Answer:
<h3>option D</h3>
Explanation:
<h3>Is wire A connected to the light bulb </h3>
<h3>because it is series connection</h3>
The answer is A. 1350
(ALL NUMBERS Except the grams is given from the equation)
18.21mol HNO3/1 * 1mol MgN206/2mol/ 2mol HNO3 * (molar mass-->)148.30 MgN206/ 1mol MgN2O6
You multiply 18.21HNO3* 1mol MgN2O6 * 148.30MgN2O6
Then divide it by the 2mol HNO3 to get 1350
The simplest formula for a compound made from element x which is molar mass is equals to 79.0 g/mol that is 21% nitrogen by mass is X sub 2 N sub 3. In addition, X is equals to 79.0 and N is equals to 14.
