Answer:
The sum of each elementary step in a reaction mechanism must yield the overall reaction equation. From the rate law of the rate-determining step it must agree with the experimentally determined rate law. The rate-determining step is the slowest step in a reaction mechanism. Because it is the slowest, it determines the rate of the overall reaction.
Explanation:
Answer:
Object B has a density of 2.5 g/cm³ which is greater than object A by 1 g/cm³
Explanation:
Since we know that the formula for density is d=m/v, we can divide each mass by its corresponding volume to find the densities
12/8=1.5
20/8=2.5
So we know that object B has a greater density than object A by 1 g/cm³ (gram per cubic centimeter). Also the standard unit for density is kilograms per cubic meter but I used gram per cubic centimeter since they were the given units. 1cm=100m, 1000g=1km
Urine color is the most effective method for measuring hydration status before and after exercise
Urine color is yellow color from a pigment called urochrome or urobilin. Darker pee contains less fluid, whereas lighter urine is more diluted. Dehydration may be indicated by very black urine. Don't worry if your urine doesn't match the color scheme.
Normal urine color is a pale yellow, however light amber is also acceptable. If your pee appears dark amber, you may be dehydrated and should drink additional water to compensate. Urine naturally contains yellow pigments known as urobilin or urochrome. The darker the pee, the more concentrated it is. Dehydration is the most common cause of dark urine color

Answer:
4 tert-butylcyclohexane will have the higher Rf value when ethyl acetate is used as the developing solvent because the 4-tert-butylcyclohexanol is the more polar compound that can form hydrogen bonds with the polar silica gel stationary phase.
this means less polar 4-tert-butylcyclohexanol will have a higher Rf
