The sugar is called solute and water is called solvent. And the sugar and water together is called solution.
Answer:
false
true
true
Explanation:
false - changing the hypothesis to meet your needs is not a good researcher
true - when you can further analyze and explain then you have a successful experiment even if it's not what you expected
true - successful experiments do not end there. they can lead to more in depth questions.
Answer:
a. Oxygen is the limiting reagent.
b. %
Explanation:
Hello,
a. Limiting reagent and sulfur trioxide's theoretical yield.
At first, we must compute the involved moles for both sulfur dioxide's and oxygen's as follows, considering the volumes in liters and the pressure in atm of 50.0mmHg*1atm/760mmHg=0.0658atm:
Afterwards, by considering the properly balanced chemical reaction:
We compute the oxygen's moles that completely reacts with the previously computed moles of as follows:
That result let us know that the oxygen is the limiting reagent since just moles are available in comparison with the moles that completely would react with moles of .
Now, to compute the theoretical yield of sulfur trioxide, we apply the following stoichiometric relationship:
b. Percent yield.
At first, we must compute the collected (real) moles of sulfur trioxide:
Finally, we compute the percent yield:
%
%
%
