Answer:
Partial pressure of oxygen = 190 mmHg
Explanation:
From the question;
Mixture contains only nitrogen and oxygen
Total pressure of the mixture = 480 mmHg
Partial pressure of nitrogen = 290 mmHg
Dalton's law states that the pressure of a system is as a result of the sum of the partial pressures of the individual components of the mixture. This means that in this mixture;
Pressure of mixture = Partial Pressure of Nitrogen + Partial Pressure of Oxygen
480 = 290 + Partial pressure of oxygen
Partial pressure of oxygen = 480 - 290
Partial pressure of oxygen = 190 mmHg
Answer:
323.99 mg
Explanation:
We need to find the mass of the aspirin tablet that contains 5.0 grains of aspirin.
1 pound = 7000 grains
We know that, 1 pound = 453.592 grams
Also, 1 pound = 453592 mg
Hence, 4 grains of aspirin contains 323.99 mg.
Answer: Radiant energy to chemical energy. Explanation: Photosynthesis is known for the radiant energy transformation into chemical energy. It is a process where plants to take in sunlight, water, & CO2 and convert them into oxygen, and glucose, in this process CO2 is removed from the air. In the process of photosynthesis, the energy that is captured by the sun is stored in the form of carbohydrates. The photosynthesis process occurs in the chloroplast which is present in the plants, and the pigment is known as chlorophyll which helps to make plant green.
