Answer:

there are two types of nomenclature used in organic system. the most widely used and universally accepted system of nomenclature is the IUPAC system of nomenclature. some compounds are referred to by their common name that existed before the IUPAC system or is more widely known than the IUPAC names.

Explanation:

IUPAC ( international union of pure and applied chemistry) system of nomenclature is used to name compounds in organic system. there are some principles to be followed while using this nomenclature. some of them are:-

1) identification of parent chain is the first step. the longest hydrocarbon chain is the parent chain.

2) identification of all the substituent groups of the parent chain is also required.

3) hydrocarbon cyclic ring has a fixed prefix and that is cyclo.

What is the molar mass of Al2(SO4)3

umka21 [38]

Answer:

The molar mass of $Al_2(SO_4)_3$ is 342.145 g/mol

Explanation:

The molar mass is stated as the “mass per unit amount of substance”of a given chemical compound

$Al_2(SO_4)_3$ is Aluminium sulphate. They easily dissolve in water. It is primarily used as a 'coagulating agent' in the drinking water purification and also in waste and sewage water treatment plants,

We know,

Atomic weight of Aluminium = 26.981

Atomic weight of Sulphur= 32.065

Atomic weight of Oxygen = 15.9994

Now molar mass of $Al_2(SO_4)_3$ (Aluminium sulphate) is

=>2(26.981)+3(32.065+4(15.999))

=>53.962 +3(32.065+63.996)

=>53.962+3(96.061)

=>53.962+288.183

=>342.145

Find if the example is correct or not and explain using CER please. Will give 5/5

ELEN [110]

The Lewis structure the student drew is incorrect. The total number of electrons in bonds and lone pairs is equal to the total number of valence electrons available, then a valid Lewis structure is produced.

The correct structure is the following:

The structure that was drawn by the student was incorrect because the total number of electrons around Oxygen were incorrect, there were 6 instead of 8, which was against the octet rule. The correct structure should have 8 electrons around each atom.

If you drop a 50 gram piece of metal with a temperature of 125° Celsius into 1000 grams of water at 20° Celsius, what best descr

Nostrana [21]

Dropping a 50 gram piece of metal with a temperature of 125° Celsius into 1000 grams of water at 20° Celsius would lead to a heat loss by the metal and an heat gain by the water. These loss and gain should be equal since energy cannot be created nor destroyed.
