Answer:
A: 92.02 g
Explanation:
Equation of the reaction;
N2 (g)+ 2O2(g)------> 2NO2(g)
Note that the balanced reaction equation is the first step in solving any problem on stoichiometry. Once the reaction equation is correct, the question can be easily solved...
4. If you evaporate the water first, then the sand and salt will be nearly impossible to separate. That eliminates 1 and 2. You can't filter salt out from an aqueous solution, so that eliminates 3. 4 works because you can filter out the sand (which doesn't dissolve) then evaporate the water away from the salt.
For the answer to answer above, <span>O - Ordered structure </span>
<span>H - maintain Homeostasis with the environment </span>
<span>S - respond to Stimuli from the environment </span>
<span>A - Adaptation to the environment </span>
<span>R - ability to Reproduce </span>
<span>G - Grow and develop over the period of their life </span>
<span>E - transform Energy from the environment </span>
<span>Remember, all life is made from cells (this is not a "process" that living things carry out, but rather a property of life itself).</span>
Approximately 71.77 grams. I think so
