Various pieces of safety equipment are used in the lab to provide protection against injury. However, the lab safety equipment which is least likely to be used when proper eye goggles are being worn is the eye wash station. If this question has the same choices as the ones posted before, the answer is letter C. eye wash station.
Answer:
6 moles of Cl2
Explanation:
First, the equation has to be balanced, which makes it 4 FeCl3 + 3 O2 --> 2 Fe2O3 + 6 Cl2
Using this information, we can see that one mole of O2 will not be present in the reaction. Since four moles of FeCl3 are needed to react in the equation, which would produce six moles of Cl2, and only four moles of FeCl3 are present, six moles of Cl2 would be produced.
Answer:

It is <u>true</u> that ionic compounds are formed from atoms that have opposite charges.
<h3>What are ionic compounds?</h3>
Ionic compounds are chemical compounds made up of ions held together by electrostatic forces termed ionic bonding.
The ionic compound formed is neutrally charged but consists of positively charged ions called cations and negatively charged ions called anions.
For example, the sodium ions attract chloride ions and the chloride ion attracts sodium ions. The result is the formation of an ionic compound with cation Na+ and anion Cl– ions.
Therefore, it is true that an ionic compound is made up of positive and negative ions.
