Which of the following conditions characterizes a system in a state of chemical equilibrium?
 
  A) Concentrations of reactants and products are equal.
  B) Rate of forward reaction has dropped to zero.
  C) Reactants are being consumed at the same rate they are being produced.
  D) Reactant molecules no longer react with each other.
  E) Product concentrations are greater than reactant concentrations.

Question 2

Sketch a diagram to illustrate the role of orientation in determining whether a collision between molecules of two different diatomic elements will lead to formation of a compound.
 
  How could you illustrate the influence of energy considerations on this reaction?

Answer to Question 1

C

Answer to Question 2

The diagram should show the two diatomic molecules touching each other so that the two pairs of different atoms are in contact. The drawing may also include lines showing that the bonds in the molecules of the elements are broken and new bonds form between the two different elements:

X---X X X
 
O---O O O

To illustrate the importance of energy, a heavy line could be used to indicate how hard the impact between X2 and O2 is, using a darker or wider line for a stronger impact. Part of activation energy involves an impact with sufficient energy.

Hippocrates noted that blood separates into four differently colored liquids when removed from the body and examined: a pure red liquid mixed with white liquid material with a yellow-colored froth at the top and a black substance that settles underneath; he named these the four humors (for blood, phlegm, yellow bile, and black bile).

Pope Sylvester II tried to introduce Arabic numbers into Europe between the years 999 and 1003, but their use did not catch on for a few more centuries, and Roman numerals continued to be the primary number system.

The senior population grows every year. Seniors older than 65 years of age now comprise more than 13% of the total population. However, women outlive men. In the 85-and-over age group, there are only 45 men to every 100 women.

People with alcoholism are at a much greater risk of malnutrition than are other people and usually exhibit low levels of most vitamins (especially folic acid). This is because alcohol often takes the place of 50% of their daily intake of calories, with little nutritional value contained in it.

Did you know?

There used to be a metric calendar, as well as metric clocks. The metric calendar, or "French Republican Calendar" divided the year into 12 months, but each month was divided into three 10-day weeks. Each day had 10 decimal hours. Each hour had 100 decimal minutes. Due to lack of popularity, the metric clocks and calendars were ended in 1795, three years after they had been first marketed.
