The rate of a certain chemical reaction is directly proportional to the square of the concentration of chemical A present and inversely proportional to the concentration of chemical B present. If the concentration of chemical B is increased by 100 percent, which of the following is closest to the percent change in the concentration of chemical A required to keep the reaction rate unchanged?

Answers

Answer 1

Answer:

40% increase

Explanation:

The rate of the chemical, R ∝ [tex] A^2 / B [/tex]

The rate of the chemical,  R= [tex] k * A^2 / B [/tex] where k is a constant

Hence [tex] R*B/A^2 = constant [/tex]

Hence [tex] R1*B1/A1^2 = R2*B2/A2^2 [/tex]

Concentration of B is increased by 100% i.e concentration is doubled

Hence B2=2*B1

R is constant i.e R1=R2

[tex] R1*B1/A1^2 = R1*2B1/A2^2 [/tex]

Solving, we have that

[tex] A2^2= 2*A1^2 [/tex]

Hence [tex] A2=\sqrt{2} * A1 [/tex]

A2= 1.41*A1

This represents approximately a 40% increase in the value of A1

Answer:

Option:(A)- A knowledge about food-borne illness, is the best option to choose from the following options given.

Explanation:

CDC:(Center for Disease control and prevention)

As the CDC approach to preventing the sickness is done in structured way, as the sequence of steps conducting by the institution starts from Conducting a research for the knowledge about the food-borne illness. That how they are formed or originated, as they study the way it spreads from one person to another.

As the researchers do study on the different aspects of the illness or sickness considerations.From its origination to its steps of spreading to different individuals around the infected person.

The best way that the CDC recommends is prevent sickness is B) knowledge of food safety.

What is food safety?This refers to knowing how to treat food such that it does not lead to you getting sick. Includes guidelines provided by the CDC on things such as food preparation and sanitation.

Practicing these things will go a long way in ensuring that your chances of incurring sickness from food are vastly reduced.

In conclusion, option B is correct.

A single-line ACL has been added to a router configuration using the command "ip access-list 1 permit 172.16.4.0 0.0.1.255".
The configuration also includes the "ip access-class 1 in" command in VTY configuration mode.
Which answer accurately describes how the router uses ACL 1?

a. Hosts in subnet 172.16.4.0/23 alone can telnet into the router.
b. CLI users cannot telnet from the router to hosts in subnet 172.16.4.0/23 alone.
c. Hosts in subnet 172.16.4.0/23 alone can log in but cannot reach enable mode of the router.
d. The router will only forward packets with source addresses in subnet 172.16.4.0/23.

Answers

Answer:

The correct option is A: Hosts in subnet 172.16.4.0/23 alone can telnet into the router.

Explanation:

Hosts in subnet 172.16.4.0/23 alone can telnet into the router. The router takes care as long as the ACL 1 in the access-class is being used for the parameter IN or OUT, because it totally changes its operation.
