Answer: I think it could be Decomposition
Explanation: I think is composition because decomposition starts by being together and ends up as two
Communities is all the populations living in an ecosystem at the same time. A predator-prey relationship is an organism that eats another organism.
Answer:
0.5 M
Explanation:
From the question given above, the following data were obtained:
Mass of NaOH = 80 g
Volume of solution = 4 L
Molarity =?
Next, we shall determine the number of mole in 80 g of NaOH. This can be obtained as follow:
Mass of NaOH = 80 g
Molar mass of NaOH = 23 + 16 + 1
= 40 g/mol
Mole of NaOH =?
Mole = mass / molar mass
Mole of NaOH = 80 / 40
Mole of NaOH = 2 moles
Finally, we shall determine the molarity of the solution. This can be obtained as follow:
Mole of NaOH = 2 moles
Volume of solution = 4 L
Molarity =?
Molarity = mole / Volume
Molarity = 2/4
Molarity = 0.5 M
Therefore, the molarity of the solution is 0.5 M.
<u>Answer:</u> The partial pressure of oxygen gas is 57.8 kPa
<u>Explanation:</u>
Dalton's law of partial pressure states that the total pressure of the system is equal to the sum of partial pressure of each component present in it.
To calculate the partial pressure of oxygen gas, we use the law given by Dalton, which is:
We are given:
Total pressure of the tank, = 201.4 kPa
Vapor pressure of helium, = 125.4 kPa
Vapor pressure of carbon dioxide, = 18.2 kPa
Putting values in above equation, we get:
Hence, the partial pressure of oxygen gas is 57.8 kPa
