Answer:
Matter is the "stuff" that makes up the universe everything that takes up space and has mass is matter.
All matter is made up of atoms, which are in turn made up of protons, neutrons and electrons
Answer:
Even though the two substances possess many similarities, they have some unique properties. In turn, since they have the same properties, if they were the same substance, it would make matters worse, if the same chemical was in two different places, there would not be a difference between them since they are the same, just as it is with are two different chemicals would have differing properties since they are two properties would vary from one another since they are 2 totally different things!
Answer:
The value of
is 0.02495.
Explanation:
Initial concentration of
gas = 0.675 M
Initial concentration of
gas = 0.973 M
Equilibrium concentration of mustard gas = 0.35 M

initially
0.675 M 0.973 M 0
At equilibrium ;
(0.675-0.35) M (0.973-2 × 0.35) M 0.35 M
The equilibrium constant is given as :
![K_c=\frac{[S(CH_2CH_2Cl)_2]}{[SCl_2][C_2H_4]^2}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BS%28CH_2CH_2Cl%29_2%5D%7D%7B%5BSCl_2%5D%5BC_2H_4%5D%5E2%7D)


The relation between
and
are :
where,
= equilibrium constant at constant pressure = ?
= equilibrium concentration constant =14.45
R = gas constant = 0.0821 L⋅atm/(K⋅mol)
T = temperature = 20.0°C =20.0 +273.15 K=293.15 K
= change in the number of moles of gas = [(1) - (1 + 2)]=-2
Now put all the given values in the above relation, we get:


The value of
is 0.02495.
The correct answer is "Greater at 72 °F " hope it helps
It is B because horn coals are bigger and I read it in a book
