Which is a reason to use rate laws?

Chemistry

Sliva [168]2 years ago

Answer:

to find the new rate when the concentration of reactants changes

Explanation:

The rate of a chemical reaction is the rate of change of concentration of reactants or products with time. As a reaction progresses the concentration of reactant decreases and the concentration of product increases. The rate law is the product of the rate constant and the molar concentration of the reactant(s) involved in the chemical reaction. Due to direct proportionality between rate law and concentration of reactants, the rate law is directly affected by the change in the concentration of the reactants.

\huge{ \underline{ \boxed{ \bf{ \green{Answer:}}}}}

Inside the stomach, Hydrochloric acid kills micro-organisms in the food. Stomach juices begin to break down <u>proteins</u> to amino acids.

✤ So, Fill the blank with proteins.

<h3><u>Explanation:-</u></h3>
  • Inside the stomach, the digestion of proteins starts due to the action of pepsin enzyme.
  • But this enzyme remains inactive and is activated by the Hydrochloric acid(HCl).
  • The Hydrochloric acid also helps in killing the germs and microbes which entered along with food.
  • The mucous lines the wall of stomach to protect it from the harm caused by HCl because HCl is a strong acid.
  • In stomach, The partial digestion of proteins occur and rest is digested in the small intestine by Trypsin(Pancreatic enzyme) and Intestinal juices.

A child picks up a tennis ball tied to the end of a rope. He swings the rope around, over his head, in a circle. Once the ball i
kkurt [141]

Answer:

The ball will fly tangential to the original circle

Explanation:

The image here is missing, however we can still answer to the question.

In fact, the circular motion of the ball when it is tied to the rope is a combination of two separate effects:

1- The centripetal force, in the form of the tension in the rop, that pulls the ball at any time towards the centre of the circular path

2- The inertia of the ball, which tends to continue its motion in a straight direction, tangential to the circle and perpendicular to the direction of the centripetal force

When child let the string go, there is no more tension in the string acting on the ball, and therefore, there is no longer a centripetal force.

As a result, number 1) disappears, and therefore there is only the inertia of the ball that will determine its motion: and therefore, the ball will continue its motion straight in a direction tangential to the original circle.

What does the rf value describe on a microscopic level why is this important?
lys-0071 [83]

Answer: The retention factor describes the rate at which a compound migrates on a microscopic level.

The retention factor (Value) serves as a simple measurement of the relative binding of the compound of interest under the experimental conditions.

Retention factor values are used in identification purposes;

• Use to determine the affinity of the solute to the solvent

• Greater retention factor means greater affinity of solute to the solvent
