A) Increasing temperature increases solubility

The majority of the slopes on the graph are positive, which means it's a direct proportion, so as the temperature increases, so does the solubility.

The answer is A. As the temperature increases, the solubility rate shows exponential growth. This indicates that there is a positive correlation between the two factors, allowing solubility to increase alongside temperature.

Which formula can be used to calculate the molar mass of ammonia
Nikolay [14]

Answer:

Since there are 3 Hydrogen atoms present, the formula mass of H is 1.0 × 3 = 3.0 g/mol. Therefore, by adding them up, the formula mass of ammonia is: [14.0 g/mol + 3.0 g/mol] = 17.0 g/mol.

How to clean a nose piercing with antibacterial soap?.
pychu [463]
Cleaning the nose piercing with a few simple steps will help prevent pre-existing conditions like infections, allergic reactions or skin damage. Performing regular maintenance will keep your piercing cleaner, more comfortable and easier to clean in the future.(Remember: If you have any problems I recommend visiting a doctor at your earliest convenience!) Antibacterial soap is great at reducing inflammation and clearing up infections. You should soak your nose in it regularly and use a clean cloth to gently wash away any particles that may have fallen into the septum.

Which component of a plant makes the cell walls around plant cells tough and allows branches, stems, and leaves to be strong
Vsevolod [243]
<h3><u>Answer;</u></h3>

Cellulose

<h3><u>Explanation</u>;</h3>
  • Cellulose is a polysaccharide and the most abundant organic compound on the Earth's surface.
  • <em><u>It  is an important organic molecule due to its strong structure which provides a wide variety of functions. </u></em>
  • <em><u>Cellulose is a major component of tough cell walls that surround plant cells and is what makes plant stems, leaves, and branches very  strong.</u></em>
  • The molecules of cellulose are arranged such that they are parallel to each other joined by hydrogen bond. this arrangement forms long structures that combine with other cellulose molecules producing a strong support structure.

A 51.24-g sample of Ba(OH)2 is dissolved in enough water to make 1.20 liters of solution. How many mL of this solution must be d
g100num [7]

Answer:

0.40 L

Explanation:

Calculation of the moles of Ba(OH)_2 as:-

Mass = 51.24 g

Molar mass of Ba(OH)_2 = 171.34 g/mol

The formula for the calculation of moles is shown below:

moles = \frac{Mass\ taken}{Molar\ mass}

Thus,

Moles= \frac{51.24\ g}{171.34\ g/mol}

Moles= 0.2991\ mol

Volume = 1.20 L

The expression for the molarity is:

Molarity=\frac{Moles\ of\ solute}{Volume\ of\ the\ solution}

Molarity=\frac{0.2991\ mol}{1.20\ L}=0.24925\ M

Thus,

Considering

Molarity_{working\ solution}\times Volume_{working\ solution}=Molarity_{stock\ solution}\times Volume_{stock\ solution}

Given  that:

Molarity_{working\ solution}=0.100\ M

Volume_{working\ solution}=1\ L

Volume_{stock\ solution}=?

Molarity_{stock\ solution}=0.24925\ M

So,  

0.100\ M\times 1\ L=0.24925\ M\times Volume_{stock\ solution}

Volume_{stock\ solution}=\frac{0.100\times 1}{0.24925}\ L=0.40\ L

<u>The volume of 0.24925M stock solution added = 0.40 L </u>
