The value of entropy change (δs°) for this chemical reaction is equal to -620.4 J/molK.
What is entropy change?The entropy change of a chemical reaction can be defined as the difference between the total entropy change that is associated with the products and the total entropy change for the reactants.
In Chemistry, the standard entropy of formation for the given chemical compounds and element are:
[tex]S_{O^2}= 205\;J/molK[/tex]
[tex]S_{C_2H_6}= 229.6\;J/molK[/tex]
[tex]S_{H_2O}= 69.9\;J/molK[/tex]
[tex]S_{CO_2}= 213.6\;J/molK[/tex]
Mathematically, the entropy change of a chemical reaction is given by this expression:
[tex]\Delta S_{rxn}=\sum [n \times products]-\sum [n \times reactants]\\\\\Delta S_{rxn}=\sum [4S_{CO_2}+ 6S_{H_2O}]-\sum [2S_{C_2H_6}+ 7S_{O_2}]\\\\\Delta S_{rxn}=\sum [(4\times 213.6) + (6 \times 69.9)]-\sum [(2\times 229.6) + (7 \times 205)]\\\\\Delta S_{rxn}=\sum [854.4 + 419.4]-\sum [459.2 +1435]\\\\\Delta S_{rxn}=\sum [1273.8]-\sum [1894.2]\\\\\Delta S_{rxn}=-620.4\;J/molK[/tex]

Suppose that 30% of a population carries a certain gene. you want to estimate the probability that it will take at least a sample of four to find a person that carries the gene, how could you simulate a person having or not having the gene?
Answer:
A
Explanation:
Since only 30% of the population carries the gene, that would mean 70% doesn't carry it. Since you are using 10 digits for this experiment (0-9) this would mean that 0-2 would carry the gene (this equals 30%) and 3-9 would not (70%)
The number v of computers infected by a computer virus
The number of hours that the computers will be infected by a computer virus is one hour.
How can computers be infected by viruses?Viruses are known to be some forms of computer worms or trojans that can be spread through a system in a lot of ways.
Its spread can be through networks, discs, email attachments etc. It is one that gives others access to your computer.
The number v of computers infected by a computer virus is given by V(t) = 100e^(4.666t)
So therefore, t is the time in hours.
After 1 hour the number of computer infected v(t=1) = 100*e^(4.666*1)
=100*e^4.666

Find the amount applied to principle for the third month of a 4-year loan of $ which charges percent compounded monthly with monthly payments.
The amount applied to the principal for the third month of a 4-year loan of $50,000 at an interest rate of 10% per year with monthly payments is $865.71.
What is the amount of payment applied to the principal?The amount of the payment applied to the principal in any payment period is the total payment less the interest amount for the payment period.
For example, in this case, the periodic payment is $1,268.13. However, the interest amount for the month is $402.42 ($48,289.98 x 10% x 1/12).
The amount of the payment applied to the principal is $865.71 ($1,268.13 - $402.42).
This can be computed using an online finance calculator that calculates the periodic payment and prepares a monthly payment schedule as below.
Data and Calculations:N (# of periods) = 48 (4 x 12)
I/Y (Interest per year) = 10%
PV (Present Value) = $50,000
FV (Future Value) = $0
Results:
PMT = $1,268.13
Sum of all periodic payments = $60,870.20
Total Interest = $10,870.20
Monthly Schedule
Period PV PMT Interest Principal FV
1 $50,000.00 $1,268.13 $416.67 $851.46 $49,148.54
2 $49,148.54 $1,268.13 $409.57 $858.56 48,289.98
3 $48,289.98 $1,268.13 $402.42 $865.71 $47,424.27
Thus, the amount of the payment applied to the principal is $865.71.

Suppose that the rabbit population on mr. jenkins' farm follows the formula
Jenkins' farm tracks the procedure p(t)=3000tt+1. where t≥0 is the period (in months) since the start of the year.
As time (t) increases, the rabbit population (p(t)) will also increase, but it will approach a maximum value without ever actually reaching it, resulting in continuous growth that slows down over time.
We have,
Given formula: p(t) = 300t / (t + 1)
As time (t) increases, the denominator (t + 1) also increases.
The rabbit population (p(t)) is calculated by dividing 300t by (t + 1).
Now, let's examine the behaviour as t becomes larger:
When t is very small (close to 0), the population p(t) is also small, since the denominator (t + 1) is close to 1.
As t increases, the denominator (t + 1) grows, causing the value of p(t) to increase.
However, the rate of increase slows down as t gets larger.
This is because the denominator grows faster than the numerator (300t).
Eventually, as t becomes very large, the value of p(t) approaches but never quite reaches a maximum value.
This behaviour is characteristic of a rational function where the numerator's growth is outpaced by the denominator's growth, resulting in an asymptotic approach to a certain value.
Thus,
As time (t) increases, the rabbit population (p(t)) will also increase, but it will approach a maximum value without ever actually reaching it, resulting in continuous growth that slows down over time.

Alice says she can find the area of the room by dividing
I found the complete problem.
If Alice divides it into two trapezoids, the area formula would be: A = [(a+b) / 2] * h
Trapezoid 1
A = [(7.5 + 15)/2 * 5
A = (22.5/2) * 5
A = 11.25 * 5
A = 56.25 sq. ft
Trapezoid 2
A = [(5 + 10)/2 * 7.5
A = (15/2) * 7.5
A = 7.5 * 7.5
A = 56.25 sq. ft
Total area = 56.25 + 56.25 = 112.50 sq. ft.

A jar contains five black balls and seven white balls. two balls are drawn sequentially, but the first ball is replaced before the second drawn. the probability of drawing two white balls, given that at least one of the balls is white, is 7/17.
The probability both balls are black, given that the first one is black, is gotten as; ⁵/₁₂
What is the probability of Selection?
By using the probability of an event formula,
There are 5 black balls out of a total of 12 balls, so the probability of obtaining a black on a single draw is ⁵/₁₂, and the probability of obtaining a white is ⁷/₁₂
Since the balls are drawn with replacement, the two draws are independent events.
Use Multiplication and Union Rules to obtain the following probability:
P(F) = P(B, B) + P(B, W)
P(F) = (⁵/₁₂ * ⁵/₁₂) + (⁵/₁₂ * ⁷/₁₂)
P(F) = ⁵/₁₂
