What is the concentration of kl solution if 20.68g of solute was added to enough water to form 100ml solution?

Chemistry
1 answer:
rewona [7]2 years ago
5 0

Answer:

1.25 M

Explanation:

Step 1: Given data

Mass of KI (solute): 20.68 g

Volume of the solution: 100 mL (0.100 L)

Step 2: Calculate the moles of solute

The molar mass of KI is 166.00 g/mol.

20.68 g × 1 mol/166.00 g = 0.1246 mol

Step 3: Calculate the molar concentration of KI

Molarity is equal to the moles of solute divided by the liters of solution.

M = 0.1246 mol/0.100 L= 1.25 M

The orbital filled by the last electron from the S element is 3p

<h3>Further explanation </h3>

In an atom there are levels of energy in the skin and sub skin.

This energy level is expressed in the form of electron configurations.

Writing electron configurations starts from the lowest to the highest sub-shell energy level. There are 4 sub skins in the skin of an atom, namely s, p, d and f. The maximum number of electrons for each sub skin is

• s: 2 electrons

• p: 6 electrons

• d: 10 electrons and

• f: 14 electrons

Charging electrons in the sub skin uses the following sequence:

<em>1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d¹⁰, 4p⁶, 5s², 4d¹⁰, 5p⁶, 6s², etc. </em>

Each sub-skin also has an orbital depicted in the form of a square in which there are electrons symbolized by half arrows.

Each orbital in an atom consists of 4 quantum numbers:

  • n is the principal quantum number.
  • l is the angular momentum / azimuthal quantum number
  • ml, the magnetic quantum number
  • ms, the electron-spin quantum number

Value of n: positive integer

value of l: s = 0, p = 1, d = 2, f = 3, ... (n-1)

ml value: between -l to + l

ms value: +1/2 or -1/2

An sulfur atom (S) has 16 electrons means having an electron configuration as follows:

1s², 2s², 2p⁶, 3s², 3p⁴

or we can write with the noble gas symbol

[Ne] 3s² 3p⁴

From this configuration, it has been seen that the last electron (16th electron) occupies a 3p orbital (3p⁴) orbital with a downward symbol

The quantum number:

n = 3

l = 1

ml = -1

ms = -1/2

vazorg [7]

Answer:

C. Gene

Explanation:

   The gene is a segment of a DNA (deoxyribonucleic acid) molecule responsible for genetically inherited traits. Each gene consists of a specific DNA sequence that contains a code (instructions) to produce a protein that performs a specific function in the body.

    Most genes are contained in chromosomes. The chromosome consists of a long strand of DNA wrapped around a special protein called histone. Most chromosomes contain several different genes. Human cells contain 23 pairs of chromosomes - one pair of sexual chromosomes (XX in women or XY in men) plus 22 pairs of nonsexual chromosomes called autosomes. Chromosomes are transmitted from parents to children through sperm and eggs. One chromosome from each pair is inherited from the mother and the other from the father.

A factory discharges clean, warm water into a nearby stream. Fish keep dying in this part of stream. Explain why.
Ostrovityanka [42]

Answer:

the fish can't survive in that warm water

Explanation:

when the factory puts that warm water into the stream where the fish live they changed their environment. by adding unknown chemicals and changing the temp of the water the fish start to die.

The fish aren't used to living in that warm water, and if they can't adapt fast enough they will die, also the unknown chemicals that could be in the water will act as a poison for them making that stream unable to support any life.
