<span><span>Implement a personal hygiene program. To lessen the possibility of food handlers contaminating food, institute a good personal hygiene program that includes policies addressing critical hand practices like proper handwashing, hand care and glove use. Also address staff cleanliness and work attire, focusing on topics such as bathing, clean clothing, the proper use of hair restraints and prohibited jewelry. Finally, policies should be put in place to make sure food handlers come to work healthy. Include actions such as reporting illnesses and covering wounds.</span><span>Remind employees to wash their hands. This is especially important after using the restroom and after handling raw meat, seafood and poultry. Once employees have washed their hands, ensure they use a single-use paper towel or hand dryer, rather than any part of their uniform, to dry. </span><span>Use separate equipment. Each type of food should be prepped and handled with a separate piece of equipment. For example, use one set of cutting boards, utensils and containers for raw poultry. Use another set for raw meat, and use a third set for produce. Some operations use colored cutting boards and utensil handles to help keep equipment separate. If this system is not possible at your restaurant, prep food at different times.</span><span>Clean and sanitize all work surfaces. All work surfaces, equipment and utensils should be cleaned and sanitized after each task. Simply rinsing equipment is not enough to eliminate pathogens that can contaminate food. </span><span>Purchase prepared food. You can prevent cross-contamination by purchasing food that doesn’t require much prepping. This minimizes handling and can reduce the transfer of pathogens from one surface or food to another.

The large number of areas covered by the chemical energetics can be explained by the different forms in which chemical energy can be released: heat and combustion work, electrical energy in electrochemistry, radiant energy in chemiluminescent systems.
The chemical energy provided by a reaction reflects the energy balance associated with the electronic modifications suffered by the species involved.
From an energy point of view, a chemical reaction between molecules can be schematized in two stages. The first requires a supply of energy and corresponds to the rupture of the bonds of the reactant molecules with release of the atoms which constitute them.
The second releases energy and concerns the creation, by recombination of these atoms, of new bonds entering the structure of the reaction molecules.
As a general rule, the energy released in the second stage is greater than the first. We are talking about exothermic reaction. The difference between these two energies (reaction enthalpy) measures the amount of chemical energy transferred to the external environment.
It is conceivable that this quantity translates, not only the number, but also the strength of the connections involved.
Arrow symbol →
Explanation:
The arrow symbol in a chemical equation separates the reactants from products.
A chemical reaction is process in which chemical changes leads to the formation of products from reactants.
The arrow symbol → is used to separate the reactants from products
⇆ shows reversibility of the reaction
↑ indicates that gas is given off as product

the controlled variables are, timing of adding ice, water used, and amount of sugar. the dependant variables are, daily temperature, and amount of lemon juice. the independent variable is, number of glasses sold. hope it helps
