Sodium hypochlorite, naocl, is the active ingredient in household bleach. what is the concentration of hypochlorite ion if 20.00 ml of bleach requires 32.00 ml of 0.500 m hcl to reach the equivalence point?
The concentration of hypochlorite ion if 20.00 ml of bleach requires 32.00 ml of 0.500 m hcl to reach the equivalence point is: 0.800 M.
Concentration of hypochlorite ionGiven:
Ca = concentration/molarity of acid=0.500 M
Va = volume of acid= 32.00 cm3
Cb = concentration/molarity of base=?
VB =volume of base= 20.00 cm3

The element that would be the most effective at accepting electrons from another reagent is
Answer:
Matching the elements to the appropriate blanks as follows :
1) The element that would most effective at accepting electrons is ; CI
2) The element that would be the best insulator is ; Cl
3) The element best to form an ionic compound with sulfur is ; Rb
The acceptance of electrons by elements depends on the electronegativity of the element. from the options listed the element with the highest level of electronegativity is Cl ( chlorine ) therefore it the most effective at accepting electrons
Cl ( chlorine) is a non metal and non-metals are semi-conductors or insulators. therefore Cl would act as the best insulator when compared to other elements.
when metals react with non-metals they form an ionic compound. for sulfur the best metal to react with it is Rb ( soft silvery metal ) and the reaction of Rb and sulfur in hydrogen gas. results in Rb₂S₅
Hence we can conclude Matching the elements to the appropriate blanks as follows : The element that would most effective at accepting electrons is ; CI, The element that would be the best insulator is Cl ,The element best to form an ionic compound with sulfur is ; Rb

Assume a company has two divisions, a and b. the company’s overall sales, overall contribution margin ratio, common fixed expenses, and net operating income are $500,000, 48%, $50,000, and $10,000, respectively. if division a has a contribution margin of $180,000 and division b’s contribution margin ratio is 30%, then what is division a’s sales?
The value of the sales of division A from the contribution margin ratio, and common fixed expenses given is $300,000.
How to calculate sales?
Overall sales = $500,000
Overall Contribution margin will be:
= Overall Sales x Overall Contribution margin ratio
= $500,000 x 48%;
= $240,000
Division B's Contribution margin will be :
= Overall Contribution margin less Division A's Contribution margin
= $240,000 - $180,000
= $60,000
Division B's Sales will be:
= Division B's Contribution margin/Division B's Contribution margin ratio
= $60,000/30%
= $200,000
Therefore, Division A's Sales :
= Overall Sales - Division B's Sales
= $500,000 - $200,000
= $300,000

You cook a turkey until the internal temperature reaches 180°f. the turkey is placed on the table until the internal temperature reaches 100°f, and it can be carved. when the room temperature is 72°f, the cooling rate of the turkey is $r=0.067$ . how long do you have to wait until you can carve the turkey? use newton's law of cooling to solve the problem. round your answer to the nearest whole minute.
The newton's law of cooling is used to determine the waiting time
You will have to wait for 20 minutes to carve the turkey
How to determine the time?By newton's law of cooling, we have:
[tex]T = (T_o - T_R) e^{-rt} + T_R[/tex]
From the question, we have:
T = 100°f ---- The serving temperature
To = 180°f --- The initial temperature
TR = 72°f ----- the room temperature
r = 0.067 -- the cooling rate
So, we have:
[tex]T = (T_o - T_R) e^{-rt} + T_R[/tex]
[tex]100 = (180 - 72) e^{-0.067t} + 72[/tex]
Subtract 72 from both sides
[tex](180 - 72) e^{-0.067t} = 28[/tex]
Evaluate the difference
[tex]108 e^{-0.067t} = 28[/tex]
Divide both sides by 108
[tex]e^{-0.067t} = 0.25923[/tex]
Take the natural logarithm of both sides
[tex]-0.067t = -1.3500[/tex]
Divide both sides by -0.067
[tex]t = 20.149[/tex]
Approximate
[tex]t = 20[/tex]
Hence, you will have to wait for 20 minutes to carve the turkey

The final temperature of the water after addition to the heated water at 20° C in degree kelvins' is calculated as; 295.23 K
What is the Final Temperature?We are given;
mass of the initial water; m₁ = 2.5 kg
specific heat capacity of water; c = 4189 J/kg.K
initial temperature of water; T₁ = 13.5 ⁰C
final temperature of the water; T₂ = 22.5 ⁰C
mass of the final water; m₂ = 0.5 kg
initial temperature of the final water; T₁,i = 20 ⁰C
If the system is isolated, then we have;
m₁*c*(T_f - T₂) + m₂*c*(T_f - T₁,i) = 0
c will cancel out to give;
[2.5T_f - (2.5*22.5)] + [0.5T_f - (0.5*20)] = 0
2.5T_f - 56.25 + 0.5T_f - 10 = 0

Christopher runs a farm stand that sells apples and bananas. Yesterday christopher sold 35 pounds of apples and 34 pounds of bananas for a total revenue of $163. 50. Today he sold 15 pounds of apples and 17 pounds of bananas for a total revenue of $76. 75. Determine the price of each pound of apples and the price of each pound of bananas
The equation computed shows that the price of apple is $2 and the price of banana will be $2.75.
How to compute the equation?Christopher sold 35 pounds of apples and 34 pounds of bananas for a total revenue of $163.50. This will be:.
35a + 34b = 163.50
He also sold 15 pounds of apples and 17 pounds of bananas for a total revenue of $76.75. This will be:
15a + 17b = 76.75
Equate both equations
35a + 34b = 163.50 ..... i
15a + 17b = 76.75 ...... ii
Multiply equation i by 15.
Multiply equation ii by 35
525a + 510b = 2452.50 .... iii
525a + 595b = 2686.25 .... iv
Subtract equation iii from iv
85b = 233.75
b = 233.75/85
b = 2.75.
The price of banana is $2.75.
The price of apple will be:
35a + 34b = 163.50
35a + 34(2.75) = 163.50
35a + 93.50 = 163.60
35a = 163.50 - 93.50
35a = 70
a = 70/35
