There are three major hazards that may be introduced into the food supply any time during harvesting, processing, transporting, preparing, storing and serving food. These hazards may be microbiological, chemical or physical.

Explanation:

microbiological hazards

Microbiological hazard occurs when food becomes contaminated by microorganisms found in the air, food, water, soil, animals and the human body. Many microorganisms are helpful and necessary for life itself. However, given the right conditions, some microorganisms may cause a foodborne illness. Microorganisms commonly associated with foodborne illnesses include bacteria, viruses and parasites.chemical hazardsChemical hazards can occur at any point during harvesting, storage, preparation and service. When toxic chemicals used for pest control or for cleaning and sanitizing food contact surfaces and food preparation equipment come into contact with food, the food may be contaminated by those chemicals.Toxic metals such as copper, brass, cadmium, lead and zinc can be a source of chemical contamination. Zinc, used in galvanized containers (garbage cans) and in gray enamelware containers which may be plated with anatomy or cadmium, can make acidic foods such as orange juice or tomato sauce and pickles poisonous. Pottery dishes with lead glazes should not be used to prepare or serve food.Intentionally added chemicals help to maintain a food’s freshness or to enhance flavors in foods. Check the food ingredient label for more information about the additives. Excessive use of some additives has been linked (see Fact Sheets on Food Allergies and Food Additives) to cases of lethal allergic reactionsparticularly among sensitive individuals, in particular, asthmatics.Foodservice establishments are prohibited by law from using sulfites to maintain product freshness. However, they are still approved for use in some food processing operations, for example, processing shrimp and manufacturing wine. If they are used, the product must be clearly labeled.physical hazardsPhysical hazards usually result from accidental contamination and /or poor food handling practices. Examples include, slivers of glass, human hair, nails, false nails, nail polish, pieces of jewelry, metal fragments from worn or chipped utensils and containers, dirt, stones, frilled toothpicks.Pesticides may leave residues on fruits and vegetables. In general, these residues can be removed by scrubbing the surface and washing with water.Food irradiation is classified as a food additive and is regulated by the Food and Drug Administration (FDA). Irradiation is a process which destroys pathogenic and spoilage microorganisms without compromising safety, nutrition or quality and significantly lengthens storage life. In general, spices are irradiated as a means of controlling bacterial growth and mold. According to Dr. Donald Thayer of the USDA Agricultural Research Service, irradiation looks promising as a treatment for controlling cylospora in fresh produce like raspberries .

He chose pea plants because they were easy to grow, could be bred rapidly, and had several observable characteristics, like petal color and pea color.

Explanation:

Like charges repel each other, while opposite charges attract each other. This principle is one of the fundamental aspects of electrostatics. According to Coulomb's law, the force between two charged particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.

As the distance between two charged particles decreases, the force between them increases. This is because the closer the particles are, the stronger the electric field they create, leading to a stronger force of interaction.

On the other hand, as the magnitude of the charges decreases, the force between the particles also decreases. This is because the force is directly proportional to the product of the charges. If one or both of the charges are smaller, the force they exert on each other will be weaker.

In summary, according to Coulomb's law, decreasing the distance between charged particles increases the force between them, while decreasing the magnitude of the charges decreases the force. This understanding of the relationship between charge, distance, and force is crucial in explaining the behavior of charged particles and the interactions between them.

Answer:

definately substance A beacause its the lowest ph leval which means its more acidic

Explanation:

1. The reaction mixture with the largest amount of product(s) when at equilibrium is the one with the largest Keq value.

2. The reaction mixture with the largest amount of reactants when at equilibrium is the one with the smallest Keq value

3. The reactions in the table that have concentrations that represent the systems at equilibrium are Reactions 1 and 3.

4. For each reaction that is not at equilibrium, change the concentration of only one of the reactants or products so that the ratio represents the system at equilibrium.

1. In this case, the reaction mixture with the largest Keq value is Reaction 2. This is because the equilibrium constant, Keq, is a measure of the relative concentrations of the products and reactants at equilibrium. A large Keq value indicates that the equilibrium lies far to the right, meaning that there are more products than reactants at equilibrium.

2. The reaction mixture with the largest amount of reactants when at equilibrium is the one with the smallest Keq value. In this case, the reaction mixture with the smallest Keq value is Reaction 4. This is because a small Keq value indicates that the equilibrium lies far to the left, meaning that there are more reactants than products at equilibrium.

3. The reactions in the table that have concentrations that represent the systems at equilibrium are Reactions 1 and 3. This is because the concentrations of the products and reactants in these reactions are equal, which is the definition of equilibrium.

4. For each reaction that is not at equilibrium, change the concentration of only one of the reactants or products so that the ratio represents the system at equilibrium. For example, to bring Reaction 2 to equilibrium, we could increase the concentration of H2O or decrease the concentration of CO2.

Explanation:

1. The temperatures at which a substance changes phases indicate the relative strength of the forces between molecules in the substance.

2. solid, liquid, gas

3. The forces between water molecules break, and the bonds between the atoms in water are unchanged.

4. The forces strengthen, and the molecule structure becomes more rigid.

5. The intermolecular forces in ethanol are stronger than the intermolecular forces in acetone.

The the degree of intermolecular interaction between molecules determines the magnitude of boiling point of the substance.

During phase change, a substance moves from one state of matter to another. The temperature at which a phase change occurs is determined by the strength of the forces between molecules in the substance. The relative magnitude of intermolecular forces between molecules in different states of matter is solids > liquids > gases.

During boiling, energy is imparted to the molecules of a liquid. When this occurs, the forces between water molecules break, and the bonds between the atoms in water are unchanged.

We must recall that the molecules of a substance are in constant random motion. The average kinetic energy of molecules is proportional to temperature. As a sample of  calcium carbonate is cooled, the forces between molecules strengthen, and the molecule structure becomes more rigid.

The magnitude of intermolecular interaction affects the boiling point of a liquid. The stronger the magnitude of intermolecular interaction,the higher the boiling point. As such, ethanol having hydrogen bonds between its molecules has a higher boiling point than acetone which only posses weaker dipole - dipole interactions.
