A qualitative data essentially provides the outcome of an experiment in a descriptive manner. It cannot be measured but can only be observed. For example: color of a solution, texture of a metal etc.
In contrast, a quantitative data provides a numeric value to explain the outcome of an experiment. It can be measured using appropriate tools. The data can be analysed through graphs to model the behaviour of a certain experiment or to predict an outcome. For example: temperature, volume, weight are all quantitative data. In reaction kinetics for example, the change in concentration of reactants is monitored as a function of time. Both, concentration and time are quantitative data and can be plotted to deduce the order of a reaction.
Convert Mg to grams 1g =1000mg what about 3.91 Mg = 3.91mg x 1g/1000mg= 3.91 x10^-3 g moles= mass/molar mass that is 3.91 x10^-3g /99 g/mol=3.95 x10^-5moles concentration= moles / vol in liters
that is 3.95 x10^-5/100 x1000= 3.94 x10^-4M
equation for dissociation of CUCl= CUCl----> CU^+ +Cl^-
Ksp=(CU+)(CI-) that is (3.95 x10^-4)(3.95 x10^-4) Ksp= 1.56 x10^-7
The sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun's core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom. During the fusion process, radiant energy is released.
