Hello, Brainly User!

As the planet gets warmer, sea level rises for two reasons. First, warmer temperatures cause ice on land like glaciers and ice sheets to melt, and the melt water flows into the ocean to increase sea level. Second, warm water expands and takes up more space than colder water, increasing the volume of water in the sea.

Hope this helps, i was super glad and exited to help you out with this question! Have a great day..

Consider a 125 mL buffer solution at 25°C that contains 0.500 mol of hypochlorous acid (HOCl) and 0.500 mol of sodium hypochlori

Helga [31]

Answer:

pH = 6.82

Explanation:

To solve this problem we can use the Henderson-Hasselbach equation:

pH = pKa + log $\frac{[NaOCl]}{[HOCl]}$

We're given all the required data to calculate the original pH of the buffer before 0.341 mol of HCl are added:

pKa = -log(Ka) = -log(2.9x10⁻⁸) = 7.54

[HOCl] = [NaOCl] = 0.500 mol / 0.125 L = 4 M

pH = 7.54 + log $\frac{4}{4}$

pH = 7.54

By adding HCl, we simultaneously increase the number of HOCl and decrease NaOCl:

pH = 7.54 + log $\frac{[NaOCl-HCl]}{[HOCl+HCl]}$

pH = 7.54 + log $\frac{(0.500mol-0.341mol)/0.125L}{(0.500mol+0.341mol)/0.125L}$

pH = 6.82

250 ml glass of lemon juice contains 20 grams of sugar. How much sugar is in 500 ml bottle

iren2701 [21]

There is 40 g of sugar in a 500 ml bottle of lemon juice

<h3>Further explanation</h3>

The concentration of a substance can be expressed in several quantities such as moles, percent (%) weight/volume,), molarity, molality, parts per million (ppm) or mole fraction. The concentration shows the amount of solute in a unit of the amount of solvent.

the concentration of sugar in lemon juice :

$\tt \dfrac{20~g}{250~ml}=0.08~g/ml$

So for 500 ml juice :

$\tt 500\times 0.08=40~g~sugar$
