Answer:

the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes

Compounds A and B react to give a single product, C. Write the rate law for each of the following cases and determine the units
emmasim [6.3K]

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}...

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.

Using a spectrophotometer, and a cuvette with a path length of 1 cm you measure the absorbance (A275) of Guanosine to be 0.70. C
Anton [14]

Answer : The concentration of guanosine in your sample is, 8.33\times 10^{-5}M

Explanation :

Using Beer-Lambert's law :

A=\epsilon \times C\times l

where,

A = absorbance of solution  = 0.70

C = concentration of solution = ?

l = path length = 1.00 cm

\epsilon = molar absorptivity coefficient guanosine  = 8400M^{-1}cm^{-1}

Now put all the given values in the above formula, we get:

0.70=8400M^{-1}cm^{-1}\times C\times 1.00cm

C=8.33\times 10^{-5}M

Thus, the concentration of guanosine in your sample is, 8.33\times 10^{-5}M

A runner can run at a speed of 4km/h in 2 hours. What distance will she
damaskus [11]

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 emission spectrum of sodium is shown below. What do the two bright
julia-pushkina [17]

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.

10. What is the atmospheric pressure if the partial pressures of nitrogen, oxygen, and
sashaice [31]

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
