What is the shape pf a molecule with a triple bond

Explanation:

A molecule with a triple bond will have a linear geometry as the angles between the bonds will be 180 degrees. Hence, it will be a linear geometry.

For example, a molecule of dinitrogen () has nitrogen atoms bonded through triple bond as follows.

                                      :N ≡ N:

Since valency of nitrogen is 5 therefore, each nitrogen will have one lone pair of electrons.

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
