Solution Steps

Step 1: Analyze the Given Reaction

The given chemical reaction is:

\[ 2 \mathrm{H}_{2} \mathrm{O}(\mathrm{l}) \rightarrow 2 \mathrm{H}_{2}(\mathrm{~g})+\mathrm{O}_{2}(\mathrm{~g}) \]

This reaction involves the breakdown of water (\(\mathrm{H}_{2}\mathrm{O}\)) into hydrogen gas (\(\mathrm{H}_{2}\)) and oxygen gas (\(\mathrm{O}_{2}\)).

Step 2: Identify the Reaction Type

To identify the reaction type, we need to understand the nature of the transformation:

  • Single-displacement reaction: Involves an element displacing another in a compound.
  • Double-displacement reaction: Involves the exchange of ions between two compounds.
  • Decomposition reaction: A single compound breaks down into two or more simpler substances.
  • Synthesis reaction: Two or more simple substances combine to form a more complex compound.

In this case, a single compound (\(\mathrm{H}_{2}\mathrm{O}\)) is breaking down into two simpler substances (\(\mathrm{H}_{2}\) and \(\mathrm{O}_{2}\)).

Final Answer

The reaction type is a decomposition reaction.

\[ \boxed{\text{decomposition}} \]

1920s and 1930s, Hawthorne Works was the site of some well-known industrial studies. In one of the studies, researchers investigated the impact of different working conditions on worker productivity. Prior to the start of the study, researchers secretly measured workers' productivity for several weeks. Then researchers chose two workers, who then chose their own teams. The teams were separated from the general workforce and completed their work in different experiment rooms where the researchers could observe them more easily. Over a 5-year period researchers manipulated the structure of the workday for each team (number and duration of breaks and number of hours per shift). For each of these changes in working conditions, the researchers measured the effect on productivity. For some conditions, such as frequent short breaks, workers rebelled by intentionally decreasing productivity. Why did the researchers secretly measure the workers' productivity before creating the two treatment groups? To create similar treatment groups so that a cause-and-effect relationship could be established To provide a baseline for measuring worker productivity To directly control for confounding variables
