Answer:

Simple sugars are a type of carbohydrate.

Explanation:

Carbohydrates are one of the three basic macronutrients — the other two being protein and fat. Simple sugars are found naturally in fruits and milk, or they can be produced commercially and added to foods to sweeten, prevent spoilage, or improve structure and texture.

What is the theoretical yield of fluorenone if you oxidize 175 mg of fluorene?

My name is Ann [436]

Answer:

602 mg of CO₂ and 94.8 mg of H₂O

Explanation:

The yield is measured by the amount of each product produced by the reaction.

The chemical formula of fluorene is C₁₃H₁₀, and its molar mass is 166.223 g/mol.

The oxidation, also know as combustion, of this hydrocarbon is represented by the following balanced chemical equation:

$2C_{13}H_{10}+31O_2\rightarrow 26CO_2+10H_2O$

To calculate the yield follow these steps:

1. Mole ratio

$2molC_{13}H_{10}:31molO_2:26molCO_2:10molH_2O$

2. Convert 175mg of fluorene to number of moles

$175mg/times 1g/1,000mg=0.175g$

Number of moles = mass in grams / molar mass

$\text{number of moles}=0.175g/166.223g/mol=0.0010528mol$

3. Set a proportion for each product of the reaction

a) For CO₂

i) number of moles

$2molC_{10}H_{13}/26molCO_2=0.0010528molC_{10}H{13}/x$

$x=0.0010528molC_{10}H_{13}\times 26molCO_2/2molC_{10}H_{13}=0.013686molCO_2$

ii) mass in grams

The molar mass of CO₂ is 44.01g/mol

mass = number of moles × molar mass

mass = 0.013686 moles × 44.01 g/mol = 0.602 g = 602mg

b) For H₂O

i) number of moles

$0.0010528molC_{10}H_{13}\times10molH_2O/2molC_{10}H_{13}=0.00526molH_2O$

ii) mass in grams

The molar mass of H₂O is 18.015g/mol

mass = number of moles × molar mass

mass = 0.00526 moles × 18.015 g/mol = 0.0948mg = 94.8 mg

The Andes Mountains are found along the western coast of South America. Which kind of plate boundary is responsible for this mou

lozanna [386]

The Nazca plate is converging with the South American plate.

Explanation:

The Andes Mountains are formed as a result of the convergent of the Nazca plate and the South American plate.

This mountain range typifies the geology and geography of the South American continent.

Along this convergent margin, one plate subducts beneath the other.
The oceanic plate due to its density goes into the mantle.
The causes the continent riding to obduct and be forced.
With rising magmatic bodies beneath, the continent further pushes up to form the Andes ranges.

An ionic bond occurs between what particles

kakasveta [241]

The correct answer is that an ionic bond forms between charged particles. To form this bond, the particles transfer valence electrons (those in the outermost orbit). Specifically, in ionic bonding, the metal atom loses its electrons (thus becoming positive) and the nonmetal atom gains electrons (thus becoming negative).

How much of the original amount of an isotope is present after a period of four half lives

vfiekz [6]

After 2 half-lives there will be 25% (1/4th) of the original isotope, and 75% (3/4 th) of the decay product

<h3>What is Half life period ?</h3>

A half life is a measurement of the slope of an exponential decay function.

It is also defined as, the time it takes to halve the concentration of something in a process.

Each half life you will have half of what you had at the beginning of a given half life.
