Density = mass / volume
mass of <span>nitroglycerin  = density x volume = 1.592 x 2.5 = 3.98 grams
molar mass of </span>nitroglycerin = 3(12) + 5(1) + 3(14) + 9(16) = 227 grams
<span>number of moles reacting = mass / molar mass = 3.98/227 = 0.017 moles

The balanced chemical equation for this reaction is as follows:
</span>4C3H5N3O9 ..............> 12CO2(g) + 6N2(g) + O2(g) + 10H2O(g)

From the balanced equation:
4 moles of nitroglycerin produces a total of 12 + 6 + 1 + 10 = 29 moles of gas.
Therefore:
0.017 moles of <span>nitroglycerin produces a total of:
(0.017 x 29) / 4 = 0.12325 moles of gases</span>

Below is a bar graph on candy allowance compared to the child's happiness.
rjkz [21]

Answer:

There is no bar graph attached to this question, however, the question can be answered based on the information given in the question.

The answer is A) average level of happiness

Explanation:

In an experiment, the dependent variable is the variable which is measured by the experimenter. It is the variable that responds to changes made to another variable called independent variable.

In the case of this question, it can be determined, even without the bar graph, that the experiment entails how candy allowance affects a child's happiness. Hence, the candy allowance is changed to influence or cause a response in the child's happiness, which is then measured. Therefore, the AVERAGE LEVEL OF HAPPINESS is the dependent variable.
