In a power plant, coal enters which of these first?
the boiler
the power lines
the turbine
the smoke stack

Answer;

The boiler

Explanation;

-Coal driven plants generate electricity by burning coal in a boiler to produce steam. The steam produced from the boiler is subjected under tremendous pressure. It then flows into a turbine, that spins a generator to create electricity.

-The steam is then cooled, condensed back into water and returned to the boiler to start the process over.

1 is the answer to this problem

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.
