• How is it affecting coral reefs?
• How can we prevent it?

Answers:

Part 1: Crystal

1. -We heated the sulfuric acid and we dissolve the copper oxide and then the solution turned blue.

- We filtered the blue solution 

- We put it in an evaporating basin

- We put the water in the beaker and let it boil

-  We watch the solution crystallize

2. 

3. Copper Sulfate

Part 2: Acid Rain 

1. When fossil fuels such as coal, oil and natural gas are burned, carbon dioxide, nitrogen oxides and sulfuric dioxide escape into the air. These molecules dissolve in the water in the clouds and make the rainwater in the clouds and make the rainwater more acidic than normal. When this happens, it is called acid rain.

2.  Coral Reefs in Acidic Waters. Increasing amounts of carbon dioxide are released into the atmosphere from burning of fossil fuels. ... As seawater gets more acidic with more carbon dioxide dissolved in it, these creatures might have a harder time making their skeletons and shells.

3. Because nitrogen oxides are created in the process of burning coal and other fossil fuels, some power plants are changing the way they burn coal. A great way to reduce acid rain is to produce energy without using fossil fuels. Instead, people can use renewable energy sources, such as solar and wind power. Link Link
