Answer:
Plants take carbon dioxide out of the atmosphere, but they also have other effects, such as changing the amount of evaporation from the land surface. ... The plants absorb carbon dioxide for photosynthesis through the same pores (called stomata). But when carbon dioxide levels are high, the leaf pores shrink.
Explanation:
Answer:
M₁ = 0.178 M
Explanation:
In case of titration , the following formula can be used -
M₁V₁ = M₂V₂
where ,
M₁ = concentration of acid ,
V₁ = volume of acid,
M₂ = concentration of base ,
V₂ = volume of base,
from , the question ,
M₁ = ?
V₁ = 20.0 mL
M₂ = 0.158 M
V₂ = 22.60 mL
Using the above formula , the molarity of the acid , can be calculated as ,
M₁V₁ = M₂V₂
M₁ * 20.0 mL = 0.158 M * 22.60 mL
M₁ = 0.178 M
Answer:
Answers are in parentheses.
In the Bohr model of the atom, the electrons move in fixed, (circular) paths around a dense positively-charged nucleus. On the other hand, the quantum mechanical model shows the probability of finding an electron as a (cloud) of negative charge.
Answer:
As a gas is compressed in a cylinder its pressure
As the compression proceeds the volume of the chamber is decreasing and since mass is same, density increases. Similarly as volume decreases the number of gas molecules colliding with the walls increases as the density increases, so the pressure on the wall also increases.
