Front

What type of process is vaporization?

Back

Endothermic process, as it requires heat absorption.

Front

What effect does vasodilation have on blood pressure?

Back

Vasodilation causes blood pressure to decrease.

Front

What is the name of the compound CH3COCH2CHO?

Back

2-methylbutanal.

Front

What laboratory equipment is best for measuring 800μL of a solution?

Back

Micropipette.

Front

Why is CH3COCH2F more acidic than CH3COCH3?

Back

Due to the presence of an electron withdrawing group.

Front

Define vaporization.

Back

The process of converting a liquid into vapor.

Front

What is the difference between endothermic and exothermic processes?

Back

Endothermic processes absorb heat, while exothermic processes release heat.

Front

Explain the concept of vasodilation.

Back

Vasodilation is the widening of blood vessels, which decreases blood pressure.

Front

What is a micropipette used for?

Back

A micropipette is used to measure and transfer small volumes of liquid accurately.

Front

What role do electron withdrawing groups play in acidity?

Back

They increase acidity by stabilizing the negative charge on the conjugate base.
