2H + (aq) + Mg(s) → Mg 2+ (aq) + H 2 (g)
Answer:
58.32
Explanation:
The mass number is one mole and for Mg it is 24.306 for O it is 15.999 and for H it is 1.008. because O and H have 2, you multiply them by 2 and add all the numbers and it equals 58.32
Answer:
Natural phenomena such as melting glaciers is due to the rise in temperature. This will result to extinction of flora and fauna. Moreover it can cause extreme flooding due to rise in water level in other water bodies such as rivers, lakes
I would say C is the most correct.
In D it depends on what water source you're using. Let's say it is a waterfall, then the source of the water (melting ice or a lake) may disappear in the future.
If you're using underwater "windmills" placed in the ocean, then you would expect it to last a while as the ocean will not disappear in the near future.
