What is electronic configuration of atoms of elements?

Electronic configuration of atoms of elements is the arrangement of electrons in the electron shells or orbitals in atom.

The  electronic configuration of an atom depends on the atomic number of the element.

The atomic number of nitrogen is 7. This means that it has seven electrons in its orbitals.

The electronic configuration that matches that of the nitrogen atom is 1s²2s²2p³.

What reaction conditions most effectively conver a cabocxylic acid to a methly ester?

Answers

Answer:

Esterification reaction

Explanation:

When we have to go from an acid to an ester we can use the esterification reaction. On this reaction, an alcohol reacts with a carboxylic acid on acid medium to produce an ester and water. (See figure).  

In this case, we need the methyl ester, therefore we have to choose the appropriate alcohol, so we have to use the methanol as reactive if we have to produce the methyl ester.

Can I+ (the iodine cation) becalled a Lewis base?
Fullyexlplain your answer.

Answers

Answer: No I+ cannot be called a Lewis base.

Explanation:

According to Lewis Theory, it defines an acid as an electron-pair acceptor and a base as an electron-pair donor.

In terms of Lewis basicity, Iodide ion (anions) has the more readily available lone pair electrons for donation since iodide ion is less electronegative .

With the help of the net electronic structure one can understand the answer of the question, because we need to study the I+  ion (cation) structure.

Lewis acid is therefore any substance, that can accept a pair of nonbonding electrons. 

From the picture below I+ is most likely ready to accept electrons not to give from it 5s orbital to become stable.

Isn't this false? For the industrial production of indigo carmine, a blue food colouring additive, a synthetic process with an E-factor of 17.4 produces less waste than a synthetic process with an E-factor of 3.0.

The answer I got was False, is this correct?

Answers

Answer: yes it is false

Explanation:

The statement is false. A synthetic process with a lower E-factor produces less waste than a process with a higher E-factor.

The E-factor is a measure of the waste generated during a manufacturing process. It is calculated by dividing the total mass of waste produced by the mass of the desired product. A lower E-factor indicates that less waste is generated per unit of product.

In this case, the synthetic process with an E-factor of 3.0 produces less waste than the process with an E-factor of 17.4. This means that the process with an E-factor of 3.0 is more efficient in terms of waste reduction.

A compound is found to contain 18.28 % phosphorus , 18.93 % sulfur , and 62.78 % chlorine by mass. To answer the question, enter the elements in the order presented above. QUESTION 1: The empirical formula for this compound is . QUESTION 2: The molar mass for this compound is 169.4 g/mol. The molecular formula for this compound is

Answers

Answer:

1. EF = PSCl₃; 2. MF = PSCl₃  

Explanation:

1. Empirical formula

The empirical formula is the simplest whole-number ratio of atoms in a compound.

The ratio of atoms is the same as the ratio of moles.

So, our first job is to calculate the molar ratio of P:S:Cl.

Assume 100 g of the compound.

(a) Calculate the mass of each element.

Then we have 18.28 g P, 18.93 g S, and 67.28 g Cl.

(b) Calculate the moles of each element

\text{Moles of P} = \text{18.28 g C} * \frac{\text{1 mol P}}{\text{30.97 g P}} = \text{0.5902 mol P}\n\n\text{Moles of S} = \text{18.93 g S} * \frac{\text{1 mol S}}{\text{32.06 g S }} = \text{0.5905 mol S}\n\n\text{Moles of Cl} = \text{62.78 g Cl} * \frac{\text{1 mol Cl}}{\text{35.45 g Cl }} = \text{1.771 mol Cl}

(c) Calculate the molar ratio of the elements

Divide each number by the smallest number of moles

P:S:Cl = 0.5902:0.5905:1.898 = 1:1.000:3.000 ≈ 1:1:3

(d) Write the empirical formula

EF = PSCl₃

The empirical formula for this compound is PSCl₃.

2. Molecular formula

(a) Calculate the ratio of the molecular and empirical formula masses

n = (169.4 u)/(169.40 u) = 1.000 ≈ 1

(b) Calculate the molecular formula

MF = (EF)ₙ = (EF)₁ = PSCl₃

The molecular formula for this compound is PSCl₃.

The empirical formula of the compound is PSCl₃.

To find the empirical formula, we first need to find the moles of each element in the compound. We can do this by dividing the mass of each element by its molar mass. The molar masses of the elements are:

P = 30.97 g/mol

S = 32.06 g/mol

Cl = 35.45 g/mol

The mass percentages given are for 100 g of the compound. So, the mass of each element in 100 g of the compound is:

P = 18.28 g

S = 18.93 g

Cl = 62.78 g

The moles of each element are then:

P = 18.28 g / 30.97 g/mol = 0.590 mol

S = 18.93 g / 32.06 g/mol = 0.590 mol

Cl = 62.78 g / 35.45 g/mol = 1.770 mol

The smallest whole number ratio of the moles of each element is 1:1:3. So, the empirical formula of the compound is PSCl3.

The molecular formula of the compound can be the same as the empirical formula, or it can be a multiple of the empirical formula. The molecular formula is not given, so we cannot say for sure what it is. However, we can say that the molecular formula must be a whole number multiple of the empirical formula PSCl3.

A protein is Select one: a. a saturated ester of glycerol. b. a polysaccharide. c. an aromatic hydrocarbon. d. a polymer of amino acids. e. one of the units making up a nucleic acid.

Answers

Answer:

d. a polymer of amino acids

Explanation:

Got it right on the test.

Answer:

D

Explanation:

The building blocks or monomers of proteins are called amino acids. There are 20 different kinds of amino acids. The amino acids form long chains that are proteins. Therefore, proteins are polymers of amino acids.

Proteins are very important for the body because they have many different roles. They provide structure for tissues, act as enzymes, hormones and antibodies, aid in transportation and fluid regulation.

Therefore, the correct answer is D. a polymer of amino acids.
