They form an ionic bond by exchanging two electrons.
Explanation:
Magnesium loses two electrons and oxygen gains these electrons so ionic bond is formed
Just divide the two (2 / 0.05) and you will get your answer; there are 40 drops of bloodin the collection tube.
The element that is most reactive to gas is Hydrogen
The distance from one crest to another crest or from one trough to another trough is called wavelength. Hope it helps
Answer : The work done by the system is, 2.2722 J
Explanation :
The expression used for work done in reversible isothermal expansion will be,
where,
w = work done = ?
n = number of moles of gas = 0.00100 mole
R = gas constant = 8.314 J/mole K
T = temperature of gas =
= initial volume of gas = 25 mL
= final volume of gas = 75 mL
Now put all the given values in the above formula, we get:
Therefore, the work done by the system is, 2.2722 J
