Explanation:
using Boyles law: which shows the relationship between pressure and volume, when temperature Is kept constant
P1V1 = P2V2
2 x 7.2 = 0.5 x V2
14.4 = 0.5 x V2
V2 = 14.4/0.5 = 28.8 L
Hence the new size of the balloon in litres is 28.8
Answer:
The vapor pressure in solution is 0,0051 atm
Explanation:
This is the formula for vapor pressure lowering, the colligative property.
P vapor = Pressure sv pure . Xsv
Where Xsv is data.
Xsv means Molar fraction (moles solvent/total n° moles)
Vapor pressure of water, pure is 17.5 mmHg
P vapor = 0,0313 atm . 0163
P vapor in solution = 0,0051 atm
Molar fraction does not have units
A solution will have less vapor pressure than that observed in the pure solvent.
Answer: Anion. The resulting of losing or gaining electrons would be Anion.
Answer:
Option-B (k) is the correct answer.
Explanation:
As we know the rate of reaction is given as;
Rate = k [A]ˣ
Where;
Rate = Rate of Reaction
k = rate constant
[ ] = concentration of A
x = order of reaction
So, from this equation we found that rate of reaction depends upon concentration and rate constant (k).
Now,
The rate constant is as follow,,
k = Ae^(Ea/RT)
This equation is known as Arrhenius Equation, according to this equation rate constant depends upon Temperature and Activation energy. Greater the temperature greater is the rate constant and hence greater is the rate of reaction. Or smaller the activation energy greater is the rate constant and vice versa.
