What is the limiting reagent and thus the mass of product for the reaction: P4O10 + 6H2O --> 4H3PO4 if 5.00 g of P4O10 react with 1.50 g of water?

1) Determine the moles of each reactant and thus the limiting reagent:# moles= mass (g)/M_{r .}M_r of P₄O₁₀ = (4 x 30.97) + (10 x 16.00) = 283.88 g mol

Describe how you could distinguish between ethanol, ethanoic acid, ethyl bromide and 2-methylpropan-1-ol.

First, you should add sodium hydrogen carbonate to all three compounds. Ethanoic acid will react with this to release a gas which will turn limewater cloudy.
Second, you should add acidified potassi...

Magnesium is in Group 2 of the Periodic Table. It has a number of naturally occurring isotopes, including 24Mg and 26Mg. (a) (i) Explain, in terms of the subatomic particles in the atoms, why 24Mg and 26Mg are isotopes.

Both isotopes of magnesium have 12 protons as shown by Mg's proton number in the periodic table.
By definition an isotope is an atom with the same number of protons but differs in its number of neutr...
