Which is true about what models allow us to do to the system being studied? Question 8 options: Increase the amount of waste produced. Decrease what we learn about a system. Decrease the amount a system is studied. Increase the size of a very small system, allowing easier understanding of what is occurring.

Increase the size of a very small system, allowing easier understanding of what is occurring.

Explanation:

Models allow us to increase the size of a very small system, allowing easier understanding of what is occurring .

This can be explained with the help of an atom model. An atom model helps students understand what is happening inside the atom by making the atom large enough to be seen with the naked eye. Once the thing can be seen with the eyes it is easier for the brain to interpret chemical reactions or chemical charges inside the atoms.

h let me think

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
