<u>Explanation:</u>

Phosphorus and oxygen atoms are considered as non-metals and two non-metals usually form covalent bonds.

A covalent bond is formed when sharing of electrons takes place between the atoms forming a bond.

The nomenclature of a covalent compound is given by:

  1. The less electronegative element is written first.
  2. The more electronegative element is written then, and a suffix is added with it. The suffix added is '-ide'.
  3. If atoms of an element is greater than 1, then prefixes are added which are 'mono' for 1 atom, 'di' for 2 atoms, 'tri' for 3 atoms and so on..

From the two atoms, less electronegative atom is phosphorus and thus, is written first.

Naming of the given compound are as follows:

1. P_4O_7 = The name given to this compound is tetraphosphorus heptoxide

2. P_2O_5 = The name given to this compound is diphosphorus pentoxide

3. P_2O_4 = The name given to this compound is diphosphorus tetroxide

4. PO = The name given to this compound is phosphorus monoxide

Answer:

The mechanical energy produced on burning fossil fuels is transformed into chemical energy stored in carbon dioxide.

Explanation:

When fossil fuels are burnt, mechanical energy is produced. Remember that according to the first law of thermodynamics, energy is neither created nor destroyed but can be transformed from one form to another. Hence the mechanical energy produced when fossil fuels are burnt for industrial use, heating of homes, electricity generation , cooking etc the mechanical energy produced is not 'lost'. It must be transformed in to another form of energy.

In the image the arrow G----> C, shows the mechanical energy produced when fossil fuels are burnt are stored as chemical energy in CO2 bonds. CO2 is found in the atmosphere, hence the arrow point upwards from the source towards the atmosphere (C is the atmospheric reservoir of CO2). The energy is subsequently used by producers to produce chemical energy stored in food.

Draw the condensed structural formula in the equation for the saponification of trimyristin with koh
Ludmilka [50]

Explanation: Saponification reaction is a reaction in which hydrolysis of fats takes place under basic conditions giving glycerol and a salt of corresponding fatty acid.

We are given a Fatty acid called as Trimyristin.

Its reaction with KOH leads to the formation of soap and is given by the equation:

Trimyristin+3 KOH\rightarrow Glycerol+Soap

C_{45}H_{86}O_6+3KOH\rightarrow C_3H_5(OH)_3+3CH_3(CH_2)_{12}CO_2K

The condensed structural formula for the equation is given in the image attached.
