What is the pH of a buffer solution when the concentrations of both buffer components (the weak acid and its conjugate base) are

Ksivusya [100]

Explanation:

Considering the Henderson- Hasselbalch equation for the calculation of the pH of the buffer solution as:

pH=pKa+log[base]/[acid]

When the the concentrations of both buffer components (the weak acid and its conjugate base) are equal:

[base] = [acid]

So, pH=pKa+log1 = pKa

pH is equal to pKa of weak acid of buffer system .

When buffer contains more of weak acid than conjugate base:

[base] < [acid]

log [base]/[acid] = Negative,

So,

When more of acid component is present, the pH is more acidic. (It decreases)

When buffer contains more of conjugate base than weak acid:

[base] > [acid]

log [base]/[acid] = Positive,

So,

When more of acid component is present, the pH is more acidic. (It increases)

Use the van der Waals equation and the ideal gas equation to calculate the pressure for 1.50 mol He gas in a 1.00 L container at

Tamiku [17]

The difference in pressure is 8.98 %.

What is pressure ?

In the physical sciences, pressure is defined as the stress at a point within a confined fluid or the perpendicular force per unit area. A 42-pound box with a bottom area of 84 square inches will impose pressure on a surface equal to the force divided by the area it is applied to, or half a pound per square inch. Atmospheric pressure, which is roughly 15 pounds per square inch at sea level, is the weight of the atmosphere pressing down on each unit area of the Earth's surface. Pascals are used to express pressure in SI units; one pascal is equivalent to one newton per square meter. Almost 100,000 pascals of atmospheric pressure are present.

Two iron oxide samples are given to you where one is red and the other is black. You perform a chemical analysis and you find th

kupik [55]

Answer:

Chemical formula for the black iron oxide sample is FeO

Explanation:

Given:

Mass ratio of black iron oxide sample, Fe/O = 3.491

To determine:

The chemical formula

Calculation:

The mass ratio is Fe:O = 3.491 : 1

Mass of Fe = 3.491 g

Mass of O = 1.000 g

Atomic mass of Fe =55.85 g/mol

Atomic mass of O = 16.00 g/mol

$Moles\ Fe = \frac{3.491g}{55.85g/mol} =0.625\\\\Moles\ O = \frac{1.000g}{16.00g/mol} =0.0625\\$

Therefore, the molar ratio of Fe:O = 1:1

Hence, chemical formula is FeO
