydrocarbons?specially the ones used in the apparatus where there is this tube in which there is a cotton plug soaked in hydrocarbon oil leading to a tube that hv a catalyst nd then ethene is collected abv a water tank in a test tube.
