Answer:
11 yes
12 H2O( water molecules)
13 3H2O( water molecules)
Explanation:
Sry, my phone's a potato, so I didn't read it properly, so I'm not sure about the question 11.
11-yes, they stay together, but they release 3 molecules of OH an H.
12- here it talks about what will happen with OH and H: they will be H2O (water molecules).
13- and here we end it with the informations that we got: 3 fatty acids+ glycerol---> fat+ 3H2O( the 3 H and 3 OH)
It can uplift slowly due to the pressure of Earth’s plates.
It can melt into magma and recrystallize as extrusive igneous rock.
Answer: high pressure because it's stable
Explanation:
Air mass is volume of air which has stable temperature, humidity and pressure horizontally. Over time, each air mass acquires properties of the region by residing over same part of a surface.
Areas of low pressure and high pressure occur where there is warm air and cold air respectively. An air mass usually forms over an area of high pressure. Warm air rises up and cold air takes its place. Warm air has low density and low pressure where as cold air has high density and pressure and therefore, sinks to the bottom. This is a stable condition. The movement of air mass is responsible for maintenance of temperature conditions on Earth.
The correct answer should be 1500 K. I hope I helped.
