Answer: There are three main places where volcanoes originate: Hot spots, Divergent plate boundaries (such as rifts and mid-ocean ridges), and. Convergent plate boundaries (subduction zones)
Explanation:
Volcanoes often form in the areas where tectonic plates make contact. The friction created between two plates by the constant movement melts the Earth's crust, causing the rock underneath the crust to turn into magma due to the great temperatures created by friction. ... Volcanoes may be formed at subduction zones
Explanation:
1. Only alcohols forms hydrogen bond between themselves and with other compounds containing an O-H, N-H, or F-H bond, such as water.
2. Alcohols up to 4 carbons are miscible in water because they have hydrogen bonded to oxygen and can form hydrogen bond with water. However, it is not possible for ethers.
3. When comparing ethers and alcohols of similar molecular weights, ethers have lower boiling point than alcohol. This is because of the presence of hydrogen bond in alcohols.
Answer:
cfcl3
Explanation:
When the cfcl3 in the atmosphere is hit by UV rays from the sun, it decomposes to Cl atoms. These Cl atoms then react with the ozone producing O2 and ClO. The ClO bombard with O atoms splitting the ClO up and the free Cl atom again bonds to another O3 molecule hence reducing it. One ClO can reduce several O3 molecules (up to 100,000) creating an ozone hole.
2Cl + O3 → 2ClO + 2O2
2ClO + 2O → 2Cl + 2O2
Since the atomic mass consists of protons and neutrons, that would be the answer.

Answer:
The law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another. This means that a system always has the same amount of energy unless it's added from the outside.
