1. Which of the following compounds will have the highest melting point? (A) Srs
(B) Bas
(C) Bes
(D) MgS

2.Briefly explain your response to Q1:

Firstly, the water in the dams hold gravitational potential energy as they are above ground level. the gravitational potential energy is then transferred to kinetic energy as it falls, spinning the turbinethe turbine then spins the generator, which is a large magnet surrounded by metal coils. by doing this, the generator generates electricity. in this action, the energy transfer taken place is kinetic to electric energy

Ibelieve the answer is weathering,hope my answer has you : ) 

Melting increases as mass increases. since alkanes are not branched molecular structures, the one with the heavier mass will have higher melting point.  octane's mp > butane's mp

Neptunium is the only of those 4 that doesn’t occur naturally.
