Butyric acid ( c3h7cooh) is a weak acid . what is the ph of a 0.0250 m solution of this acid. ka = 1.5 x 10-5 (2 decimal places)
Wewaii [24]

The pH of the weak acid is 3.21

Butyric acid is known as a weak acid, we need the concentration of [H+] formula of weak acid which is given by this equation :

[H^{+}]=\sqrt{Ka . Ma}

where [H+] is the concentration of ion H+, Ka is the weak acid ionization constant, and Ma is the acid concentration.

Since we know the concentration of H+, the pH can be calculated by using

pH = -log[H+]

From question above, we know that :

Ma = 0.0250M

Ka = 1.5 x 10¯⁵

By using the equation, we can determine the concentration of [H+]

[H+] = √(Ka . Ma)

[H+] = √(1.5 x 10¯⁵ . 0.0250)

[H+] = 6.12 x 10¯⁴ M

Substituting the value of [H+] to get the pH

pH = -log[H+]

pH = -log(6.12 x 10¯⁴)

pH = 3.21

Hence, the pH of the weak acid c3h7cooh is 3.21

a taxi cab charges $4.25 for the first mile and$1.50 for each additional mile. what is the taxi rate for 12 miles
PtichkaEL [24]
$4.25 + $1.50 = $5.75= 2 miles
10 x $1.50 = $15.00=10 miles
10 + 2 = 12 miles
$5.75 + $15.00 = $20.75

Solve the system of equations below by graphing them with a pencil and paper. Choose the correct ordered pair (b, u).
Cloud [144]
U = -b + 21 . . . (1)
u = -2b + 30 . . . (2)
Equating (1) and (2),
-b + 21 = -2b + 30
-b + 2b = 30 - 21
b = 9
u = -9 + 21 = 12

Therefore, (b, u) = (9, 12).

Cards are drawn from a standard 52-card deck until the third club is drawn. After each card is drawn, it is put back in the deck
OLEGan [10]

Answer:

Step-by-step explanation:

Given that cards are drawn from a standard 52-card deck until the third club is drawn.

With replacement:

Drawing 3 club prob = 1/52 and non club = 51/52

a) Hence Prob (3rd club is drawn on the 8th selection)

= P(7 non 3 clubs, and one 3 club)

= (\frac{51}{52} )^7 (\frac{1}{52})

b) P(first 7 cards  non 3 club) = (\frac{51}{52} )^7

With replacement

c) P(7 non 3 clubs and 8th 3club)

= \frac{51C7 }{52C8}

d) P(atleast first 7 cards non3 club) =1-P(3 club in the 7th draws )=1-\frac{51C7 }{52(52C8)}
