Organic compounds are chemical compounds which typically consists of one or even more atoms of carbon, hydrogen, oxygen and also occasionally nitrogen or sulphur. Carbon and also hydrogen are the primary element that is had in most organic compounds.

You are watching: Which one of the following groups of chemical compounds is composed entirely of organic compounds?

Option A is wrong because calcium phosphate is not an organic compound, although all the other compounds in the option are organic compounds.

Option B is wrong because calcium chloride is not an organic compound

Option C is wrong additionally as calcium sulphate is not an organic compound

Option D is correct as all are organic compounds

Of an 8 M solution of HCI, 1 L is diluted to 2 M. What is the volume of the dilutedsolution?
jok3333 <9.3K> The volume of diluted solution is 4 L


According to the dilution regulation,


wright here,

= molarity of stock
solution = 8 M

= volume of stock
solution = 1 L

= molarity of diluted
solution = 2 M

= volume of diluted
solution = ?

Putting in the worths we get:



Therefore, volume of diluted solution is 4 L

Write a chemical equation representing the initially ionization power for lithium. use e− as the symbol for an electron.
simply <345>

The chemical equation representing the first ionization power for lithium is given by;

Li → Li + e-

Additional Explanation;

Ionization energy

Ionization power is the energy forced to rerelocate outerthe majority of electrons from the outerthe majority of power level. Energy is forced to remove an electron from an atom.The closer an electron is to the nucleus the more energy is forced, because the electron is even more tightly bound to the atom hence making it more difficult to rerelocate, thus better ionization power.Ionization energy increases across the durations and decreases dvery own the group from height to bottom. In addition, the ionization energy increases with subsequent removal of a 2nd or a 3rd electron.

First ionization energy

This is the power required to rerelocate the first electron from the outera lot of power level of an atom.Energy needed to rerelocate the second electron to form a divalent cation is called the second ionization power.

Trends in ionization energy

1. Down the group(top to bottom)

Ionization energy decreases dvery own the groups in the regular table from height to bottom.It is because as you move down the group the number of energy levels rises making the outera lot of electrons gain additionally from the nucleus reducing the toughness of attractivity to the nucleus.This suggests less power will certainly be required compared to an atoms of facets at the peak of the teams.

2. Across the period (left to right)

Ionization power increases across the period from left to appropriate.This deserve to be defined by a rise in nuclear energy as extra protons are included to the nucleus across the duration raising the stamina of attractivity of electrons to the nucleus.Consequently, more energy is necessary to rerelocate electrons from the nucleus.
