Calculate the pH of a solution that has [H30*] = 5.2 x 10-7M

Chemistry

Answer:

pH ≈ 6.3

Explanation:

To calculate the pH of an aqueous solution, you need to know the hydronium ion (H₃O+) concentration in moles per liter (molarity).  The pH is then calculated using the expression:

      pH = - log [H₃O+]

Since the solution has an H₃O+ ion concentration of 5.2 × 10⁻⁷ M, we can plug that in and solve:

      pH = - log [5.2 × 10⁻⁷]

      pH = 6.28

Flow of heat energy through liquids and<br> gases
riadik2000 [5.3K]
Answer : I hope this helps !

Liquids and gases are fluids because they can be made to flow. The particles in these fluids can move from place to place. Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy.

The elements C and Se have the same electronegativity value, 2.55. Which of the following claims about the compound that forms f
Rom4ik [11]

Answer:

B

Explanation:

Having the same electronegativity means that the both elements will form a nonpolar bond. The shared electrons of the bind will be found equidistant from the nucleus of the two atoms because none has an unusual ability to attract the electrons of a bond towards itself.

A chemist prepares a solution of silver(I) nitrate by measuring out of silver(I) nitrate into a volumetric flask and filling the
leva [86]

Answer:

3.33 M

Explanation:

It seems your question is incomplete, however, that same fragment has been found somewhere else in the web:

" <em>A chemist prepares a solution of silver nitrate (AgNO3) by measuring out 85.g of silver nitrate into a 150.mL volumetric flask and filling the flask to the mark with water.</em>

<em>Calculate the concentration in mol/L of the chemist's silver nitrate solution. Be sure your answer has the correct number of significant digits.</em> "

In this case, first we <u>calculate the moles of AgNO₃</u>, using its molecular weight:

  • 85.0 g AgNO₃ ÷ 169.87 g/mol = 0.500 mol AgNO₃

Then we<u> convert the 150 mL of the volumetric flask into L</u>:

  • 150 / 1000 = 0.150 L

Finally we <u>divide the moles by the volume</u>:

  • 0.500 mol AgNO₃ / 0.150 L = 3.33 M

How is heat produced in a chemical change​
Snezhnost [94]

Answer:Hola UwU

Most chemical reactions involve the breaking and formation of chemical bonds. It takes energy to break a chemical bond but energy is released when chemical bonds are formed. If more energy is released than consumed, then the chemical reaction evolves heat and is said to be exothermic.

Explanation:Adios~ UnU haha
