Answer:
The molar mass and molecular weight of Sn(CO3)2 is 238.728.
Explanation:
There are two naturally occurring isotopes of gallium: mass of Ga-69 isotope is 68.9256 amu and its percentage abundance is 60.11%, let the mass of other isotope that is Ga-71 be X, the percentage abundance can be calculated as:
%Ga-71=100-60.11=39.89%
Atomic mass of an element is calculated by taking sum of atomic masses of its isotopes multiplied by their percentage abundance.
Thus, in this case:
Atomic mass= m(Ga-69)×%(Ga-69)+X×%(Ga-71)
From the periodic table, atomic mass of Ga is 69.723 amu.
Putting the values,

Thus,

Rearranging,

Therefore, mass of Ga-71 isotope is 70.9246 amu.
It is, Reactants react to produce new substances known as products.
because a chemical reaction is the combining of different reactants
Answer:
Explanation:
The chemical reaction of the well-balanced equation is as follows:

The aforementioned reaction's ionic equation is:

From above; Na⁺ and Cl⁻ appear on both sides;
Hence, the net ionic equation is:
