Scientists observe the world around them, from which to draw questions. Their predictions as to the answer are what we call a “hypothesis”. Thus, a scientist’s job is to answer the very hypotheses that they and their piers come up with.

Answer:

The correct answer will be option-A.

Explanation:

Science is a branch of knowledge which explains the natural phenomenon or process of our surrounding nature.  The branch tries to answer the scientific questions after the logical and sequential steps of the scientific methods are followed.  

In a scientific method, to answer a scientific question, the scientific hypothesis is constructed which could be proved on the basis of experiments based on which results could be concluded.

Thus, scientist performs experiments to understand and answer the hypothesis, therefore, option-A is correct.

If 97.3 L of NO2 forms measured at 35 C and 632 mm Hg. What is the percent yield?
enyata [817]
<span>a. Use PV = nRT and solve for n = number of mols O2. 
mols NO = grams/molar mass = ? 

 Using the coefficients in the balanced equation, convert mols O2 to mols NO2. Do the same for mols NO to mols NO2. It is likely that the two values will not be the same which means one is wrong; the correct value in LR (limiting reagent) problems is ALWAYS the smaller value and the reagent producing that value is the LR. 

b. 
Using the smaller value for mols NO2 from part a, substitute for n in PV = nRT, use the conditions listed in part b, and solve for V in liters. This will give you the theoretical yield (YY)in liters. The actual yield at these same conditions (AY) is 84.8 L. 

</span>and % will be 60%.
