Answer:
Partial pressure of CO2 = 16 atm
Explanation:
Total number of moles of gases = 4+1 = 5 moles
Mole fraction of CO2 = 4/5
Partial pressure of CO2 = mole fraction of CO2 × total pressure
Partial pressure of CO2 = (4/5) × 20
Partial pressure of CO2 = 16 atm
Answer:
The answer to your questions is: C. Sulfides
Explanation:
A. Phosphates these compounds do not have sulphur, they are composed by phosphate and oxygen, So this answer is wrong.
B. Sulfates are formed by sulphur and oxygen, not for a metal, then this is not the right answer.
C. Sulfides are molecules formed by a metal and sulphur, this is the anwser to the question.
D. Silicates are formed by sillicon and oxygen, this option is incorrect.
Answer:
BRAINLIEST PLEASE!!!
A = Smooth Endoplasmic Reticulum
B = Vacuole
C = Mitochondria (Plural)
D = Nucleolus
E = Cell Wall
Explanation:
This is obviously a plant cell. Animal cells do not have cell walls(E), and most animal cells will not have a vacuole(B). Smooth Endoplasmic Reticulum: This produces protiens (contains ribosomes) but when looked through a microscope, will appear to be smooth. The vacuole(B) is like a storage for the plant cell, and it helps support the plant cell. This is the reason why plants “droop” when you don’t water them for a long time. Mitochondia (Plural) processes nutrients for the cell. The nucleolus(D) covers the nucleus. It’s main function is to process RNA and combine it with proteins. The cell wall(E) helps support and protect the cell.
True some explanations are not always based on empirical evidence
