Answer:

V = 18,493.5114 cm³

Explanation:

Dimensions are;

L = 35 inches

W = 35 cm

H = 0.065 yards

Now, volume is given by;

V = LWH

But our dimensions need to all be in the same unit, so let's convert to cm.

L = 35 inches = 35 × 2.54 cm = 88.9 cm

H = 0.065 yards = 0.065 × 91.44 = 5.9436 cm

Thus;

V = 88.9 × 35 × 5.9436

V = 18,493.5114 cm³

A 0.020 M solution of niacin has a pH of 3.26. (a) What percentage of the acid is ionized in this solution
mariarad [96]

Answer: 2.75%

Explanation:

pH=-log [H+]

3.26 = -log [H+]

[H+] = 5.495\times 10^{-4} M

HA\rightleftharpoons H^++A^-

initial      0.020     0           0

eqm        0.020 -x    x      x

K_a=\frac{[H+][A-]}{[HA]}

K_a=\frac{[x][x]}{[0.020-x]}

x=5.495\times 10^{-4}

K_a=\frac{[5.495\times 10^{-4}]^2}{[0.020-5.495\times 10^{-4}]}

K_a =1.553\times 10^{-5}

percent dissociation = \frac{[H^+_eqm]}{[Acid_{initial}]}\times 100

percent dissociation=\frac{5.495\times 10^{-4}}{0.020}\times 100

Thus percent dissociation= 2.75 %

A balloon filled with 0.500 L of air at sea level is submerged in the water to a depth that produces a pressure of 3.25 atm. Wha
mario62 [17]

Answer:

Option a . 0.154L

Explanation:

P₁ . V₁ = P₂ . V₂

when we have constant temperature and constant moles for a certain gas.

At sea level, pressure is 1 atm so:

0.5 L . 1atm = V₂ . 3.25 atm

(0.5L . 1atm) / 3.25 atm = 0.154 L
