The interest that will be paid for a period of 30 days at an interest rate of 0.039% will $0.55
<h3>Interest Rate Computation</h3>
Given Data
- Charge on purchase = $46.92
- Daily interest Rate = 0.039%
Let us find the daily amount in Interest
= 0.039/100*46.96
= 0.0182988
Hence the daily interest made will 0.018
Also, for 30 days the accrued amount will be
= 0.18*30
= 0.548964
= $0.55

a. CPAs in public practice in the US are required to apply the IESBA Code, even if they don't perform services outside the US.
b. State boards of accountancy are required to adopt the IFAC's rules within 90 days of an IESBA rule change.
c. As a member body of IFAC, the AICPA is required to change its bylaws whenever the IESBA changes its rules.
d. The AICPA is required to adopt ethics standards that are at least as restrictive as the IESBA rules.
The calculated pH of the solutions are given below:
- The pH of the solution after 14.0 ml of base is added to it is calculated as 1.45.
- The pH of the solution after 19.8 ml of base is added to it is calculated as 3.0
- The pH of the solution after 20.0 ml of base is added to it is calculated as 7.
<h3>What is pH?</h3>
This is the level of acidity or alkalinity of an aqueous solution. The pH of a substances tells if its an acid, base or neutral.
HBr and NaOH while in water would dissociate and they would become H+ and OH- respectively.
Mol of HBr = Mol * Vol
= 0.200 * 20mL
= 4 mmol
A. Moles of NaOH added
= 0.2 X 14
= 2.8 mmol
Moles of H+ that did not react
= 4 - 2.8
= 1.2 mmol
1.2/1000 = 0.0012 moles
Total volume = 20 + 14
= 34 mL to litres
= 0.034 L
Molarity of H+ = 0.0012 / 0.034L
= 0.035 M
-log[0.035] = 1.45
The pH of the solution is 1.45
B. NaOH added = 19.8 * 0.2 =
3.96 mmoles
The unreacted solution
= 4.0 - 3.96
= 0.04 mmol
0.04/1000 = 0.00004 moles
Total volume = 20 + 19.8
= 39.8mL
Converted to litres = 0.0398L
Molarity = 0.00004 / 0.0398L
= 0.001
-log(0.001) = 3.0
The ph Is therefore 3.0
C. Moles of NaOH added = 0.2*20mL = 4mmol
All the H+ are going to be consumed here. This would result into a neutral solution pH = 7

<h3> <u>
Sustainable development of society</u></h3>
Sustainable development of society involves in organizing principle to attain goals for the people enrichment and providing the "ecological ability of natural systems" to provide natural resources.
Sustainable development of the society tells us about the living conditions of the people that determines the continuation to meet the needs of humans without affecting the solidity and uprightness of the nature and ecosystem. It aims at merging the economic and environmental goals.
