Answer:
Fluorine has seven electrons in 2p-subshell whereas chlorine has seven electrons in its 3p-subshell. 3p-subshell is relatively larger than 2p-subshell. Therefore, repulsion among the electrons will be more in the 2p-shell of fluorine than 3p-subshell in chlorine. Due to the smaller size and thus, the greater electron-electron repulsions, fluorine will not accept an incoming electron with the same as chlorine.
The reaction s that are redox reactions are
4Li(s) +O2 (g)→ 2Li2O (s)\
Mg(s) + Fe2+ (aq)→ Mg2+(aq) + Fe(s)
<h3>Explanation</h3>
A redox reaction involve both oxidation and reduction. During redox reaction there is change in oxidation states. For example in
4Li +O2 →2Li2O Li is oxidized while O is reduced
in Mg +Fe2+ → Mg2+ +Fe Mg is oxidized since it move from oxidation state 0 to 2+ while Fe2+ is reduced since it move from oxidation state of 2+ to 0
The answer is A. Destroys them

Hello!</h2>
The answer is:
The correct option is option C.
<h2>
Why?</h2>
To calculate the volume of the gas sample, we need to use the Ideal Gas Law, this equation is used to relate the pressure, the volume, the mass and the temperature of a gas, so, we can isolate the volume from it.
The Ideal Gas Law equation is equal to:
Where,
P is the pressure (in atm)
V is the volume (in liter)
n is the mass of the gass (in mole)
T is the temperature of the gass (absolute temperature)
So, from the statement we know that:
Then, substituting and calculating we have:
Now, rounding to the nearest whol number we have that the volume is equal to 36 L.
Hence, the correct option is option C.
Have a nice day!
hey! you can observe the difference in your daily routine! they're the different phases of water. at below 0°C, it occurs as ice-solid form(mostly), upto 100°C liquid form of water, above that range, water will be seen as steam- vapour phase of water! if you have further queries, do ask in the comments!
