<span>The option A is correct answer. The isotopes are X and Y. The isotopes are those which have same atomic number but different mass number. Since atomic number has same number of protons or electrons. Thus, isotopes have same number of protons or electrons. Therefore, X and Y are isotopes.</span>

spin [16.1K]

The nurse would want to call a rapid response, place the patient on oxygen, and prepare for the administration of Epinephrine. This drug is the first-line treatment for anaphylactic shock. It will increase blood pressure, decrease swelling, and dilate the airway.

“Nursing is not an easy job. It takes physical and mental stamina to survive a 14-hour shift.” If you believe, you may find yourself thriving. in the midst of activity.

There is much to learn. The exams are difficult, the schedules are complex, and the challenges pile up. All these factors can make life as a student difficult. Nursing is a highly competitive field from the moment you start the application process until you graduate.

Given 6.0 mol of N2 are mixed with 12.0 mol of H2. Equation: N2 + 3H2--&gt; 2NH3
andrey2020 [161]
1) Excess reagent

1 mol N2 / 3 mol H2

6.0 mol N2 *3 mol H2 / 1 mol N2 = 18 mol H2

18mol H2 > 12 mol H2 =>  H2 is limiting (you  need 18 mol H2 to use all the 6 mol N2), then N2 is in excees.

12.0 mol H2 * 1mol N2/ 3 mol H2  = 4 mol N2 is the quantity that will react, then the excess is 6 mol N2 - 4 mol N2 = 2 mol N2

2) NH3 produced

12 mol H2 * [2 mol NH3 / 3 mol H2] = 8 mol NH3

Aslso, 4 mol N2 *[2molNH3 / 1 molN2] = 8 mol NH3, the same result.

3) Yield

80% * 8 mol NH3 = 6.4 mol NH3
