Why are state symbols used in chemical equations?

Chemistry
1 answer:
Zolol [24]3 years ago
3 0

Answer:

Explanation:

The state symbols been referred to in the question are <em>s,l,aq </em>and <em>g. </em>

<em>s </em>stands for solid

<em>l </em>stands for liquid

<em>aq </em>stands for aqueous

<em>g </em>stands for gas

The major reason this symbols are used is to signify the state of the molecules involved in the reaction. This is because the state of a substance  sometimes shows the type of a product that will be formed and some other times, a substance in a particular state might have a certain property (required  for a reaction) and in some other state would not have the same property. Hence it helps in understanding a reaction better. The following example should assist in understanding better

ZnS04(aq) + Cu(s) → CuSO4(aq) + Zn(s)

The reaction above shows ZnSO4 to be aqueous in the reactant but ZnSO4 could also be solid, however, for this reaction to occur, the compound must be in it's aqueous form. This product been solid zinc also shows that the reaction is an electrolytic equation as zinc (Zn) has been displaced by copper (Cu) from the solution. This reaction will typically not proceed also if the ZnSO4 used is solid.

The average atomic mass of the imaginary element : 47.255 amu

<h3>Further explanation  </h3>

The elements in nature have several types of isotopes  

Isotopes are elements that have the same Atomic Number (Proton)  

Atomic mass is the average atomic mass of all its isotopes  

Mass atom X = mass isotope 1 . % + mass isotope 2.% ..

isotope E-47 47.011 amu, 87.34%

isotope E-48 48.008 amu, 6.895

isotope E-49 50.009 amu, 5.77%

The average atomic mass :

\tt avg~mass=0.8734\times 47.011+0.06895\times 48.008+0.0577\times 50.009\\\\avg~mass=41.059+3.310+2.886\\\\avg~mass=47.255~amu

Iodine monochloride (ICl) has a higher boiling point than bromine (Br2) partly because iodine monochloride is a(n)
tekilochka [14]

Answer: polar molecule.

Explanation:

The boiling point is the temperature at which the vapor pressure of a liquid equals the external pressure surrounding the liquid. The boiling point is dependent on the type of forces present.

Iodine monochloride (ICl) is a polar molecule due to the difference in electronegativities of iodine and chlorine. Thus the molecules are bonded by strong dipole dipole forces. Thus a higher temperature is needed to generate enough vapor pressure.

Bromine (Br_2) is a non polar molecule as there is no electronegativity difference between two bromine atoms. The molecules are bonded by weak vanderwaal forces and thus has low boiling point.
