A racing car drives at constant speed around the horizontal track. At points, $A, B$ , and $C$ draw a vector showing the magnitude and direction of the net force on this car. Make sure that the lengths of your arrows represent the relative magnitudes of the three forces.

chemistry

Unless under pressure, carbonic acid $\left(\mathrm{H}_{2} \mathrm{CO}_{3}\right)$ in aqueous solution breaks down into carbon dioxide and water and carbon dioxide is evolved as bubbles of gas. Write an equation for the conversion of carbonic acid to carbon dioxide and water.
