How can 100. ml of sodium hydroxide solution with a ph of 13.00 be converted to a sodium hydroxide solution with a ph of 12.00 ?

Answers

The solution can be evaporated such that only 10mL of the solution remains in that way, we can have a solution of pH 12.00.

What is pH?

The pH refers to the degree of acidity or alkalinity of solution. We can obtain the concentration of each solution from the pH as follows;

At pH = 13;

[OH^-] = Antilog (-13) = 1 * 10^-13 M

At pH 12

[OH^-] = Antilog (-12) = 1 * 10^-12 M

Using the formula;

C1V1 =C2V2

1 * 10^-13 M * 100 mL = 1 * 10^-12 M * VmL

VmL = 1 * 10^-13 M * 100 mL/1 * 10^-12 M

VmL = 10mL

Answers

The smallest positive integer n so that you can avoid ever having the exact same group of three members over all 365 days is; 11

How to solve probability combination?

if we have n people and we want to do groups of 5, the total number of different combinations is:

ⁿC₅ = n!/((n - 5)!5!)

By using the Brute force method, we have;

If n = 5,

c = 5,

Thus;

C₅ = 5

If n = 6,

c = 6,

Thus;

C₅ = 6

If n = 7,

c = 7,

Thus

C₅ = 21

If n = 8,

c = 8,

Then;

C₅ = 56

Now, If n = 9,

C = 9!/((9 - 5)!5!)

C = 126

We want to find the smallest n such that c > 365. Thus, C = 126 is too small.

Let's try n = 11;

C = 11!/(6! * 5!) =  462

This is greater than 365 and so we need at least 11 members in the club.

How does housman use the structure of the poem to create surprise?

Answers

The poet offers an elegy for a young, athletic man who recently passed away in "To an Athlete Dying Young." Naturally, this is a tragic subject, and the poet begins his poem with a sorrowful and solemn tone of pity. The author, on the other hand, uses the poem's structure to surprise his audience. Despite the melancholy tone of the opening line, the tone of the poem shifts to one of satisfaction and praise as the poem goes on, surprising the reader. The author can express various opposing views in each stanza. While he feels that dying young is a pity, he considers how rapidly youth fades and how many men lose their reputation by the time they reach retirement age. He says that if an athlete dies young, he will never have to deal with old age, decline, or loss of glory. Despite the melancholy, the author can draw some constructive conclusions from the incident

A driver of a 1 000 kg jeepney travelling at a speed of 16,7 m/s bound for divisoria applies the car's brakes when he sees a red light along recto avenue. the car's brakes provide a frictional force of 8 000 n. determine the stopping distance of the car.

Answers

The stopping Distance of the Car with the given parameters is; 17.43 m

What is the stopping sight distance?

We are given;

mass; m = 1 000 kg

speed; u = 16.7 m/s

Frictional force; F = 8000 N

distance, s  = ?

final velocity = 0 m/s (car stops)

Formula for final velocity is;

v² = u² + 2as

but a = negative (deceleration)

And F = ma

Thus;

a = F/m = 8000/1000

a = 8 m/s²

Thus;

0 = (16.7)² - 2(8)(s)

278.89 = 16s

Answers

Considering the given discrete probability distribution, it is found that there is a 0.36 = 36% probability that Hugo buys fewer than 3 packs.

What is the discrete probability distribution?

Researching on the internet, it is found that the discrete probability distribution for the number of packs that Hugo buys is given by:

P(X = 1) = 0.2.P(X = 2) = 0.16.P(X = 3) = 0.128.P(X = 4) = 0.512.

The probability that he buys fewer than 3 packs is given by:

P(X < 3) = P(X = 1) + P(X = 2).

Hence:

P(X < 3) = P(X = 1) + P(X = 2) = 0.2 + 0.16 = 0.36.

There is a 0.36 = 36% probability that Hugo buys fewer than 3 packs.

Rebello's preferred stock pays a dividend of $1.00 per quarter, and it sells for $55.00 per share. what is its effective annual (not nominal) rate of return?

Answers

Assuming it sells for $55.00 per share. Its effective annual (not nominal) rate of return is 7.47%.

Effective annual rate of return

Using this formula

Effective annual rate of return=[1+(Preferred quarterly dividend+Preferred stock price]^Periods per year-1

Where:

Periods per year =4

Preferred quarterly dividend=$1.00

Preferred stock price=$55.00

Let plug in the formula

Effective annual rate of return = [1+ ($1.00/$55.00)]^4 - 1

Effective annual rate of return=(1+0.018181818)^4-1

Effective annual rate of return=(1.018181818)^4-1

Effective annual rate of return =1.0747-1

Effective annual rate of return =0.0747×100

Effective annual rate of return = 7.47%
