Answer:
Covalent bonds are the types of Bond which is formed by sharing of an electron between two atoms of same element or two different elements. The bond which is formed by the completely lost or gained of an atom is known as ionic bond.
Explanation:
The most common example of covalent bond is formed from carbon atom. The valence of carbon atom is 4. Therefore, it is very hard to gain or lose an electron from the carbon atom. Therefore, the carbon tends to share the electron instead of completely losing or gaining the electron.
Ionic bond is very common and it can be formed by many elements from the periodic table. Ionic bond is more stable and stronger when compared to the covalent bond in nature.
<u>Answer</u>:-
The merely correct option is False.
Explanation:
Since it is not possible to equally preserve all organisms due to the following:
• Not all of them got the same structure and components
• The decay process
• Life span
• Sedimentary environment
• Taphonomic conditions
• The speed of burial, time of burial and kinds of organisms buried
• Chemistry of environment and many more.

Answer:
A vaccum should be used for the control group chamber.
Explanation:
In an experiment, a control is an experiment or observation designed to minimize the effects of variables other than the independent variable. The introduction of a control increases the reliability of the results; often through a comparison between the control measurements and the other measurements.
A vaccum according to this experiment is a chamber that will have no pressure within it. This will give a benchmark of the effect of pressure in this experiment.
5 atm pressure must be applied to compress the gas to a volume of only 150.0 ml.
<h3>Given</h3>
Mass of oxygen at room temperature =500.0 ml
Volume of pressure = 50 atm pressure.
The gas to a volume = 150.0 ml
<h3>Explanation</h3>
The volume decreases by the factor = 500.0 mL / 150.0 mL
= 10 / 3
The pressure of the gas increased by a factor of 10/3 , which would make its final value equal to
= 5.00 atm
So, 5 atm pressure must be applied to compress the gas to a volume of only 150.0 ml.
