that's the number in front of the molecules
Answer:
Temperature
Explanation:
Kinetic energy of gass molecules is directly propotional to the temperature.
Doxorubicin because it is one of the most powerful drugs in chemotherapy
Answer:
Formed by adding 5 g of sugar to 1 L of water
Explanation:
The substance formed by adding 5 g of suagr to 1 L of water is a mixture.
<em>A mixture is defined as two or more substances that are physically mixed but do not react together. It thus means that the component substances of a mixture can be retrieved through appropriate means of separations.</em>
<u>A mixture of sugar and water can be separated by evaporation. The mixture is heated and the vapor from the boiling water can be condensed to retrieve the water while the residue will give the sugar that was initially dissolved in it. </u>
The products formed from other descriptions in the illustration cannot be separated ordinarily and thus, are not considered to be mixture. The components have been chemically combined together.
<u>Answer:</u> The value of equilibrium constant is 0.997
<u>Explanation:</u>
We are given:
Percent degree of dissociation = 39 %
Degree of dissociation,
= 0.39
Concentration of
, c = 
The given chemical equation follows:

<u>Initial:</u> c -
<u>At Eqllm:</u>

So, equilibrium concentration of ![N_2O_4=c-c\alpha =[1-(1\times 0.39)]=0.61M](https://tex.z-dn.net/?f=N_2O_4%3Dc-c%5Calpha%20%3D%5B1-%281%5Ctimes%200.39%29%5D%3D0.61M)
Equilibrium concentration of ![NO_2=2c\alpha =[2\times 1\times 0.39]=0.78M](https://tex.z-dn.net/?f=NO_2%3D2c%5Calpha%20%3D%5B2%5Ctimes%201%5Ctimes%200.39%5D%3D0.78M)
The expression of
for above equation follows:
![K_{c}=\frac{[NO_2]^2}{[N_2O_4]}](https://tex.z-dn.net/?f=K_%7Bc%7D%3D%5Cfrac%7B%5BNO_2%5D%5E2%7D%7B%5BN_2O_4%5D%7D)
Putting values in above equation, we get:

Hence, the value of equilibrium constant is 0.997
