Answer:
Explanation:
I can explain if you ask
In an experiment, equal amounts of water and soil were first heated and then left to cool. The graph shows the change in tempera
ture for each with time.
A graph with the title Change in Temperature is shown. The y axis title is Temperature in degree C and the x axis title is Time in seconds. An inverted U shaped curve labeled A is plotted. A flatter curved line labeled B is also shown plotted on the graph.
Which statement about the curves A and B is true?
Curve A represents how soil takes longer to heat and longer to cool.
Curve B represents how water takes longer to heat and longer to cool.
Curve A represents water as it heats rapidly and cools slowly.
Curve B represents soil as it heats slowly and cools rapidly.

Answer : Linear
Explanation : Hydrogen Cyanide (HCN) when drwan in the Lewis diagram shows carbon atom at the center with no lone electron pairs.
The carbon and nitrogen atoms are bonded through a triple bond which counts as "one electron pair".
The molecule has two electron pairs in all and appears to be linear.
Also, according to the VSEPR theory; the electron clouds on atoms around the carbon will try to repel each other.
They will get pushed apart, which gives HCN molecule a linear molecular geometry or shape.
The bond angle that is developed will be 180 degrees since it has a linear molecular geometry of HCN. The hybridisation observed in this molecule is SP.
