Re: what is the fuel-oxygen ratio

You need 1 mol of the given organic compound and 6 mol of oxygen according the equation. This gives a Ratio 1:6.

Re: Precipitation Help

Magnesium and sodium exchange each other. So get magnesium phosphate and sodium sulfate.
Now its your work.

Re: Difference between beryllium and aluminium

Check the specific gravity. If both peace same volume then you can weight it. Chemical analyses are more complicated and Beryllium is very poisson and carcinogen better don't touch it or work with. It.

Re: Mercury porosimetry

I think you have to calculate each dP and dV and draw it as function.
200- 50 = 150 and 0,142-0,085 = 0,057
500- 200 = 300 and 0,251 -0,142 = 0,109
and so one

Re: Acids and bases (dissociation of citric acid)

No, the basic reaction is R-COOH => R-COO- + H+
This you have to develop 3 times.

Re: Making Sodium Chorite from NaCl Solution and Electrolysis

First sodium chlorite is not possible to obtain by electrolysis. What you get is sodium hypochlorite NaClO. The procedure in your link will give this not sodiumchlorite. It is a mistake there. In this environment Peroxide will not developed. The chlorine can be absorbet by caustic soda I mentioned a...

Re: Making Sodium Chorite from NaCl Solution and Electrolysis

Important is to stirr very good. Why? You will not develop ClO2 that is different from ClO2-. The right electrode material is important. No blended carbon. It has to be pure graphite. The other things already mentioned, like voltage and current,concentration, etc. Also addition of baking soda or cau...

Re: Writing Double DIsplacement reactions

Manganese VII sulfide is not existing. Manganese-VII is only available as oxides or as anion in Permanganate.

But theoretically a equation can be formed.

Write down the formulas first.
