Since there is a decrease in entropy owing to the solid product hence a large negative change in entropy is obtained.
What is entropy?The term entropy is the degree of disorder of a system. This question is incomplete but I will try to approach it in a general way. The equation of the reaction is; 2Mg(s) + O2(g)→2MgO(s).
We can see that in the reaction, the product of the process is a solid. Since a solid is rigidly arranged hence the entropy is largely decreased and a large negative change in entropy is obtained.

Ab2 is a molecule that reacts readily with water. Calculate the bond energy of the a–b bond using the standard enthalpy of reaction and the bond energy data provided. Enter a number in kj to 0 decimal places
By using the standard enthalpy of reaction, the bond energy of the (A-B) bond is equal to 152.25 kJ/mol.
The balanced chemical equation.[tex]AB_2[/tex] is a molecule that reacts readily with water ([tex]H_2O[/tex]) as represented by this properly balanced chemical equation:
[tex]2AB_2 +2H_2O \rightarrow O_2 +4HB+A_2\; \Delta H = -142\;kJ[/tex]
Bond: O–H O=O H–B [tex]A \rightarrow A^+[/tex]
Bond energy (kJ/mol): 467 498 450 321
The standard enthalpy of reaction.Mathematically, the standard enthalpy of reaction can be calculated by using this formula:
[tex]\Delta H^{\circ}_R=\Delta H_{reactants}-\Delta H_{products}[/tex]
Substituting the given parameters into the formula, we have;
[tex]-142=[(2\times2(A-B)+(2\times2(O-H)-[(O=O)+4(H-B)+(A-A)]\\\\-142=4(A-B)+4(467)-498-4(450)-321\\\\-142=4(A-B)+1868-498-1800-321\\\\4(A-B)=-142-1868+498+1800+321\\\\4(A-B)=609\\\\(A-B)=\frac{609}{4}[/tex]

Answer:

Explanation:
In a random sample of cell phones, the mean full retail price was $ and the standard deviation was $. assume the population is normally distributed and use the t-distribution to find the margin of error and construct a % confidence interval for the population mean . interpret the results.
Using the t-distribution the margin of error is 128.04 and 95% confidence interval for the population mean is:315.46; 571.54.
Confidence IntervalUsing the margin of error for a confidence interval formula
Margin of error(m) = t × (s/√n)
Where:
t=critical value for a 2 tailed test at a 5% level of significance
Degree of freedom = 10 - 1 = 9
Level of significance α = 5%
Value of t using t distribution table= 2.262
Hence:
Margin of error = 2.262 × (179/√10)
Margin of error = 128.04
95% confidence level for the population mean (u):
Confidence level =Mean ± Margin of error
Confidence level = 443.5 ± 128.04
Confidence level=(443.5 - 128.04); (443.5 + 128.04)
Confidence level= (315.46; 571.54)

A boat heading out to sea starts out at point aa, at a horizontal distance of 770 feet from a lighthouse/the shore. From that point, the boat’s crew measures the angle of elevation to the lighthouse’s beacon-light from that point to be 14^{\circ} ∘. At some later time, the crew measures the angle of elevation from point bb to be 8^{\circ} ∘. Find the distance from point aa to point bb. Round your answer to the nearest tenth of a foot if necessary
With the angle of elevation at 8 degrees and 14, the distance from point A to point B would be 596.72 feet.
How to solve for the distance in feettan < CAD = CD/AC
we have to cross multiply here so that
CD = AC * tan < CAD
AC = 770
tan < CAD = tan 14 degrees
tan < B = CD/BC
BC = CD/tab<B
= 770*tan 14/tan8
= 770*0.2493/0.1405
= 1366.72 feet
AB = BC - AC
= 1366.72 - 770
