Why was the clean air act of 1990 so important and how specifically did it change what factors were doing?
Charra [1.4K]
The clean air act of 1990 was important because it helped reduce pollution and keep the enviornment safe. The act organized the idea's of 'safe' in regards to the ozone layer and also the air (generally). This meant that the amount of acid rainfall was controlled. It set rules and policies regarding polluting. Basically, people needed to wake up and think about the enviornment. Companies, people, and even communities were all now responsible for keeping what they breathe (air) clean.

Does this explain it pretty well? If not, please feel free to comment! Thanks for being part of Brainly. :)

Methyl red is a common acid-base indicator. it has a ka equal to 6.3 × 10–6. its un-ionized form is red and its anionic form is
Maksim231197 [3]
Hello!

The pKa of an indicator tells us the pH where it changes color. The pKa of Methyl red is 

pKa=-log(Ka)=-log( 6,3*10^{-6} )=5,20

So, at a pH=7,8, Methyl Red would be at a pH over its pKa, so it would be in its basic form. The Basic Form of Methyl Red is Yellow, so the solution would be Yellow.

Have a nice day!
