Draw a chiral aldehyde with the formula C3H5BrO.

You do not have to explicitly draw H atoms. In cases where there is more than one answer, just draw one.

Answers

Answer 1

The structure of chiral aldehyde with the formula C3H5BrO would have an aldehyde group at C1 atoms and Br attached to the terminal C atom of the chain.

An organic substance with a -CHO functional group is an aldehyde. We can start by drawing a linear chain with the substituents and then draw branched carbon chains at non-equivalent carbon atoms to create all the structures. According to the nomenclature rules for organic compounds, C3H5BrO can be named as 2-bromopropanal or 2-bromo-propionaldehyde. This compound will have an aldehyde group at C1 and a methyl group and a halide group attached to C2 atom of the chain.

Aldehydes are recognised as organic substances because they have a -CHO functional group. It has a carbonyl centre, which implies that a carbon atom will form a double bond with an oxygen atom and that the same carbon centre is joined to an alkyl group or additional hydrogen atoms.

How many carbon atoms are there in a 12.5 kg sample of carbon?
step by step solution

Answers

Answer:

6.27 X 10^26 atoms

Explanation:

Write down the formula:

number of moles = mass/Ar    (Ar is atomic mass)

Ar of carbon = 12

mass = 12.5kg or 12500g

Substitue these values into the formula:

number of moles = 12,500g / 12 = 3125/3 or 1041.6

Convert this to atoms:

1 mole = 6.022 X 10^23 atoms

So, 1041.6 moles = 6.27 X 10^26 atoms

The table below lists the naturally occurring isotopes of element X. Calculate the average atomic mass.

explain why a nanowire can be longer than 3000nm but still be considered a metallic nanomaterial​

Answers

Answer:

A nanowire is a nanostructure, with the diameter of the order of a nanometre (10−9 meters). It can also be defined as the ratio of the length to width being greater than 1000. Alternatively, nanowires can be defined as structures that have a thickness or diameter constrained to tens of nanometers or less and an unconstrained length. At these scales, quantum mechanical effects are important—which coined the term "quantum wires". Many different types of nanowires exist, including superconducting (e.g. YBCO[1]), metallic (e.g. Ni, Pt, Au, Ag), semiconducting (e.g. silicon nanowires (SiNWs), InP, GaN) and insulating (e.g. SiO2, TiO2). Molecular nanowires are composed of repeating molecular units either organic (e.g. DNA) or inorganic (e.g. Mo6S9−xIx).

Why is 1/t used as a measure of rate of reaction?​

Answers

1/t denotes that the reaction order is of the first order. That is, the rate of reaction is directly proportional to the concentration of the reactant. Because scientists use standard units, 1/t equals one divided by one second.

What do you mean by first order reaction ?

The term first order reaction is defined as a chemical reaction in which the reaction rate is linearly dependent on the concentration of only one reactant.

In other words, a first-order reaction is a chemical reaction in which the rate varies as the concentration of only one of the reactants changes.

Because a reaction that takes longer to complete is obviously a slower reaction. A fast reaction is one that takes less time to complete. 1/t simply provides a quantitative value for comparing reaction rates.

Thus, 1/t denotes that the reaction order is of the first order.

Answers

Answer:

7.28 mol Na2SO4

Explanation:

Since it is already in moles, all we have to do is use a molar ratio

A molar ratio is the proportions of reactants and products using the balanced equation. When writing a mole ratio, the given information must cross out with the right thing.

7.28 mol H2SO4 * 1 mol Na2SO4/1 H2SO4 = 7.28 mol Na2SO4

I will mark you brainiest if you can answer this Why might a person agree to become an indentured servant and work for no pay?to help you answer here's a source;Jamestown was settled in 1607. Over the years, it grew into a larger colony: the Virginia Colony. The Virginia colonists made their living by growing tobacco. It took a lot of workers to plant, take care of, and harvest this crop. Landowners forced enslaved Africans to do much of this work. The first Africans arrived in Virginia in 1619.Not all workers were slaves. Many were indentured servants. These were people who agreed to work for a certain number of years for no pay. In exchange, their employers paid for their voyage to the colony.In 1634, a new colony, called Maryland, began north of Virginia. Maryland was the dream of Sir George Calvert, Lord Baltimore. He wanted to found a colony where Catholics could practice their religion freely. At this time, Catholics in England were persecuted. Calverts son, Cecilius, worked to start the colony.Cecilius offered free land to settlers who would come to Maryland. Upper class Englishmen were given large amounts of land. Average colonists were given less land. As in Virginia, wealthy landowners used enslaved Africans and indentured servants to do the work.Before long, there were more Protestants than Catholics living in Maryland. To protect the Catholics religious freedom, the colony passed the Act of Toleration in 1649. However, the law did not end tension between the colonys Protestants and Catholics. Eventually Maryland named one Protestant church as the official church of Maryland.Other tensions arose over Marylands border with its northern neighbor, Pennsylvania. For many years, the two colonies argued over the exact location of the boundary between them. They finally agreed to settle the dispute once and for all. They hired Charles Mason and Jeremiah Dixon to map the border. This boundary became known as the Mason-Dixon line.Virginia also experienced troubles during this time. James Berkeley, the governor of Virginia, promised Native Americans that settlers would not go farther west into their lands. Nathaniel Bacon was a farmer in western Virginia. He did not like the promise Governor Berkeley had made. In fact, many people in western Virginia did not like it. The nitrogen base pattern determines how _____________ is replicated.
