2Fe(s) + 3Cl₂(g) →2FeCl₃(s)

mol Fe = 15.52 : 56 g/mol = 0.277

mol FeCl₃ = mol Fe = 0.277 (same coefficient)

mass FeCl₃ = 0.277 x 162.2 g/mol = 44.93 g

% yield = 34.5 : 44.93 = 76.79 %

A chemist is using a solution of HNO3 that has a pH of 3. 75. What is [H ] for the solution? Round to the nearest hundredth. × 1
Alexeev081 [22]

The estimation of the acidic and the basic character of a solution is called and defined by the pH. The \rm [H^{+}] concentration of the solution will be \rm 1.77\times 10^{-4}.

<h3>What is the pH?</h3>

pH is a measurement of the free hydrogen and hydroxyl ions in the solution of the substance.

It can be calculated as:

\rm pH  = - \rm log[H^{+}]

Given,

pH = 3.75

Substituting values in the equation:

\begin{aligned}\rm 3.75 &= -\rm log[H^{+}]\\\\\rm [H^{+}] &= 10^{-3.75}\\\\&= 1.7782 \times 10^{-4}\end{aligned}

Therefore,  \rm 1.77\times 10^{-4} is the concentration of the hydrogen ions.

Serggg [28]

Answer:

The octet rule means that atoms need a total of 8 valence electrons to fill their valence shell. Hydrogen only needs two to fill its valence shell.

Explanation:

All atoms except for hydrogen can hold a total of 8 valence electrons in their outer energy levels (2 in the s level, 6 in the p level). Hydrogen only has two electrons total, so it does not require more than the s level and two electrons to have a full valence.
