Answer:
NaOH is the limiting reactant.
Explanation:
Hello there!
In this case, since the reaction taking place between sodium hydroxide and chlorine has is:
![NaOH+Cl_2\rightarrow NaCl+NaClO+H_2O](https://tex.z-dn.net/?f=NaOH%2BCl_2%5Crightarrow%20NaCl%2BNaClO%2BH_2O)
Which must be balanced according to the law of conservation of mass:
![2NaOH+Cl_2\rightarrow NaCl+NaClO+H_2O](https://tex.z-dn.net/?f=2NaOH%2BCl_2%5Crightarrow%20NaCl%2BNaClO%2BH_2O)
Whereas there is a 2:1 mole ratio of NaOH to Cl2, which means that the moles of the former that are consumed by 0.85 moles of the latter are:
![n_{NaOH}=0.85molCl_2*\frac{2molNaOH}{1molCl_2}\\\\n_{ NaOH}=1.7molNaOH](https://tex.z-dn.net/?f=n_%7BNaOH%7D%3D0.85molCl_2%2A%5Cfrac%7B2molNaOH%7D%7B1molCl_2%7D%5C%5C%5C%5Cn_%7B%20NaOH%7D%3D1.7molNaOH)
Therefore, since we just have 1.23 moles out of 1.70 moles of NaOH, we infer this is the limiting reactant.

Answer: One formula unit of NaCl consists of one cation, whose chemical symbol is
and one anion whose chemical symbol is ![Cl^-](https://tex.z-dn.net/?f=Cl%5E-)
Explanation:
For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
The cation is formed by the metal sodium which forms
and the anion is formed by non metal chlorine which forms
.
For a formula unit of sodium chloride, the charges have to be balanced , thus the valencies of ions are exchanged and the neutral compound result. Thus
and
combine to form neutral ![NaCl](https://tex.z-dn.net/?f=NaCl)
Answer:
There are many properties that differentiate metals from non-metals. They are: Luster, conductivity of heat and electricity, physical strength i.e. Brittle or difficult to break, etc.
