Explanation:
nice question...
ok solution goes right the way through...
in temp 193°C the volume of gas was 892ml
so for...144°C the volume of gas will be 892/193x144=665.533 or 665.534...(rounded off)...or 665°...(approx)....so got ur answer...
I hope it helps....
please comment if you have any further questions...i will be solving it for u...

The main reason for this is Average bond of O₂ is shorter and strong from O₃.
<h3>What is ozone?</h3>
Ozone is a blue gas composed of three oxygen atoms bonded together.
It occurs naturally high up in the Earth's atmosphere, where it protects the surface from harmful ultraviolet (UV) rays,
UV radiation will dissociate ozone into an oxygen atom and an oxygen molecule.
Ozone molecules are tetrahedral so the bond angle is 109 degree the electrons in the double bond occupy more space that the non-bonding electron pair.
Oxygen has a small size that leads to smaller O-O bond length.
A lone pair of electrons on both the oxygen repel each other leading to weakening of O-O bond.
O3 has longer and weaker bonds than O2, whereas SO2 has shorter and stronger bonds than SO.
Molecular oxygen, O2, is photolyzed by light of 241 nm and has a bond energy of 498 kJ/mol.
The main reason for this is Average bond of O₂ is shorter and strong from O₃.

Answer:
3211.12 K
Explanation:
The expression for the standard change in free energy is:
Where,
is the change in the Gibbs free energy.
T is the absolute temperature. (T in kelvins)
is the enthalpy change of the reaction.
is the change in entropy.
For reaction to be spontaneous, 
Given, 
So,
Thus, applying values as:-
So, T = 3484.27 K
The conversion of T( °C) to T(K) is shown below:
T( °C) = T(K) - 273.15
So,
T = (3484.27 - 273.15) K = 3211.12 K
<u>The temperature below which the reaction is spontaneous is:- 3211.12 K </u>
Answer:
d) a pure substance that can be separated into different elements by chemical means.
Explanation:
Hello,
Sodium chloride (NaCl) is a chemical compound composed by sodium and chlorine. They are chemically bonded through a ionic bond which means that the sodium transfers just one electron (valence electron) to the chlorine to form the bond. Now, if we want to separate them, we must induce a chemical process because bond breaking implies a chemical change, not physical. Thus, a typical way to separate them (break the bond) is via electrolysis in which an electric driving force induce the aforementioned breakdown.
Best regards.
