Answer: 4
2x2 is 4 and that is the same thing as 2+2.
Answer:
Water
Explanation:
Acetone has a higher vapour pressure than water because acetone molecules only experience dispersion forces and diploe interactions as the dominant intermolecular forces.
In addition to these mentioned, water molecules are held together by strong hydrogen bonds. Therefore, water has a much lower vapour pressure than acetone and requires greater energy to break these hydrogen bonds and convert the liquid water to gaseous state.
Answer:
1.422
N/m²
Explanation:
pressure (P) = ρ g h
where ρ= density of continental crust
g= acceleration due to gravity
h is the depth given
density of continental crust is equal to 2.9 g/cm³
= 
g=9.81 m/s²
height = 50,000 m
now,
pressure (P) = ρ g h
pressure (P) =
=1.422 N/m²
Answer:
1. If developed due to the practice of farming, cultivation of the soil for the growing of crops. Similarly, individuals have learned how to use animal to provide food, wool, and other necessities.
2. Obviously, the practice of agriculture is essential in sustaining human life. However, these practices often leave negative impact on the environment. The most prominent of these effects includes climate change, deforestation, pollution, and other unfortunate events.
3. This is due to the fact that different areas harvest different crops, evidently leading to various different foods.
4. Agriculture differs in those regions for developing ones evidently don't have as much experience as those that are already established. It will take a deal of time for them to develop similar foods as the other already developed regions.
