Pt = p1 + p2 + p3, p1 = pp (CO) atm
2.68 atm = p1 + 1.56 atm + 0.65 atm
2.68 = p1 + 2.21
p1 = 2.68 - 2.21
p1 = 0.47 atm

Answer: Partial pressure of CO in the sealed vessel is 0.47 atm.

Explanation: From Dalton's law of partial pressures, "Total pressure is the sum of partial pressures of the gases present in the mixture."

So, total pressure = partial pressure of carbon monoxide + partial pressure of oxygen + partial pressure of carbon dioxide

Let's plug in the values in the formula:

2.68 atm = partial pressure of CO + 1.56 atm + 0.65 atm

2.68 atm = partial pressure of CO + 2.21 atm

partial pressure of CO = 2.68 atm - 2.21 atm

partial pressure of CO = 0.47 atm

Hence, the partial pressure of carbon monoxide gas in a sealed vessel is 0.47 atm.

A sugar crystal contains approximately 1.4×1017 sucrose (C12H22O11) molecules. What is its mass in milligrams? Express using 2 s
alekssr [168]

Answer:

From the periodic table:

mass of carbon = 12 grams

mass of hydrogen = 1 grams

mass of oxygen = 16 grams

molar mass of surcose = 12(12) + 22(1) + 11(16) = 342 grams

number of molecules = number of moles x Avogadro's number

number of moles = number of molecules / Avogadro's number

number of moles = (2.2x10^17) / (6.02x10^23) = 3.6544 x 10^-7 moles

number of moles = mass / molar mass

mass = number of moles x molar mass

= 1.7 x 10^17/6.022 x 10^23.

What is the pOH of a solution of pH 3 acid? (Kw= 1.0 x 10-14)
miv72 [106K]

Answer:

pOH = 11

Explanation:

The pH is an unit of concentration widely used in chemistry to find the quality of a solution.

To solve this question we must, as first, find the [H+] using the pH:

[H+] = 10^-pH

[H+] = 10^-3

Now, using kw:

kw = 1.0x10-14 = [H+] [OH-]

1.0x10-14 = [10^-3] [OH-]

[OH-] = 1.0x10-11

pOH = -log [OH-]

<h3>pOH = 11</h3>

Be sure to answer all parts. Write a balanced equation and Kb expression for the following Brønsted-Lowry base in water: benzoat
Cerrena [4.2K]

Answer:

The balanced reaction is:-

C_6H_5COO^-_{(aq)} + H_2O_{(l)}\rightleftharpoons C_6H_5COOH_{(aq)} + OH^-_{(aq)}

K_b expression is:-

K_{b}=\frac {\left [ C_6H_5COOH \right ]\left [ {OH}^- \right ]}{[C_6H_5COO^-]}

Explanation:

Benzoate ion is the conjugate base of the benzoic acid. It is a Bronsted-Lowry base and the dissociation of benzoate ion can be shown as:-

C_6H_5COO^-_{(aq)} + H_2O_{(l)}\rightleftharpoons C_6H_5COOH_{(aq)} + OH^-_{(aq)}

The expression for dissociation constant of benzoate ion is:

K_{b}=\frac {\left [ C_6H_5COOH \right ]\left [ {OH}^- \right ]}{[C_6H_5COO^-]}
