A dung beetle is an animal. It walks and runs. Dung beetles eat animal waste, which is called dung. They roll the dung into balls to store for later. An oak tree is a plant. It can have thick branches. Acorns grow on oak trees. Acorns are small nuts with a seed inside. A pine tree is a plant. It has green leaves. Pine tree seeds grow in cones. Trees that grow cones are called conifers. A pear tree is a plant. It has green leaves. Wild pear trees grow in Europe, north Africa, and Asia.

Select the chemical formula for this molecule.

[ "H2Cl2", "HCl2", "H2Cl", "HCl" ]

D

H is the symbol for hydrogen. According to the legend, hydrogen atoms are shown in light gray. Cl is the symbol for chlorine. According to the legend, chlorine atoms are shown in green. This ball-and-stick model shows a molecule with one hydrogen atom and one chlorine atom. The chemical formula will contain the symbols H and Cl. There is one hydrogen atom, so H will not have a subscript. There is one chlorine atom, so Cl will not have a subscript. The correct formula is HCl. The diagram below shows how each part of the chemical formula matches with each part of the model above.
