give a balanced equation for the folowing:
1)methane burns in oxygen
2)sodium piece is added to water
3)barium chloride reacts with sodium sulphate
4)carbonmonoxide combines with hydrogen forrming methyle alcohol at apressure of 340 atmosphere

Sodium Fluoride is used in many types of toothpaste to give them basic pH. Sodium ions do not affect the pH of the solution. Prove that fluoride ions shift pH into basic range by finding pH of the 0.023mol/l solution of sodium fluoride.

Do you know how long it takes to do a lab report because my is due tomorrow and I do not know how long it will take them I gave it to them a day and a half ago.

A 50.00 mL solution of 0.0350 M hypochlorous acid (ka = 3.5 x 10^-5) is titrated with a 0.0105 M solution of NaOH as the titrant. What is the pH of the acid solution after 15.00 mL of titrant have been added?

A titration of 200.0 mL of 1.00 M H2A was done with 1.18 M NaOH. For the diprotic acid H2A, ka1 = 2.5 x 10^-5 and ka2 = 3.1 x 10^-9. Calculate the pH after 100.0 mL of 1.18 M NaOH have been added
