Answer:A
Explanation:
Because the water at first was not cold or warm and you want to warm it up and it’s gonna obviously be on a bowl so the taste of the bowl has a type of chemical and when you boil the water it is going to go to absorb
the water
Hello!
Determine the mass of 5.20 moles of C6H12 (gram-formula mass = 84.2 grams/mole).
We have the following data:
m (mass) = ?
n (number of moles) = 5.20 moles
MM (Molar mass of C6H12) ≈ 84.2 g/mol
Now, let's find the mass, knowing that:
![n = \dfrac{m}{MM}](https://tex.z-dn.net/?f=n%20%3D%20%5Cdfrac%7Bm%7D%7BMM%7D)
![5.20\:\:\diagup\!\!\!\!\!\!\!mol = \dfrac{m}{84.2\:g/\diagup\!\!\!\!\!\!\!mol}](https://tex.z-dn.net/?f=5.20%5C%3A%5C%3A%5Cdiagup%5C%21%5C%21%5C%21%5C%21%5C%21%5C%21%5C%21mol%20%3D%20%5Cdfrac%7Bm%7D%7B84.2%5C%3Ag%2F%5Cdiagup%5C%21%5C%21%5C%21%5C%21%5C%21%5C%21%5C%21mol%7D)
![m = 5.20*84.2](https://tex.z-dn.net/?f=m%20%3D%205.20%2A84.2)
![\boxed{\boxed{m = 437.84\:g}}\end{array}}\qquad\checkmark](https://tex.z-dn.net/?f=%5Cboxed%7B%5Cboxed%7Bm%20%3D%20437.84%5C%3Ag%7D%7D%5Cend%7Barray%7D%7D%5Cqquad%5Ccheckmark)

Explanation:
The given reaction is as follows.
![2SO_{2} + O_{2}(g) \rightarrow 2SO_{3}(g)](https://tex.z-dn.net/?f=2SO_%7B2%7D%20%2B%20O_%7B2%7D%28g%29%20%5Crightarrow%202SO_%7B3%7D%28g%29)
Value of equilibrium constant is given as
= 4.3 \times 10^{6}[/tex].
Concentration of given species is
= 0.010 M;
= 10.M;
= 0.010 M.
Formula for experimental value of equilibrium constant (Q) is as follows.
Q =
Putting the given concentration as follows.
Q =
Q = ![\frac{(10)^{2}}{(0.010)^{2}(0.010)}](https://tex.z-dn.net/?f=%5Cfrac%7B%2810%29%5E%7B2%7D%7D%7B%280.010%29%5E%7B2%7D%280.010%29%7D)
Q = ![10^{8}](https://tex.z-dn.net/?f=10%5E%7B8%7D)
It is known that when Q >
, then reaction moves in the backward direction.
When Q <
, then reaction moves in the forward direction.
When Q =
, then reaction is at equilibrium.
As, for the given reaction Q >
then it means reaction moves in the backward direction.
Thus, we can conclude that the reaction is moving in the backward direction, that is, right to left to reach the equilibrium.
Answer:
The mass stays the same only volume changes, the volume decreases
Explanation:
The ice shrinks (decreases volume) and becomes more dense. The weight will not (and cannot) change.
Hey there!
To find the density of an object, you must use this formula:
Density=Mass/Volume
Knowing that your mass is 128.3741, the only information you need left would be to find the volume of the cube.
Because the side length of the cube is given, you can multiply the length three times in order to find its volume:
1.25*1.25*1.25
=1.953125
Now that you have your volume and mass, divide the mass by the volume to find the density:
128.3741/1.953125
=65.7275392
Therefore, your density would be 65.7275392 grams per inches cubed.
