Likurg_2 [28]2 years ago
3 0

Answer:

D

Explanation:

Recall that entropy measures the number of microstates in a substance, which is highest in gases, followed by liquids and solids. Hence, entropy increases if the products have more gaseous molecules than the reactants.

  • In reaction one, chlorine gas is converted into solid NaCl, so entropy decreaes.
  • In reaction two, four moles of gas are converted into two moles of gas, so entropy decreases.
  • In reaction three, ice is melted to form water, which has higher entropy. Thus, entropy increases.
  • In reaction four, a liquid is freezed into its solid phase, leading to a decrease in entropy.
  • In reaction five, oxygen gas is converted into solid MgO, so entropy decreases.

In conclusion, the answer is D.

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.
