The answer is D. (2,2,2,1)
Explanation:
Below is an attachment containing the solution.
The molarity of dilute solution is calculated using M1V1= M2V2 formula
M1 = molarity 1 ( 6.0 m)
V1 = volume 1 ( 445ml)
V2= volume 2 (2.5 x1000 = 2500ml)
M2= molarity 2 = ?
M2 is therefore = M1V1/V2
= 445 ml x 6.0 M/ 2500ml = 1.07 M
Answer:
The molar solubility of carbon dioxide gas is .
Explanation:
Henry's law states that the amount of gas dissolved or molar solubility of gas is directly proportional to the partial pressure of the liquid.
To calculate the molar solubility, we use the equation given by Henry's law, which is:
where,
= Henry's constant =
= partial pressure of carbonated drink
where = p = Total pressure = 0.400 atm
= mole fraction of
Putting values in above equation, we get:
Hence, the molar solubility of carbon dioxide gas is .
Answer: ENERGY: A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another; the levels in the food chain are producers, primary consumers, higher-level consumers, and finally decomposers. These levels are used to describe ecosystem structure and dynamics.
MATTER: When one organism eats another, the matter, or carbon, nitrogen, and other essential elements, are transferred from one to the other. These elements move from the producers, to the consumers, and eventually to the decomposers, cycling the matter through the ecosystem.
