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:
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
2N2O5(g)----> 4NO2(g) + O2(g)
<span>[N2O5]i (M) Initial Rate(M^-1 s^-1) </span>
<span>0.093 4.84x10^-4 ---- (1) </span>
<span>0.186 9.67x10^-4 ----- (2) </span>
<span>0.279 1.45x10^-3 ----- (3) </span>
<span>From equation (1) & (2) it is evident that when [N2O5}i is doubled the initial rate is doubled, which implies the rate is directly proportional to [N2O5]. Similarly comparing equation (1) & (3) we observe that when [N2O5] is tripled the rate is also tripled. Hence the rate equation is </span>
<span>Rate = k [N2O5] </span>
<span>Using the data of any equation, say (1), we get </span>
<span>4.84x10^-4 = k x 0.093 </span>
<span>OR k = 4.84x10^-4/0.093 = 5.2 x 10^-3 s-1 </span>
<span>Hence the rate law is </span>
<span>Rate = 5.2 x 10^-3 s-1[N2O5]</span>

The guidelines are meant to provide all employees with a standard organizational format for information from in progress and completed lab work. Also providing easy work flow should you have stop any where in process of a lab.</span>
"Hydrochloric acid (HCl) is an example of an acid. When it dissolves in water, it produces positive hydrogen ions and negative chloride ions (Cl-). This can be represented by the chemical equation: HCl H2O→ H+ + Cl."
Hope this helps! Sorry if it doesn't.
Answer:
This process is known as doping. It can be done by adding either of two types of impurity to the crystal. (A) By adding electron rich impurities i.e., group 15 elements to the silicon and germanium of group 14 elements.
