III. Suppose a substance has been prepared that is composed of carbon, hydrogen, and nitrogen. When 0.1156 gram of this compound is reacted with oxygen, 0.1638 gram of carbon dioxide (CO2) and 0.1676 gram of water (H2O) are collected. If all the carbon in the compound is converted to CO2

1. Determine the mass of Carbon and hydrogen in the sample

**What is difference of pH (рН) between matrix and periplasmic space of

mitochondria:

you synthesised a sample of tetramethyl-ammonium tri-iodide, the melting point deviates from the idea melting point for tetramethyl-ammonium tri-iodide which is 117 degree C. This suggest that the sample maybe impure.

the sample contains: C - 10.56%, H - 2.66%, N - 3.08%. How many iodine atoms does your sample have according to this analysis!?

Salt hydrolysis is a reaction in which one of the ions from a salt reacts with water, forming either an acidic or basic solution. Using the following titration set-ups explain how the salt formed would affect the end-point pH.

Provide equations to support your discussions.

a. HCl and NaOH

b. HCl and NH3

c. CH3COOH and NaOH
