Answer:
1) 18.91 mL
2) 2.35 %
Explanation:
1. The volume of base that was required is equal to the <em>difference between the reading at the end of the titration and the reading at the beginning</em>:
- V = 20.95 mL - 2.04 mL = 18.91 mL
2. The mass percent can be written as:
- Mass Percent = Mass solute / Total mass * 100%
For this problem:
We<u> input the data and calculate the mass percent</u>:
- % mass = 2.28/96.92 * 100% = 2.35 %
Answer:
CO2
Explanation:
They share 2 electrons with carbon.
the mixture can contain more or less iron, but iron sulfide always contains equal amounts of iron and sulphur.
the iron and sulphur atoms are not joined together in the mixture, but they are joined together in iron sulfide.
Ummmm this one is hard but i guess it would be t?????
