A student needs to prepare a stock solution for the lab - 500.0 ml of 0.750 m nitric acid. The student is provided with concentr
dlinn [17]

Molarity of concentrated nitric acid = 15.9 M

Volume of the stock solution to be prepared = 500.0 mL

Concentration of the stock that is to be prepared = 0.750 M

Calculating moles from molarity and volume of stock:

500.0mL*\frac{1L}{1000mL}*0.750\frac{mol}{L}  =0.375 mol HNO_{3}

Calculating volume of concentrated nitric acid to be taken for the preparation of stock solution:

0.375mol*\frac{1L}{15.9mol} =0.0236 L

Converting L to mL:

0.0236L*\frac{1000mL}{1L} = 23.6 mL

Volume of distilled water to be added to 23.6 mL of 15.9 M nitric acid to get the given concentration = 5000.0mL-23.6mL=976.4 mL

Therefore, 976.4 mL distilled water is to be added to 23.6 mL of 15.9 M nitric acid solution to prepare 500.0 mL of 0.750M nitric acid.

Help please! What is the mass of the iron (Fe) involved in this reaction? Identify the following equations as balanced or unbala
eimsori [14]
<h2>Question 1:</h2><h3>32g + <u><em>56g</em></u> --> 88g</h3>

This one's just a simple math problem. Do 88 - 32, which is 56. You can also find the same answer by looking for the atomic mass of iron (Fe), which rounds up to 56.


<h2>Question 2:</h2><h3>This equation is <u><em>balanced</em></u>.</h3>

On the left side, there is 2 Nitrogen (because of the subscript), and 6 Hydrogen (3 x 2 = 6). On the right side, there is 2 Nitrogen (because of the coefficient), and 6 Hydrogen. (2 x 3 again) There are 2 Nitrogen and 6 Hydrogen on each side, therefore the equation is balanced.


<h2>Question 3:</h2><h3>This equation is <em><u>unbalanced.</u></em></h3>

On the left side, there are 2 Nitrogen (N) and 2 Hydrogen (H). On the right side, there is 1 Nitrogen and 6 Hydrogen. There are 2 Nitrogen and 2 Hydrogen on one side, while the other only has 1 Nitrogen and 6 Hydrogen. Therefore the equation is unbalanced.


<h2>Question 4:</h2><h3>This equation is <em><u>balanced.</u></em></h3>

On the left side, there are 2 Chromium (Cr) and 6 Chlorine (Cl). On the right side, there are 2 Chromium and 6 Chlorine. There are 2 Chromium and 6 Chlorine on each side, therefore the equation in balanced.
