Nutrition and Growth of Bacteria (page 4) (This chapter has 6 pages) Â© Kenneth Todar, PhD Physical and Environmental Requirements for Microbial Growth The procaryotes exist in nature under an enormous range of physical conditions such as O2 concentration, Hydrogen ion concentration (pH) and temperature.
In a double replacement reaction parts of two compounds switch places to form two new compounds. Two reactants yield two products. For example when silver nitrate combines with sodium chloride, two new compounds--silver chloride and sodium nitrate are formed because the sodium and silver switched places.
And synthesis substances combining Decomposition breaks down splits too Single replacement displace one in lieu In double, two ions switch places Single, single replacement one goes Less reactive moves from place It goes, it goes, where less reactive was held I know it will displace Replacement, replacement, double replacement Two compounds, the ions, switching places now One of the products of this one out Is often a gas or precipitate now Endothermic energy heat in Energy leaving exothermic And synthesis substances combining Decomposition breaks down splits too Single replacement displace one in lieu In double, two ions switch places Some combine synthesis reactions Substances combine make a single substance When one substance cancels another one out remember Neutralization zeros out properties and then when Breaking down, breaking down, simple substances Single substance breaks down, decomposition When heat is needed to break down compounds Thermal decomposition reaction
