Answer: 15.4 kJ
Explanation:
Molar mass of CH2Cl2,
MM = 1*MM(C) + 2*MM(H) + 2*MM(Cl)
= 1*12.01 + 2*1.008 + 2*35.45
= 84.926 g/mol
Mass(CH2Cl2) = 41.4 g
Use:
number of mol of CH2Cl2,
n = mass of CH2Cl2/molar mass of CH2Cl2
= (41.4 g)/(84.93 g/mol)
= 0.4875 mol
Given:
ΔH = 31.6 KJ/mol
= 31600 J/mol
Use:
Q = ΔH * number of mol
= 31.6 KJ/mol * 0.4875 mol
= 15.4 KJ
Therefore, it takes 15.4 kJ of energy to vaporize 41. 4 g of CH₂Cl₂ at its boiling point
Millington materials is a leading supplier of building equipment, building products, materials, and timber for sale, with over 200 branches across the mid-south. on january 1, 2021, management decided to change from the average inventory costing method to the fifo inventory costing method at each of its outlets. the following table presents information concerning the change. the income tax rate for all years is 25%. income before income tax fifo average cost difference before 2020 $ 30 million $ 16 million $ 14 million 2020 16 million 10 million 6 million 2021 20 million 18 million 2 million required: 1. prepare the journal entry to record the change in accounting principle. 2. determine the net income to be reported in the 2021–2020 comparative income statements. 4. indicate the affect of the change in the 2021–2020 comparative statements of shareholders’ equity assuming cash dividends were $2 million each year and that no dividends were paid prior to 2020.
The net income to be reported in the 2021–2020 comparative income statements is $15 million and $12 million.
How to calculate the net income?The journal entry to record the change in accounting principle will be:
Inventory = $20 million
Income tax payable = $5 million.
Retained earnings = $15 million
Also, the net income in 2020 will be:
= $16 - (25% × $16)
= $16 - $4.
= $12 million
The net income in 2021 will be:
= $20 - (25% × $20)
= $20 - $5
= $15 million.

You have $750 in your savings account. You owe your brother $30 and your mom $75. What is your current net worth?
Answer is 25
Explanation:
30/750
Based on the given information, the net worth is $645 when you have $750 in your savings account.
What is a saving account?A savings account is a fundamental kind of investment product that enables you to store your money and often earn a tiny bit of interest. A savings account is a bank account created to house money you don't intend to spend right away.
The net worth of any individual is calculated as the value of your assets less your obligations. Entire assets minus total liabilities to get the amount of net worth.
To calculate net worth
Balance in your savings account = $750
Liabilities:
amount from Brother = $30
amount from Mom = $75
Total liabilities = $105
Net worth = assets - liabilities
= $750 - $105
= $645
Therefore, the total net worth or equity is $645.

A teacher bought markers at a cost of $3 per set. The teacher had a $2-off coupon to use toward the total cost of the markers bought
Answer: A
Explanation:
if we look at the chart for A,
in the first row...
we see that the teacher brought 3 sets of markers.
If 1 set is $3, then 3 sets is $9 (<-- 3*3).
Now we know that the teacher has a $2-off coupon, so 9 - 2 = $7
we will repeat this with 12 sets
in the third row...
If 1 set is $3, then 12 sets is $36 (<--12*3)
We will use now the teacher's $2-off coupon, so 36 - 2 = $34
these values are correctly shown on chart A, therefore the correct answer is
