How does a lone pair contribute to molecular shape? a. it is too small to affect the molecule's shape. b. it takes up space like an "invisible" atom. c. it forces the molecule into a tetrahedral shape. d. it lets the bonding pairs spread out more.

 B. It takes up the space like an "invisible" atom.

Explanation:  Lone pair of electrons are the pair of non bonding electrons which does not take part in the bonding unless and until there is a need of it.

Lone pair of electrons do occupy some space and thus are not too small to affects the molecule's shape.

These never forces the molecules into a tetrahedral shape.

As shown in the water molecule, they are repelling the bonding pairs of electrons so as that the tetrahedral shape gets distorted and force the molecule to take the angular shape.

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.

i think that the answer is c
