(2) CH3OCH3 (4) CH3CH2CH3
The Correct answer is CH3COOH
The explanation:
when the electrolyte is: A substance that dissociates into ions in solution and acquires the capacity to conduct electricity.
- Electrolyte is actually a compound that dissolves easily in water and creates a solution that becomes a good conductor of electricity.
- The existence of free ions is the reason why the solution becomes a good conductor of electricity.
-The compounds that release small number of free ions on dissolving in water are called weak electrolytes
-and those that release large number of ions are strong electrolyte.
acetic acid partially dissociates in water to form two ions, H+ and CH3COO- , therefore making it a weak electrolyte
What is the question here?
Answer:
1) The sediment is gradually buried and compacted.
2) The sediment is deposited by wind, flowing water, or other natural processes.
3) Dissolved minerals completely cement the sediment together.
Explanation:
sample containing a mixture of only these
gases at exactly one atmosphere pressure, the
partial pressures of carbon dioxide and ni-
trogen are given as Pco, = 0.285 torr and
PN = 634.034 torr. What is the partial pres-
sure of oxygen?
Answer in units of torr.
Answer:
125.681 torr
Explanation:
The formula to calculate the partial pressure of oxygen:
P(O2) = Pcommon - PCO2 - PN2
1 atm = 760 torr
Therefore you need to find the partial pressure of oxygen:
P(O2) = 760 torr -0.285 torr - 634.034 torr =130.013 torr

Answer:
if volume is increased, the number of collisions per second decreases.
Explanation:
volume is inversely proportional to pressure. Increase in volume leads to decrease in pressure and decrease in volume leads to increase in pressure.
if the pressure is high, it leads to increase in the number of collisions. If the pressure is low, it leads to decrease int he number of collisions.
therefore since volume is inversely proportional, when volume is increased, the pressure decreases and thus the number of collisions decreases.
