Forests are one of the most important natural resources that have been gifted to mankind for its sustained existence on earth. Conservation of forests is therefore a necessity that requires to be addressed as a priority. Forests provide us with huge amounts of tangible and intangible benefits‚ without which human existence would be threatened. Hence‚ for the survival of human beings‚ a holistic approach is required to be adopted towards a sustainable way to maintain our forests and meet our needs

Prepare information for parents / carers whose five year old child has head lice. Dear Parents‚ We at Mrinal’s Childcare have decided as a precautionary measure to prevent the outbreak of head lice among children. We have compiled some information on the subject to help you if your child or children already suffer from the same or to prevent your child from getting it. This is in no way meant to scare or offend anyone but is just a routine check that we follow on our facility. What are

observed that with increasing the dissolved oxygen content of the pulp‚ the pulp pH decreased considerably and the pulp Eh changed from a reducing to more oxidizing value. These changes in pH and Eh of the pulp were found to be favorable for the pyrite oxidation and the oxygen consumption. Therefore‚ Owusu et al. concluded that with increasing aeration time‚ the formation of the iron oxy-hydroxide species and also coating the surface with these species increase. Then‚ however‚ because of the coverage of

an iron (II) salt (ammonium iron (II) sulphate) Introduction Oxidation numbers describe the number of electrons the atom will gain or lose during a reaction. Each atom in an equation can be assigned an oxidation number according to certain rules. If the oxidation number of an atom increases as you go from the left side to the right side if an equation‚ oxidation has occurred (electrons have been lost); if the oxidation number decreases‚ reduction has occurred (electrons have been gained)

electrons an atom has and to determine where these atoms will go during a redox reaction‚ we can use oxidation numbers to determine this. The following guidelines can be used to determine the oxidation state of an atom or molecule. 1) Atoms in their pure elemental state (neutral) will have an oxidation number of zero‚ this is because the element has neither been oxidized or reduced. 2) The sum of the oxidation state of all atoms in an ion is equal the charge on the ion. The ionic charge of an atom can

metabolism usually inactivates drugs though some drug metabolites are pharmacologically in active status. Inactive substance which has a metabolite that is active is referred to as a prodrug. Drugs are metabolized by the following processes; reduction‚ oxidation‚ conjugation‚ hydration‚ hydrolysis‚ condensation and isomerization. All these processes make the excretion of drugs easier from the body like that of a human being. For metabolism to occur‚ enzymes must be present. Enzymes are present in body tissues

partner and I were to conduct an experiment about the oxidation rate of the enzyme peroxidase in the presence of its substrate guiacol. Also we used other substrates‚ such as hydroxylamine an enzyme inhibitor‚ to observe the weather the reaction rate was slowed down‚ sped up‚ or stopped reactions all together. These results were recorded by taking the materials in a test tube‚ then inserting them into a spectrophotometer to record the oxidation (intensity of color change from clear to reddish-brown)

red. Does anyone know which functional group would be present in solution? Potassium Magante is K2MnO4 whereas the permanganate is KMnO4‚ in the second one the Mn as a higher oxidation state of +7‚ the other one just +6. It would show that a double bond is present. (It oxides the alkene to a diol‚ which changes the oxidation state of the Mn changing it’s colour) Original post by GyasiW) First of all I would like to know the differences in formulae between Potassium Mangante and Potassium Permanganate
