Answer: I would usually try my BEST to get help from yt videos. I recommend using yt that give the most kindergarten type speaking technique, this is really weird to say but it helps just incase you can be stressed out about the words being given by teachers in Chemistry. And I recommend writing down the notes when they explain as well. Hope this helps!

Answer:

- to produce energy without using fossil fuels instead using renewable sources solar and wind power.

 

- reduce the amount of sulfur dioxide released from coal-burning power plants. One option is to use coal that contains less sulfur.

- install equipment called scrubbers, which remove the sulfur dioxide from gases leaving the smokestack.

- While one car alone does not produce much pollution, all the cars on the road added together create lots of pollution. Therefore, car manufacturers are required to reduce the amount of nitrogen oxides and other pollutants released by new cars. One type of technology used in cars is called a catalytic converter. This piece of equipment has been used for over 20 years to reduce the amount of nitrogen oxides released by cars.

- recycling is one way that is often use less energy than producing a new products from raw materials so the use of energy that obtain mainly from fossil fuel will be reduced and that reduced the emissions of toxic gases.

Here goes the question with no exact answer, lol <3


Scientists tell us that the observable universe is about 90 light years but then I wonder how they calculated that because the universe is immense!

I'm sorry but I can't go deeper into explaining as that's a tough question.

What is the density of carbon dioxide gas if 0.196g occupies a volume of 100mL?
-BARSIC- [3]

We know that the equation for density is:

D=\frac{m}{V}

where D is the density, m is the mass in grams, and V is the volume.

Given two of the variables, we can then solve for density:

D=\frac{0.196g}{100mL}= \frac{0.00196g}{mL}

So therefore, we now know that the density of carbon dioxide gas is 0.00196g/mL.
