Answer:
Explanation:
Rate laws are mathematical expressions which define the relationship that exists between the rate of a chemical reaction and the concentration of the reacting components. Rate laws take the following form:
![rate = k [A]^{x} [B]^{y} [C]^{z}](https://tex.z-dn.net/?f=rate%20%3D%20k%20%5BA%5D%5E%7Bx%7D%20%5BB%5D%5E%7By%7D%20%5BC%5D%5E%7Bz%7D)
...
where k = rate constant
[A], [C] and [C] represent the molar concentrations of the reactants
k, x, y, and z are determined experimentally by observing how the rate of reaction changes with the concentrations of the reactants.
If x=1, the reaction is first order for [A]. Also, if y=2, the reaction is second order for [B] and so on...
The overall order of the reaction is the sum of the orders with respect to each reactant. Therefore, the overall order of the reaction is x+y+z.
Answer : The concentration of guanosine in your sample is, 
Explanation :
Using Beer-Lambert's law :
where,
A = absorbance of solution = 0.70
C = concentration of solution = ?
l = path length = 1.00 cm
= molar absorptivity coefficient guanosine = 
Now put all the given values in the above formula, we get:
Thus, the concentration of guanosine in your sample is,
Answer:
Distance cover = 8 km
Explanation:
Given:
Speed of runner = 4 km/h
Time taken = 2 hour
Find:
Distance cover
Computation:
Distance = Speed x Time
Distance cover = Speed of runner x Time taken
Distance cover = 4 x 2
Distance cover = 8 km
The two lines show that these are the only two lines that do not cause energy transition in the sodium atom. Option D
<h3>What are the two lines in the spectrum of sodium atom?</h3>
The spectrum of the sodium atom appears as a doublet. This implies that there are two lines in the spectrum and they appear as bright yellow lines that are not spaced apart in the spectrum.
The two bright yellow vertical lines in the spectrum shows that these are the only two lines that do not cause energy transition in the sodium atom.

Answer:
1.009 atm is the total pressure for the mixture
Explanation:
To determine the total pressure in atm, of the three gases (N₂, O₂ and Ar) we have to sum all the values.
Sum of partial pressures in a mixture = Total pressure
First of all, we need to convert the values from mmHg to atm
604.5 mmHg . 1atm / 760 mmHg = 0.795 atm
162.8 mmHg . 1atm / 760 mmHg = 0.213 atm
0.500 mmHg . 1atm / 760 mmHg = 6.58×10⁻⁴ atm
Partial pressure N₂ + Partial pressure O₂ + Partial pressure Ar = Total P
0.795 atm + 0.213 atm + 6.58×10⁻⁴ atm = 1.009 atm
