Gravimetric analysis of a petrol sample was 85.5% Carbon, 14.5% Hydrogen. The analysis of the dry product gave 14% CO2, some O2 and reminder N2.
- Calculate the air to fuel (A/F) ratio supplied to the engine.
- The mixture strength (equivalence ratio).Determine if condensation occurs if the final product temperature and pressure are 20oC and 1.013 bar respectively.

The gravimetric analysis of iron in an ore sample was performed
by digesting the sample in strong acid, followed by precipitation
of Fe(OH)3 using KOH, filtration of the crystalline iron hydroxide,
and finally drying and ignition at high temperature to produce
Fe2O3. After cooling in a dessicator, two different students got
the following replicate results:
Student 1, Trial 1 – 0.2109 g of ore results in 0.04594 g iron
(III) oxide
Student 1, Trial 2 – 0.2110 g of ore...

Make an estimate of the composition of carbon, hydrogen,
oxygen, and nitrogen in the dry mass of a bacterium. Using
knowledge of the size and mass of a bacterium, the fraction of that
mass that is "dry mass" (that is, ca. 30%) and the chemical
constituents of a cell, figure out the approximate small integers
(< 10) for the composition CmHnOpNq, that is, find m, n, p, and
q.

Dry
Coke composed of 4% inert solids (ash), 90% carbon, and 6% hydrogen
at 40C is burned in a furnace with dry air at 40C. The solid refuse
at 200C that leaves the furnace contains 10% carbon and 90% inert,
and no hydrogen. The ash does not react. Analysis of the flue gas
which is 1100C gave 13.9% carbon dioxide, 0.8% carbon monoxide,
4.3% oxygen, and 81.0% nitrogen. There is also a third exit stream
which is a superheated steam...

An organic compound contains carbon, hydrogen, and sulfur. A
sample of it with a mass of 2.712 g was burned in oxygen to give
gaseous CO2, H2O, and SO2. These
gases were passed through 311.2 mL of an acidified 0.0200
M KMnO4 solution, which caused the
SO2 to be oxidized to SO42-. Only
part of the available KMnO4 was reduced to
Mn2+. Next, 31.12 mL of 0.0300 M
SnCl2 was added to 31.12 mL portion of this solution,
which still...
