Describe the conditions favorable to the growth of bacteria in food. Bacteria are everywhere. Some are beneficial, such as those used to make fermented dairy and meat products. Others cause spoilage. And, a small percentage are harmful or pathogenic.
Classically, chemical reactions encompass changes that only involve the positions of electrons in the forming and breaking of chemical bonds between atoms, with no change to the nuclei (no change to the elements present), and can often be described by a chemical equation.n the BroenstedâBrÃ¸nsted lowryâacid base, theory an-acid base reaction involves a transfer of (Protons +) h from one (species the) acid to (another the). Base when a proton is removed from an, acid the resulting species is termed that'acid s conjugate. base
A reversible reaction is a chemical reaction where the reactants form products that, in turn, react together to give the reactants back. Reversible reactions will reach an equilibrium point where the concentrations of the reactants and products will no longer change. A reversible reaction is denoted by a double arrow pointing both directions in a chemical equation. For example, a two reagent, two product equation would be written as. A + B â C + D.
