A metal alloy bolt is initially at 100.0°C. It is dropped into a coffee cup calorimeter containing 50.0 g of water at a temperat

ure of 20.0°C. After stirring, the final temperature of both bolt and water is 25.0°C. Assuming no heat losses, and that the specific heat (capacity) of water is 4.18 J/(g ∙ K), what is the heat capacity of the bolt in J/K?

Answer:

the heat capacity of the bolt is 13.9 J/K

Explanation:

J/K is short of " joule per kelvin", is the international system unit of heat capacity

heat energy = (mass of substance)(specific heat)(change in temperature)

Q = mc∆T

Q = heat energy (Joules, J)

m = mass of a substance (kg)

c = specific heat (units J/kg∙K)

∆ is a symbol meaning "the change in"

∆T = change in temperature (Kelvins, K)

Heat gained by water = heat lost by copper  = Q = mC∆T = (50 g)(4.18 J/g/deg)(5 deg) = 1045 J   = C x ∆T

C = 1045 J/75 = 13.9 J/deg

he following is from the 2021 annual report of Kaufman Chemicals, Inc.: Statements of Comprehensive Income Years Ended December
o-na [289]

Answer: The answer is given below

Explanation:

An annual report is a report that is comprehensive about the activities of a company in the previous year. The aim of a company publishing its annual report is to give the shareholders and every other interested person information about activities of the company and its financial performance.

We are told that Kaufman calculated the $83 million accumulated other comprehensive income in 2021. This was calculated as the accumulated other comprehensive income in 2020 plus the change in the net unrealized gains on the AFS investments, the net of tax of $12 in 2021 plus the other net income of 2021. This can be represented mathematically as:

= $60,000,000 + $24,000,000 + (-$1,000,000)

=84,000,000 - $1,000,000

=$83,000,000

= 83 million

Consider the following: Cash in Bank - checking account of $18, 500 Cash on hand of $500. Post dated checks received totaling $3
lesya [120]

Answer:

b $19,000

Explanation:

The reconciliation between the book balance and the bank statement examines the transactions recorded in either account but omitted in the other and the transactions recorded wrongly in  both accounts.

Given the following transactions

Cash in Bank - checking account = $18, 500

Cash on hand = $500

Post dated checks received =  $3 500 and

Certificates of deposits = $24,000

Cash balance in balance sheet = $18, 500 + $500 + $24,000

= $43,000

The post dated check is not included as the cash is yet to be received. The balance in the post dated check will form part of the receivables balance and not that of cash.

The certificate of deposit may be accounted for as part of cash and cash equivalent as shown in the computation above. Where the certificate of deposit is accounted for as a short term investment,

Cash balance in balance sheet = $18, 500 + $500 = $19,000

Galvin has deposited $879 in a savings account that earns interest at a rate of 1.8% compounded quarterly.what will the account
Tju [1.3M]

$1,130.28

Formula is A = P (1 + [r/n])^(nt)

A= 879 (1+ [.018/4])^(4*14)

A= 879 (1.0045)^56

A= $1,130.28

A = future total amount

P = principle (amount initially deposited)

r = the annual interest rate (decimal)

n = times that interest is compounded per year  (quarterly is 4 times per year)

t = number of years
