1. Yes because the ocean takes in the carbon dioxide from the air. This causes more acid in the water, this makes it hard to make shells and skeletons for the seal life that need them.
2.No because it isn't harmful unless it builds up. But there is people who work to clean and limit the chances of build-up.
Hope this helps :)
Based on the balanced chemical reaction presented above, every mole of magnesium (Mg) yields one mole of diatomic hydrogen (H2). When converted to masses, every 24.3 grams of magnesium yields 2 grams of hydrogen.
From the given, there are 20 grams of magnesium available for the reaction. With this amount, the expected yield of hydrogen is 1.646 grams. To calculate the percent yield, divide the actual yield to the hypothetical yield.
*The case is impossible because the actual yield is greater than the theoretical yield.
If we assume that there had been a typographical error and that the actual yield is 0.7 grams instead of 1.7 grams, the percent yield becomes 42.5%. Thus, the answer is letter E.
Carbon can form four bonds with other molecules/elements. It is the most important element in Organic Chemistry.
