The "REVERSIBLE" chemical reaction-
A + B <--> C + D
Kc = [C][D] / [A][B] = 6.8
Concentration at the start and after equilibrium-
[A] = 2.00 M --> (2.00 - X) M
[B] = 2.00 M --> (2.00 - X) M
[C] = 0.00 M --> X M
[D] = 0.00 M --> X M
6.8 = X^2 / (2.00 - X)^2
take the square root of both sides-
2.6077 = X / (2.00 - X)
5.2154 - 2.6077 X = X
5.2154 = 3.6077 X
X = 1.4456
at equilibrium-
[A] = 0.55 M
[B] = 0.55 M
[C] = 1.45 M
[D] = 1.45 M

Net working capital is defined as current assets divided by current liabilities.

Ahat [919]

Answer:

The answer is False.

Explanation:

False, because the net working capital is determined by subtracting all the current liabilities from the current assets. But in the question, it says net working capital is determined by dividing the current assets with current liabilities which is wrong. Therefore, if the current assent is 10000 dollars and current liabilities are 5000 dollars then net working capital is 10000 – 5000 = $5000.

The commercial bank is a financial institution that accepts deposits and offer other services such as giving loans and other basic financial services to both individuals and organisations.

Life insurance companies

The life insurance companies are financial institutions that provide lump sums otherwise known as death benefits to beneficiaries of their policy holders upon their demise, provided that premium is paid on regular basis.

Mutual fund

A Mutual Fund is an investment vehicle made up of a pool of funds collected from numerous investors for the purpose of investing in securities such as stocks, bonds, money market instruments and similar assets. Mutual Funds are operated by professional fund managers, who invest the fund's capital and attempt to produce capital gains and income for the investors.

One of the main advantages of Mutual Funds is they give small investors access to professionally managed, diversified portfolios of equities, bonds and other securities. Each shareholder, therefore, participates proportionally in the gain or loss of the fund.

bezimeni [28]

Answer:

a. Current ratio=2.105

b. Quick ratio=1.053

c. Cash ratio=0.211

Explanation:

Step 1: Determine total current assets

The total current assets can be expressed as;

T=C+R+I

where;

T=total current assets

C=cash and marketable securities

R=accounts receivable

I=inventory

In our case;

T=unknown, to be determined

C=$200,000

R=$800,000

I=$1,000,000

replacing;

T=(200,000+800,000+1,000,000)=$2,000,000

Total current assets=$2,000,000

Step 2: Determine total current liabilities

The total current liabilities can be expressed as;

T=W+A+N

where;

T=total current liabilities

W=accrued wages and taxes

A=accounts payable

N=notes payable

In our case;

T=unknown, to be determined

W=$250,000

A=$400,000

N=$300,000

replacing;

T=(250,000+400,000+300,000)=$950,000

Total current liabilities=$950,000

Step 3: Determine current ratio

The current ratio can be expressed as follows;

Current ratio=total current assets/total current liabilities

where;

Current ratio=unknown, to be determined

total current assets=$2,000,000

total current liabilities=$950,000

replacing;

Current ratio=(2,000,000/950,000)=2.105

Step 4: Determine quick ratio

The quick ratio can be expressed as follows;

Quick ratio=(current assets-inventory)/current liabilities

where;

Quick ratio=unknown, to be determined

current assets=$2,000,000

inventory=$1,000,000

current liabilities=$950,000

replacing;

Quick ratio=(2,000,000-1,000,000)/950,000

Quick ratio=1,000,000/950,000=1.053

Quick ratio=1.053

Step 4: Determine cash ratio

The cash ratio can be expressed as follows;

Cash ratio=(cash+marketable securities)/current liabilities

where;

Cash ratio=unknown, to be determined

Cash and marketable securities=$200,000

current liabilities=$950,000

replacing;

Cash ratio=(200,000/950,000)=0.211

Cash ratio=0.211
