Glycolysis is the first phases of cellular respiration. In this phase, glucose is broken
down in the cytosol producing two molecules of pyruvate. The main pro
Electronic spectrum of iodine molecules
The major aim of the experiment was to observe the type of bands found in iodine molecule
using the spectrum in UV-Visible machine, to determine their nature of vibrat
Quinine Fluorescence Quenching
The lab analysis to be carried out was focusing on establishment of the decay kinetics
that are associated with quinine sulfate fluorescence in a solution of water and determi
What is Hard Water?
-Hard water is usually defined as water which contains a high concentration of calcium and magnesium ions.
Measurements of hardness are given in terms of the calcium carbonate equivalent, which is an expression of the
n is the quantum number (n= 1, 2, 3,.),L is the 'length' of the (one dimensional) molecular box, m is
the mass of the particle (electron), and h is Planck's constant.
E = hc

An empty 4.00 L steel vessel is filled with 1.013 bar CH4(g) and 4.053 bar O2(g) at 300
C. A spark causes the CH4 to burn completely according to the balanced equation:
CH4(g) + 2 O2(g) CO2(g) + 2H2O(g)rH = -802 kJ
What mass of CO2 is produced in the reac
What mass of butane, C4H10, would need to be combusted in order to convert 100.0 g of ice that
is initially at 0.0C to steam at 175.0C? Assume that all of the heat generated goes directly into
heating the ice. Enthalpy of combustion of gaseous butane is 2

ACIDS, BASES AND INDICATORS.
Generally acids are substances with a sour taste
The food we eat, some have a sour taste. The sour taste is due to the presence of acids.
Bases are substances with a bitter taste. Some foods we eat have a bitter t
