What is the relationship
Zielflug [23.3K]

Answer:

The stomach, gallbladder, and pancreas work together as a team to perform the majority of the digestion of food. Food entering the stomach from the esophagus has been minimally processed — it has been physically digested by chewing and moistened by saliva, but is chemically almost identical to unchewed food

A measure of peak separation in a chromatographic method that equals the difference in retention time for two components divided
Mademuasel [1]

A measure of peak separation in a chromatographic method that equals the difference in retention time for two components divided by the average of their peak widths is the definition of resolution.

Retention time can be referred to as the amount of time a solute spends in the stationary and mobile phases of a column.

The analyte's interaction with the stationary phase determines the longer retention period.

The duration of retention will increase as the interaction becomes more strong.

Resolution is defined as the peak separation in a chromatographic procedure that is equal to the difference in retention time for two components divided by the average of their peak widths.

What is the rate of a reaction if the values are
3241004551 [841]

Answer:

Explanation:

Hi there,

To get started, let's first observe our rate law:

R=k[A]^2[B]^2     we typically use square brackets [x] for chemistry kinetics, because they specifically tell us we are dealing with <em>concentrations</em>.

This rate law is in fourth-order, because the concentrations powers add up to 4. We are not told the unit of time for this prompt (unless you know it), so I just assumed the time unit to be "time."

To calculate the reaction rate, we simply plug in the concentration of A and B into the rate law. k is the <em>rate constant</em> and stays the same for an individual reaction.

R=(0.1 \ M^{-3}*time^{-1})[1 \ M]^2[2 \ M]^2=0.4 \ M/time

Thus, the rate of reaction with those concentrations is 0.4 M/time.

Notice, the rate constant does in fact have units of it own. The unit for k can be calculated by knowing that:

  1. Rate (R) must end up with units of concentration (M) per time.
  2. The concentrations raised to a power can be used to help solve for the units of k.

Which of these processes indicates that smelting copper is a chemical change
BlackZzzverrR [31]

The correct answer is D:


it involves breaking molecular bonds between copper compounds .


The explanation :


-when we melt a copper it is a physical change because the substance is still copper and have the same shape.


- but for example Burning a copper it is a chemical change. Fire activates a chemical reaction between copper and oxygen.


-The oxygen in the air reacts with the copper and the chemical bonds are broken.


- the chemical change is changing the other compound bonded to the copper atoms.


So, the correct answer is D
