2. Based on your answer to question 1, what do you think could be done to reduce levels of
levacccp [35]

Answer: Carbon dioxide (CO2) is a colorless gas that is naturally present in the air as a result of the natural carbon cycle of our planet. While emissions come from many natural sources, it is the CO2 produced by manmade processes such as fossil fuel combustion and power plant emissions that are problematic. This, in combination with the destruction of natural carbon dioxide sinks through deforestation, is creating an unhealthy environment on our planet and contributing significantly to climate change. here are other things still that can be done to help improve our carbon dioxide situation, even if they aren't tasks the average person can control. For example, as a society, we must continue to push for improved technology in our power plants, so our energy consumption does not produce as much waste.  Improving technology will also help more directly with how much electricity we use. Appliances and electronics are more efficient now than they have ever been in the past, but we should always strive for better regardless. Doing your individual part may not seem like much in the grand scheme of things, but if everyone does their best, it will eventually add up to a significant improvement in the fight against climate change.

Name two rocks that would react to hydrochloric acid and why?
Vadim26 [7]

Answer:

Azurite and Magnesite react with hydrochloric acid.

Explanation:

These 2 rocks contain the carbonate mineral calcite dolomite. Carbonate minerals are unstable in contact with hydrochloric acid. When acid begins to effervesce (fizz) on a specimen, a reaction takes place and bubbles of carbon dioxide evolve, thus indicating the presence of minerals like calcite dolomite.

Hope my answer is correct and helpful :)
