Rick has taken a loan of $3,200 from the bank to buy new appliances. His first loan payment is due at the end of this month. He

has 24 months to pay off his loan, starting this month. The loan will be compounded monthly at a fixed annual rate of 4.8%.
Use the formula for the sum of a finite geometric sequence to determine Rick's approximate monthly payment.


Rick's approximate monthly payment will be $293.48.

Rick's approximate monthly payment will be $81.27.

Rick's approximate monthly payment will be $128.

<u>Answer:</u>

Monthly payment of Rick  will be  approximately $ 140.87

<u>Explantion:</u>

GIVEN :

Loan amount P=\$ 3,200

Time duration for loan repayment n=24 \mathrm{months}

Rate of interest  k=4.8 \% \text { per anuum }

To find:

Rick's monthly payment will be  approximately $140.87  

Solution:

Using  sum of a finite geometric sequence:

a=P\left[\frac{[1-r]}{\left[r-r^{n+1}\right]}\right]

where  r=\frac{1}{1+i}

             i=  monthly interest

but we rate of interest per annum K = 4.8%

now , rate of interest per month, i=\frac{4.8}{12}=0.4 \%=\frac{0.4}{100}=0.004

lets find the value of r

r=\frac{1}{1+i}

r=\frac{1}{1.004}        

r=0.995                                                             substituting the values,

a=P\left[\frac{1-r}{r-r^{n+1}}\right]

a=3200\left[\frac{1-0.995}{0.995-0.995^{25}}\right]

a=3200\left[\frac{0.005}{0.995-0.882}\right]

a=3200\left[\frac{0.005}{0.118}\right]

a=3200[0.044]

a=140.8

Result :

Hence the  approximate monthly payment of  Rick  is  $140.87

A 5.32 g mixture contains both lithium fluoride, LiF, and potassium fluoride, KF. If the mixture contains 3.12 g fluorine, what
bulgar [2K]

Answer:

The mass of KF in the mixture is 2.77 gms.

Explanation:

Given;

Total weight of mixture (LiF+KF)=5.32gms

Let, mass of KF in the mixture = x gms

⟹ mass of LiF in mixture =(5.32-x)gms.

We know that :

Atomic weight of F=19gms.

Atomic weight of Li =7gms.

Atomic weight of K = 39 gms.

moles=mass/(molecular weight)

Thus, moles of KF=x/58

and moles of LiF = (5.97-x)/26LiF=(5.97−x)/26

Thus,

moles of F in KF=moles of KF=x/58 ---(1)

moles of F in LiF =moles of LiF= (5.32-x)/26---(2)

From (1) & (2),

Total moles of Fluorine

=(x/58)+((5.32-x)/26)

Hence,

total weight of Fluorine in sample = moles*Atomic weight

=((x/58)+((5.32-x)/26))*19gms.

=3.12 gms.---(given)

Now, solving the equation for x,

26x +(5.32*58)-58x

=3.12*58*26/19

22x=308.56-247.62

x=60.94/22

=2.77 gms. (Answer)

Thus, the mass of KF in the mixture is 2.77 gms.

How many grams of hydrogen chloride can be produced from 1g of hydrogen and 55g of chlorine? What is the limiting reactant?
vova2212 [387]

Answer:

The limiting reactant is hydrogen, and the grams HCl produced is 36.175 g.

Explanation:

Balanced equation is 2 H + Cl2 = 2 HCl.

First thing, convert grams to moles via using molar mass.

Molar mass for hydrogen is 1.0079 g/mol. 1g x 1 mol / 1.0079 g = 0.99216 mol.

Molar mass for chlorine is 70.906 g/mol. 55g x 1 mol / 70.906 g = 0.7756748 mol.

Next, determine which is the limiting reactant - probably the fastest way to do it is just to take one of the reactants, say it's the limiting one, and calculate how much of the other reactant would be needed if that really was the limiting reactant, and then compare it to the actual moles of reactant available.

If hydrogen was the limiting reactant at 0.992 mol, you'd need .496 mol of Cl2 to complete the reaction.

If chloride was the limiting reactant at 0.776 mol, you'd need 1.55 mol of H to complete the reaction.

Comparing these numbers to the amounts we actually have available, the limiting reactant is hydrogen.

Once you've determined that, just plug in the amounts to the balanced equation to get the number of moles of HCL produced, which in this case, is just 0.992 mol.

Now, reverse the process that you took to get the moles of reactant, and you have the grams of product produced.

0.992 mol x 36.4609 g / 1 mol = 36.175 g.

Use Boyle’s law to complete the following:
mixas84 [53]

Answer:

The answer to your question is: 0.25 l

Explanation:

Data

P1 = 1 atm

V1 = 0.5 l

P2 =2 atm

V2 = ?

T = constant

Formula

          V1P1 = V2P2

Clear V2 from the formula

            V2 = V1P1/P2

Substitution

            V2 = (0.5)(1)/2  substitution

                  = 0.25 l       result
