How many grams of KClO3 are needed to produce 6.75 Liters of O2 gas measured at 1.3 atm pressure and 298 K?

Answers

Answer 1

Answer

29.3171 g KClO₃

Procedure

To solve this question consider the following chemical reaction:

2KClO₃→2KCl+3O₂

Then we will use the ideal gas formula to determine the number of moles present in 6.75 L of oxygen gas.

Data:

V=6.75 L

T= 298 °K

P= 1.3 atm

R= 0.08206 L⋅atm⋅°K⁻¹⋅mol⁻¹

Equation

PV=nRT

Solve for n to get the moles

[tex]n=\frac{PV}{RT}=\frac{1.3\text{ atm }6.75\text{ L mol }\degree\text{K}}{0.08206\text{ L.atm 298}\degree\text{K}}=0.3588\text{ mol O}_2[/tex]

Use the stoichiometry of the reaction to convert from moles of oxygen to moles of KClO₃.

[tex]0.3588\text{ mol O}_2\frac{2\text{ mol KClO}_3}{3\text{ mol O}_2}=0.2392\text{ mol KClO}_3[/tex]

Finally, convert from moles to grams

[tex]0.2392\text{ mol KClO}_3\frac{122.55\text{ g KClO}_3\text{ }}{1\text{ mol KClO}_3}=\text{ 29.3171 g KClO}_3[/tex]

Answers

The volume of 79.1 liters of oxygen (O₂) will be produced at a temperature of 370°C and 1520 torr if 2 moles of KClO₃ decompose.

What is the molar volume of the gas?

The molar volume (Vm) is the volume occupied by 1 mole of a chemical element or a chemical compound at Standard Temperature and Pressure (STP). Molar gas volume is one mole at a specific temperature and pressure and has a fixed volume.

The Molar volume is inversely proportional to density and directly proportional to molar mass. One mole of any gas at STP occupies a volume of 22.4 liters.

Given, the 2moles of  KClO₃ will produce  O₂ gas = 3moles

The volume occupied by 3 moles of the oxygen gas at 370°C and 1520 torr is :

Given, n = 3, P = 1520 torr = 2atm and T = 370°C  = 643 K

PV = n RT

What is chemical contamination?
List what hazards it may cause for foods
Give at least 4 examples
List at least 5 procedures for preventing this type of contamination

Answers

Answer:

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 .

Answers

The dose of the medicine per one kilogram of a body is 2.5 mg then , the dose of medicine required for 66 lb weight or 29.8 Kg is 74.5 mg.

What is dose of a medicine?

Dose of a medicine is the amount of that medicine required to be taken for one time. It can be measured per Kg of body and the dose of medicine can be g or mg.

lb is a unit of weight. Generally we are using kilogram (Kg) unit of for kg. One lb weight = 0.453 kg.

Hence, 66 lb in kilogram weight is written as: 66 × 0.453 Kg = 29.8 Kg. The dose of medicine is 2.5 mg/kg which means, 2.5 mg is required for 1 Kg body.

The dose of the medicine required for 66 lb or 29.8 Kg is calculated by multiplying the dose required for 1 kg to the actual weight of the child as follows:

Dose =  29.8 × 2.5

         = 74.5 mg.

Thorium emits a beta particle is it a chemichal or nuclear reaction

Answers

Answer:

It is a nuclear reaction as Thorium here undergoes beta decay which is nuclear reaction

Explanation:

Beta decay occurs when an unstable nucleus emits a beta particle and energy. A beta particle is either an electron or a positron. Positron can be considered as an anti-electron as it has a positive charge unlike electrons. When the beta particle is an electron, the decay is called beta-minus decay. When the beta particle is a positron, the decay is called beta-plus decay. Beta-minus decay occurs when a nucleus has too many neutrons relative to protons, and beta-plus decay occurs when a nucleus has too few neutrons relative to protons. Thorium undergoes beta minus decay and produces Actinium and an electron.

Taking into account the reaction stoichiometry, 65.32 grams of B₂H₆ will react with 7.1 mol of O₂.

Reaction stoichiometry

In first place, the balanced reaction is:

B₂H₆ + 3 O₂ → B₂O₃ + 3 H₂O

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

B₂H₆: 1 moleO₂: 3 molesB₂O₃: 1 moleH₂O: 3 moles

The molar mass of the compounds is:

B₂H₆: 27.6 g/moleO₂: 32 g/moleB₂O₃: 69.6 g/moleH₂O: 18 g/mole

Then, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:

B₂H₆: 1 mole ×27.6 g/mole= 27.6 gramsO₂: 3 moles ×32 g/mole= 96 gramsB₂O₃: 1 mole ×69.6 g/mole= 69.6 gramsH₂O: 3 moles ×18 g/mole= 54 grams

Mass of B₂H₆ required

The following rule of three can be applied: If by reaction stoichiometry 3 moles of O₂ react with 27.6 grams of B₂H₆, 7.1 moles of O₂ react with how much mass of B₂H₆?

mass of B₂H₆= (7.1 moles of O₂× 27.6 grams of B₂H₆)÷ 3 moles of O₂

mass of B₂H₆= 65.32 grams

Finally, 65.32 grams of B₂H₆ is required.

Significance: The 14th Amendment overruled the Supreme Court decision in Dred Scott vs. Sanford and guaranteed that all persons born or naturalized in the United States are citizens of the United States and of the state in which they reside. The Amendment also guaranteed that all citizens would receive equal protection under the law. 1873 Slaughterhouse Cases These U.S. Supreme Court cases narrowly defined federal power in a way that made the 14th Amendment difficult to enforce. The Court's opinion asserted that most of the rights of citizens remain under state control.
