Mrs. Crater's first reaction to Shiftlet is to try to discern whether he is a tramp or not. She watches him with suspicion and wariness before eventually offering him a ride to their farm.
The combustion reaction begins with the rapid combination of a fuel and oxygen. This produces heat and light (fire).
At 40 mph, a driver's reaction time is typically around 1.5 seconds. During this time, a vehicle travels approximately 88 feet, which is the distance covered while the driver perceives a need to stop and begins to react. Therefore, the total stopping distance will include this reaction distance plus the braking distance, which can vary based on road conditions and vehicle type. Overall, the total distance to stop from 40 mph can be around 120-150 feet, depending on these factors.
The reactants
The transition reaction begins with the molecules pyruvate, coenzyme A (CoA), and NAD+. Pyruvate is converted to acetyl CoA, producing NADH in the process.
In the graph of an enzymatic reaction, the line begins as a straight line because the reaction is initially occurring at a constant rate, where substrate availability is high and the enzyme is not saturated. This reflects a linear relationship between substrate concentration and reaction rate, as more substrate leads to more frequent enzyme-substrate collisions. As the reaction progresses and substrate is consumed, the rate starts to plateau, indicating that the enzyme is approaching its maximum activity and becoming saturated.
Mrs. Crater's first reaction to Shiftlet when she sees him from a distance is to be "unsure, stiffening, and retreating slightly."
The substances that are present when a chemical reaction begins are reactants, at the end of the reaction they form products.

A chemical reaction begins with reactants and ends with products.
The rate of the reaction begins to decrease as reactants are used up (apex)

If a driver is tired, their reaction time will be slower, causing the thinking distance to increase. This means it will take longer for the driver to process information and decide to apply the brakes. As a result, the vehicle will travel a greater distance before the driver even begins to brake.
No: the substances present at the beginning of reaction are the reactants or reagents.
