Answer: Different parts of the sun rotate at different rates.

Explanation: Unlike Earth and other solid objects, the entire Sun doesn't rotate at the same rate. Because the Sun is not solid, but is instead a giant ball of gas and plasma, different parts of the Sun spin at different rates.

Draw the structure of the starting material in the ozonolysis reaction below. Hint: The starting material and product have the s

Crank

<h3>Answer:</h3>

The starting material involved in the formation of 5-Oxoheptanal is 1-ethylcyclopent-1-ene as shown in reaction below.

<h3>Explanation:</h3>

Ozone is one of the reactive allotrope of oxygen. It reacts vigorously with unsaturated compounds like alkenes and alkynes. In this reaction alkene and O₃ first react to produce Molozonide which is highly unstable and rearranges to form a stable ozonide as shown in scheme attached below.

Furthermore, the ozonide on reduction is convertwed into ketones and aldehydes respectively.
