It is important for scientists to have a standard system of naming compounds and other chemical procedures to avoid ambiguity in the nomenclature of chemical compounds and procedures.
Chemicals may be referred to by various names among various scientists in different places. These different names creates confusion when scientists present their discoveries to other scientists outside their locality.
Therefore, it is imperative that a unified and standard system of nomenclature should be devised so that all scientists can have the same name for compounds. This reduces ambiguity associated with the nomenclature of chemical substances and procedure.

Answer:
3,924°F
Explanation:
here is the answer it is a little hard to explain but hopeing it helps you a lot
The volume of ethyl alcohol overflow will be 9.265mL.
To calculate the volume of ethyl alcohol overflow, we will use
∆V=V(á∆T)
Where,
∆V=volume expand
á=volumetric expansion Coefficients =0.00109/°C
V=initial volume =500ml
T'=final temp. =22°C
T=initial temp=5°C
Now,
∆V=500×(0.00109/°C) ×(22-5)
=500×(0.00109) (17)
=9.265ml
Thus, we find that the volume of ethyl alcohol overflow will be 9.265 mL.

Answer:
Net ionic equation: 2I⁻(aq) + Cr²⁺(aq) → CrI₂(s)
<h3>
Explanation:</h3>
- A chemical equation shows chemical symbols of compounds known as reactants and compounds known as products in a chemical reaction.
- The chemical equation between hydroiodic acid and chromium (II) carbonate is given by;
2HI(aq) + CrCO₃(aq) → H₂CO₃(aq) + CrI₂(s)
- The Ionic equation is an equation that shows all the ions involved in a chemical reaction.
- In this case, the ionic equation is;
2H⁺ I⁻(aq)+ Cr²⁺ CO₃²⁻(aq) → 2H⁺ CO₃²⁻(aq) + CrI₂(s)
- The net ionic equation is an equation showing only the ions that take part in the reactions. The ions that do not take part in the chemical reaction known as spectator ions are not shown when writing net ionic equations.
- Spectator ions are those ions that do not change state after the chemical reaction has taken place. In this case, hydrogen ions and carbonate ions are spectator ions.
- The net ionic equation is
2I⁻(aq) + Cr²⁺(aq) → CrI₂(s)
