The concentration of ozone in ground-level air can be determined by allowing the gas to react with an aqueous solution of potassium iodide, ki, in a redox reaction that produces molecular iodine, molecular oxygen, and potassium hydroxide.
Answer:
a) 2KI + O₃ + H₂O ----> I₂ + O₂ + 2KOH
b) Ozone concentration = 0.246 ppb
Explanation:
Concentration of O₃ in air in ppb = 2.46/10 = 0.246 ppb
Initial-rate data at a certain temperature is given in the table for the reaction c2h5cl(g) ⟶ c2h4(g) + hcl(g) [c2h5cl]0 (m) initial rate (m/s) 0. 100 0. 630 x 10-30 0. 200 1. 26 x 10-30 0. 300 1. 89 x 10-30 determine the value and units of the rate constant.
The value of the rate constant is : 0.63 * 10⁻²⁹ s⁻¹ and The unit of the rate constant is : sec⁻¹
The chemical reaction :
C₂H₅Cl ------> C₂H₄(g) + HCl(g)
Determine the value and unit of the rate constant ( K )let the rate of reaction be expressed as
R = k [ C₂H₅Cl ]ⁿ ---- ( 1 )
where : n = order
k = rate constant
From the table
2 = 2ⁿ
therefore n = 1
Hence we can rewrite equation ( 1 ) as
R = k [ C₂H₅Cl ] ¹ ( first order reaction ) ---- ( 2 )
Next step : substitute the value of C₂H₅Cl and initial rate into equation 2
0.630 * 10⁻³⁰ = k ( 0.1 ) ¹ M
Therefore : K = 0.630 * 10⁻²⁹ s⁻¹
Hence we can conclude that The value of the rate constant is : 0.63 * 10⁻²⁹ s⁻¹ and The unit of the rate constant is : sec⁻¹.

How much charge is needed in the electrolysis of molten cabr2 using a current of 30. 0 a for 10. 0 hours?.
The amount of charge is needed in the electrolysis of molten cabr2 is 1.08 * 10⁶ C
Charge
Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field.
Charge can either be positive or negative.
Charge (Q) is given by:
Q = It
where I is the current and t is the time.
I = 30 A, t = 10 hr = (10 * 60 * 60)s = 36000 s
Q = 30(36000) = 1.08 * 10⁶ C

A factory manager selected a random sample of parts produced on an old assembly line and a random sample of parts produced on a new assembly line. The difference between the sample proportion of defective parts made on the old assembly line and the sample proportion of defective parts made on the new assembly line (old minus new) was 0. 6. Under the assumption that all conditions for inference were met, a hypothesis test was conducted with the alternative hypothesis being the proportion of defective parts made on the old assembly line is greater than that of the new assembly line. The p-value of the test was 0. 18.
Considering the p-value of the test, it is found that there is not enough evidence to conclude that the proportion of defective parts made on the old assembly line is greater than that of the new assembly line.
What are the hypothesis tested?At the null hypothesis, it is tested that the proportion of defective parts made on the old assembly line is not greater than that of the new assembly line, that is:
[tex]H_0: p_O = p_N[/tex]
At the alternative hypothesis, it is tested if the proportion is greater, that is:
[tex]H_1: p_O > p_N[/tex]
What is the decision?The p-value is greater than the standard significance level of 0.05, hence we do not reject the null hypothesis, that is, there is not enough evidence to conclude that the proportion of defective parts made on the old assembly line is greater than that of the new assembly line.

Consider a disk that rotates at 3600 rpm. The seek time to move the head between adjacent tracks is 2 ms. There are 32 sectors per track, which are stored in linear order from sector 0 through sector 31. The head sees the sectors in ascending order. Assume the read/write head is positioned at the start of sector 1 on track 8. There is a main memory buffer large enough to hold an entire track. Data is transferred between disk locations by reading from the source track into the main memory buffer and then writing the data from the buffer to the target track. A. How long will it take to transfer sector 1 on track 8 to sector 1 on track 9? b. How long will it take to transfer all the sectors of track 8 to the corresponding sectors of track 9?.
Answer:
19.71 ms
Explanation:
The disk rotates at 3600 rpm, hence the time for one revolution = 60 / 3600 rpm = 16.67 ms.
Hence time to read or write on a sector = time for one revolution / number of sectors per track = 16.67 ms / 32 sectors = 0.52 ms
Head movement time from track 8 to track 9 = seek time = 2 ms
rotation time to head up sector 1 on track 8 to sector 1 on track 9 = 16.67 * 31/32 = 16.15 ms
The total time = sector read time +head movement time + rotational delay + sector write time = 0.52 ms + 2 ms + 16.15 ms + 0.52 ms = 19.19 ms

Displayed to the right are two carts connected by a cord that passes over a small frictionless pulley. Each cart rolls freely with negligible friction. Consider the mass of the cart to be m1 and the angle the first cart sits on to be θ1, while the mass of the second cart as m2 and the angle it sits on to be θ2.
The acceleration is given by the tension in the rope and the component
of the component of the weight acting along the plane.
Response:
[tex]The \ expression \ for \ the \ acceleration, \ a \ is\ \underline{a = \dfrac{m_2 \cdot g \cdot sin \left(\theta_2 \right) - m_1 \cdot g \cdot sin \left(\theta_1 \right) }{m_1 + m_2}}[/tex]
How can the expression for the acceleration be derived?A possible question is the expression for the acceleration, a in terms of the mass, m₁, m₂, and the angles θ₁ and θ₂.
The drawing representing the situation, obtained from a similar question and created with MS Visio, is attached
From the drawing, we have;
By equilibrium of forces, the tension in the cable, T, is given as follows;
For the cart, m₁; T = m₁·a + m₁·g·sin(θ₁)
For the cart, m₂; T = m₂·g·sin(θ₂) - m₂·a
Where;
a = The acceleration that the two carts experience
Equating both values of T gives;
m₁·a + m₁·g·sin(θ₁) = m₂·g·sin(θ₂) - m₂·a
m₁·a + m₂·a = m₁·g·sin(θ₁) - m₂·g·sin(θ₂)
The
[tex]a = \mathbf{\dfrac{m_2 \cdot g \cdot sin \left(\theta_2 \right) - m_1 \cdot g \cdot sin \left(\theta_1 \right) }{m_1 + m_2}}[/tex]
The acceleration, a, that the two carts experience in terms of m₁, m₂, θ₁, θ₂,
is therefore;
