A major component of gasoline is octane (C8H18). When octane is burned in air, it chemically reacts with oxygen gas (O2) to prod

uce carbon dioxide CO2 and water H2O. What mass of carbon dioxide is produced by the reaction of 7.58 g of octane? Please explain the answer to me like I'm five, I want to understand but the content makes no sense.

Answer:

Mass = 23.232 g

Explanation:

Given data:

Mass of C₈H₁₈ = 7.58 g

Mass of CO₂ produced = ?

Solution:

Chemical equation:

2C₈H₁₈ + 25O₂      →     16CO₂ + 18H₂O

Number of moles of octane:

Number of  moles =  mass/molar mass

Number of moles = 7.58 g/ 114.23 g/mol

Number of moles = 0.066 mol

Now we will compare the moles of CO₂ with octane from balance chemical equation.

                  C₈H₁₈            :           CO₂

                       2              :              16

                 0.066             :           16/2×0.066 = 0.528

Mass of CO₂ produced:

Mass = number of moles × molar mass

Mass = 0.528 mol × 44 g/mol

Mass = 23.232 g

Please help: How do oxidation reactions help people with diabetes monitor their blood glucose levels? Thank you!!!
solong [7]

Answer:-

People with diabetes must monitor their blood glucose levels constantly.

Blood glucose levels are nowadays measured by the help of enzyme glucose oxidase. The enzyme glucose oxidase catalyzes the oxidation of glucose to gluconic acid.

By this way all of the glucose is measured at one time. At the same time hydrogen peroxide is produced.

The hydrogen peroxide reacts with a second color producing chemical. The concentration of the glucose can be related to the intensity of color produced

Use the pop-up menus to label the following statements as either True of False.
goldenfox [79]

Answer:

1 True

2. True

3. True

4. True

5. False

Explanation:

1. Hypochlorous acid (HOCl)  is a weak acid that forms when chlorine dissolves in water, and is partially dissociated, forming hypochlorite. HOCl is considered a strong oxidizing agent responsible for the killing action of germs in chlorine solutions.

2. Acetic acid is also known as ethanoic acid. It has a distinctive sour taste and pungent smell, and is generally considered a weak acid. in a concentrated form, acetic acid can be corrosive.

3/4 . Methylene chloride is an organochloride compound with the formula CH2Cl2. It is  a colorless, volatile liquid with a moderately sweet aroma is widely used as a solvent. It is normally stable, non-flammable and non-explosive when mixed with air at temperatures below 100 °C, but its vapor is flammable only when present in relatively high concentrations of about 14% to 22% in air. Research shows that it is very much possibly carcinogenic, and it has been linked to cancer of the lungs, liver, pancreas, breast cancer and salivary gland cancer in laboratory animals.

5. Laboratory and medical waste are not to be disposed in the trash with regular wastes, as they are potentially toxic. Special disposal methods and agencies exists to take away such wastes.

satela [25.4K]
<span>after the 1940, the infention of : PASTEURIZATION permitted wines to be produced in places where climate was not ideal for wine production after pasteurization process, all the microbes that exist within the wine are eliminated, which will prevent it from rottening. This make it possible to store wine for a long period of time even thought it's not in the harvesting climate</span>

Answer:

- Nucleus Function - Controls and regulates the activity of the cell.

- Ribosome builds proteins.

- A vesicle structure is kinda like a sac filled with a fluid of sorts.

- Rough ER has ribosomes attached to the cytoplasmic side of the membrane.

- Golgi apparatus kinda looks like a "stack of peta bread"

- Golgi apparatus functions as a factory in which proteins received from the ER are further processed and sorted for transport to their eventual destinations

The cytoskeleton of a cell is made up of microtubules, actin filaments, and intermediate filaments.

- The smooth endoplasmic reticulum functions in many metabolic processes. It synthesizes lipids, phospholipids as in plasma membranes, and steroids.

- The mitochondria produced energy/ATP

- Mitochondria have a double membrane arrangement that separates the organelle into four distinct compartments

- The cytosol contains an organized framework of fibrous molecules that constitute the cytoskeleton
