Many people  are always victims of industrially manufactured Viagra. Several deaths have been reported as a result of Viagra (sildenafil). However, these deaths can be avoided by using organically made Viagra or food we eat every day. There are some food substances which can help those people who are suffering from   erectile dysfunction than opting for the sildenafil use. This post addresses how sildenafil is processed, how it functions in the human body, how to make Viagra using watermelon and lemon. It helps those who are suffering from erectile dysfunction to deeply comprehend what they are using to avoid adverse effects of sildenafil. Sildenafil processing The synthesis of the  sildenafil commences with the methylation of hot dimethyl sulfate with the 3-propylrazole-5-carboxylic acid ester. Aqueous sodium hydroxide (NaOH) is added to the mixture to free the acids, a process known as the hydrolysis. Oleum or fuming nitric acid is added to the produced product (th

Ammonia is synthesized from nitrogen gas and hydrogen gas in the Haber Process . The equation for its production is given by;  The forward reaction is exothermic, so, according to the Le Chatelier's Principle  low temperature will favor forward reaction. But Lower temperatures decrease the reaction rates and for maximum yield of ammonia, temperatures between 380 and 450-degree centigrade are used.    Recommendation:   Writelearnearn When you are provided with the following data and you are required to plot a graph of temperature versus equilibrium. Describe the shape of the graph for ammonia production.  What can you predict from the graph? From the graph, as the temperature increases, the equilibrium drops abruptly according to the Van’t Hoff Equation. Van’t Hoff equation is an equation that shows the relationship among the temperature (T), equilibrium constant (Kq) changes and particular change in standard enthalpy. The catalyst used in the pr
