Solution Steps

Step 1: Write the balanced chemical equation

The given reaction is: \[ 3 \mathrm{Na}_{2} \mathrm{~S}(a q) + 2 \mathrm{FeCl}_{3}(a q) \longrightarrow \]

Step 2: Identify the products of the reaction

When sodium sulfide (\(\mathrm{Na}_2\mathrm{S}\)) reacts with iron(III) chloride (\(\mathrm{FeCl}_3\)), the products are sodium chloride (\(\mathrm{NaCl}\)) and iron(III) sulfide (\(\mathrm{Fe}_2\mathrm{S}_3\)).

Step 3: Write the complete balanced equation

The balanced chemical equation for the reaction is: \[ 3 \mathrm{Na}_{2} \mathrm{~S}(a q) + 2 \mathrm{FeCl}_{3}(a q) \longrightarrow 6 \mathrm{NaCl}(a q) + \mathrm{Fe}_{2}\mathrm{S}_{3}(s) \]

Step 4: Identify the precipitate

In the reaction, \(\mathrm{Fe}_{2}\mathrm{S}_{3}\) is the solid precipitate that forms.

Final Answer

\(\boxed{\mathrm{Fe}_{2}\mathrm{S}_{3}}\)

In April 2014, Japan's Labor Ministry created a program that offered small- and mid-size Japanese companies a financial reward if they promoted female employees into managerial positions. The Japanese government projected that 400 companies would take advantage of the program which would award payments of up to 300,000 yen (approximately 3,500). Unfortunately, 17 months after the program's inception not one single company had applied for the reward. The ministry admitted that the requirements for receiving the reward may have been too difficult. In an effort to make the program work, the Japanese government lessened the criteria for obtaining the reward, streamlined the application process, and doubled the potential reward amount. In thinking of the diversity challenges that managers face globally, which of the following could explain why the Labor Ministry's program failed? Check all that apply. - There is a smaller percentage of Japanese males in the workforce than females - Japan still practices lifetime employment and age-based promotion - The percentage of women in leadership or managerial roles in Japan is already high - Over 60 percent of Japanese women leave work after their first child is born, often to avoid maternity harassment at work
