Re: Chemical equilibrium composition

You have ammonia and methane on educt side already why you should have it on product side again. What kind of process is it. At least you can make from 1 mole methane 2 mole hydrogen and 1 mole carbon. Ammonia can be decomposed in the back reaction of Haber Bosch 2 mole ammonia give 1 mole nitrogen ...

Re: BALANCE CHEMICAL EQUATIONS

Acid + Base gives salt + water. So it depends how much from each is added what happend. Like KOH + H3PO4 you can have 3 different results. KH2PO4, K2HPO4 and K3PO4. Ammonia gives Ammonium NH4+ Urea decompose with acids to ammonia and carbondioxide. Salt1 + acid1 gives Salt2 + acid2, in solution you ...

Re: Acid-Base Titrations

It means HInd. => H+ + Ind.- if 10% is on the right side its colourless, if the dissociation is 90 % then its yellow.
It is a change from 10 Ind.- to 90 HInd. to 90Ind.- to 10 HInd.

Re: Mineral oil/Alkalis

What do you mean with alkali storage. Mineral oil is a mixture of carbonhydogen compounds. Depending the area USA Arabia northsea, etc. the mixture is different.
