Answer:
Once ignited, a ribbon of magnesium metal burns freely in air to form solid magnesium oxide in the form of a white powder. The reaction is plainly spontaneous even though ΔS is negative.

Explanation:
Renewable energy sources refers to those energy sources that can never be depleted. This means that they can be used severally without getting exhausted. Solar, biomass, wind and hydroelectric power are all renewable energy sources.
Hence, from the perspective described above, we can say that wind is a form of solar energy because wind is formed when the air is heated by the sun.
Hydroelectric power is driven by the water cycle. This water cycle somehow depends on the sun to run efficiently. So, hydroelectric power can also be considered to be a form of solar energy.
Id say true, as if it exceeds the flow capasity there would be to much water flowing,therefor causing a flood
Answer:
A.) Brønsted-Lowry bases
Explanation:
Amines have a lone pair of electrons.
Brønsted-Lowry bases donate a lone pair of electrons in exchange for a hydrogen ion.
Therefore, if exposed to an acid, amines will give up electrons in order to bond with a hydrogen. This makes them Brønsted-Lowry bases.
