The chemical formula for strontium sulfide is SrS A chemist measured the amount of strontium sulfide produced during an experiment. She finds that 758 g of strontium sulfide is produced. Calculate the number of moles of strontium sulfide produced.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.
