Reaction distance is the measurement of how far a vehicle travels between the time a driver realizes the brakes must be applied and when the driver actually starts pushing on the brakes. If the driver is capable and paying attention, the reaction distance lasts about three-quarters of a second.

When a reaction is described through a balanced equation, it is possible to determine the exact amount of each atom, ion and molecule needed on each side of the equation. Balanced equations are determined using a technique known as stoichiometry.

Acid rain is formed when nitrogen oxides or sulfur oxides in the atmosphere react with suspended water droplets and produce acids. The chemical reaction equation for the production of acid rain resulting from sulfur oxides is: SO2 + HOH - H2SO3. The reaction equation for acid rain produced from nit

Reaction time is measured by determining the amount of time between when an event occurs and when the body reacts to it. This is done using a stopwatch, electronically with a computer or using measured distance. Reaction times vary based on age, health, mental state and other factors.

The distance formula indicates that distance is equal to the square root of {x(sub 2) - x(sub 1)} (squared) + {y (sub 2) - y (sub 1)} (squared). The "x" and "y" values reflect the respective horizontal and vertical coordinates of each point on a graph; the formula is used to compute the distance bet
