Answer:
Montreal protocol is an international treaty signed by many countries across the globe to regulate the manufacturing and usage of substances like chlorofluorocarbons and to take measures to protect the ozone layer.
Explanation:
Montreal protocol was signed on 16th September 1987 and it was enforced on January 1st 1989. It was singed all the 197 countries who acknowledged the importance of restoring and protecting the ozone layer. The treaty has various articles under it like -(Article 2) Calculation of control levels to control the usage of ozone depleting substances.
some of the recent measures to reduce CFCs are:-
1. UN environment programme had released a list of products for the public that deplete the ozone layer and another list that doesn't. so that the public can make wise purchasing decisions.
2. Safe disposal of appliances like ACs, refrigerator and coolers that contain CFCs
3. Different policies are made by the UN environmental protection agency and organisations like national resource defense council to regulate and reduce the production and usage of CFCs.
Answer:
10.875 miles
So 87 minutes
.125 miles per minute
So just multiply int his case
87*.125
You’d get 10.875
The skeletal structure of an organic compound is an abbreviated representation of its molecular structure, they are quick and easy to draw.
For example, the following image shows the skeletal structure of a compound:
The peaks represent the carbons. We must remember that carbon can have a maximum of 4 bonds.
Now, I will show you how is the structure of this specific compound:
This is ternary alcohol, called 2-methyl-2-butanol. If you see carefully, you will notice that each carbon has 4 bonds. The functional groups present will be OH. The skeletal structure will be:
The relationship between volume and pressure is described in the Gay-Lussac's law. That is,
P₁V₁ = P₂V₂
Substituting the known values,
(75 mL)(145 atm) = (500 mL)(P₂)
The value of P₂ is equal to 21.75 atm.
According to Bronsted-Lowry theory of acids and bases, an acid is proton donor and a base is proton acceptor. When an acid loses the proton, it forms the conjugate base of the acid. Similarly when a base accepts a proton, it forms the conjugate acid if that base. A conjugate acid base pair differs by a single proton.
Given the weak acid . It can lose a proton to form the conjugate base.
Therefore, the conjugate base of is .
