If the hydrogen ion concentration of an unknown solution is 4.56E-7, what is its pH and will this form an acid or a base?
Inessa05 [86]

If the hydrogen ion concentration of an unknown solution is 4.56E-7, the pH of the solution will be 6.34 and it will form an acid.

<h3>How to calculate pH from H+?</h3>

The pH, which is the power of hydrogen, can be calculated from the hydrogen ion concentration using the following expression:

pH = - log [H+]

According to this question, the hydrogen ion concentration of an unknown solution is 4.56E-7. The pH is as follows:

pH = - log [4.56E-7]

pH = 6.34

Therefore, If the hydrogen ion concentration of an unknown solution is 4.56E-7, the pH of the solution will be 6.34 and it will form an acid.

Enter the chemical formula of a binary molecular compound of hydrogen and a Group 6A element that can reasonably be expected to
rosijanka [135]

The question is incomplete, the complete question is;

Enter the chemical formula of a binary molecular compound of hydrogen and a Group 6A element that can reasonably be expected to be more acidic in aqueous solution than H2S , e.g. have a larger Ka.

Answer:

H2Se

Explanation:

The acidity and extent of acid dissociation (shown by Ka value) depends on the nature of the bond between hydrogen and the group 6A element.

If we compare the H-S bond and the H-Se bond, we will discover that the H-Se bond is longer, weaker and breaks more easily than the H-S bond. As a result of this, H2Se is more acidic than H2S.

a mixture of emanations from radioactive atoms is passed through electrically charged plates imagination number one is attracted
slava [35]
Hello there!

The nuclear emanations 1, 2 and 3 are called, respectively:

1) Alpha, beta and gamma

Alpha Radiation consists of two protons and two neutrons, as protons are positive particles, they will be attracted to the negatively charged plate.

Beta Radiation 
is composed of a high-energy electron. As electrons are negative particles, they will be attracted to the positively charged plate.  

Gamma Radiation is composed or photons. Photons don't have charge or mass, and they will not be attracted to the charged plates. This kind of radiation is more penetrating than the other two.

Have a nice day!
