![\alpha = 7.044*10^{-3](https://tex.z-dn.net/?f=%5Calpha%20%3D%207.044%2A10%5E%7B-3)
percentage% (∝) = ![7.044*10^{-3}*100](https://tex.z-dn.net/?f=7.044%2A10%5E%7B-3%7D%2A100)
= 0.704%
For Part B; where Concentration of B =
M
![\alpha = \sqrt{\frac{1.34*10^{-5}}{7.84*10^{-2}} }](https://tex.z-dn.net/?f=%5Calpha%20%3D%20%5Csqrt%7B%5Cfrac%7B1.34%2A10%5E%7B-5%7D%7D%7B7.84%2A10%5E%7B-2%7D%7D%20%7D)
![\alpha = \sqrt{1.709*10^{-4} }](https://tex.z-dn.net/?f=%5Calpha%20%3D%20%5Csqrt%7B1.709%2A10%5E%7B-4%7D%20%7D)
![\alpha = 0.0130\\](https://tex.z-dn.net/?f=%5Calpha%20%3D%200.0130%5C%5C)
percentage% (∝) = 0.0130 × 100%
= 1.30%
For Part C; where Concentration of C= ![1.92*10^{-2} M](https://tex.z-dn.net/?f=1.92%2A10%5E%7B-2%7D%20M)
![\alpha = \sqrt{\frac{1.34*10^{-5}}{1.97*10^{-2}} }](https://tex.z-dn.net/?f=%5Calpha%20%3D%20%5Csqrt%7B%5Cfrac%7B1.34%2A10%5E%7B-5%7D%7D%7B1.97%2A10%5E%7B-2%7D%7D%20%7D)

![\alpha =0.02608](https://tex.z-dn.net/?f=%5Calpha%20%3D0.02608)
percentage% (∝) = 0.02608 × 100%
= 2.60%

The balanced molecular equation for the neutralization of sodium hydroxide with sulfuric acid is:
Sodium hydroxide + Sulfuric acid → Sodium sulfate +water
<h3>What is the balanced molecular equation?</h3>
A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products. In other words, the mass and the charge are balanced on both sides of the reaction.
In the given reaction, the reactants have been sulfuric acid and sodium hydroxide. Thus, these are written on the left side of the right arrow. The sodium sulfate and water have been the products and written on the right side of the right arrow.
The balanced molecular equation for the neutralization of sodium hydroxide with sulfuric acid is:
Sodium hydroxide + Sulfuric acid → Sodium sulfate +water

Answer:
science is nothing without funding
Explanation:
Well Science in the US is highly a political affair. Scientists need funding for research, so they usually have to obtain grants from people who have the means to spare it. In many cases that means people who are involved with the government, or have close ties to it.
So scientists find themselves having to play off partisan politics in order to secure the funding they need for their research. Many times they also find that their research will inevitably get skewn to meet the original funders own ends.
Mostly what I have said is commonly known. However I am in school, and deal with scientists and doctoral researchers who have expressed and validated similar experiences.
Answer:
The correct order of increasing vapor pressure: Z,Y,X
Explanation:
It is given that the normal boiling point order of three liquids is:
![X < Y < Z](https://tex.z-dn.net/?f=X%20%3C%20Y%20%3C%20Z)
Normal Boiling point is defined as the temperature at which the vapor pressure becomes equal to the atmospheric pressure.
Vapor pressure is the pressure exerted by vapor on the surface of liquid.Hence it increases with tendency of vapor formation.
High boiling point implies that high energy is required to convert the liquid into vapor state and hence the vapor pressure reaches atmospheric pressure at higher temperatures.
Low boiling point implies that the liquid gets easily boiled at a low temperature and converts into vapor with ease and hence exert high vapor pressure.
Bottom line is vapor pressure decreases as boiling point increases at STP.
Hence the order of increasing vapor pressure is Z,Y,X
