The reaction between boron sulfide and carbon is given as:
2B2S3 + 3C → 4B + 3CS2
As per the law of conservation of mass, for any chemical reaction the total mass of reactants must be equal to the total mass of the products.
Given data:
Mass of C = 2.1 * 10^ 4 g
Mass of B = 3.11*10^4 g
Mass of CS2 = 1.47*10^5
Mass of B2S3 = ?
Now based on the law of conservation of mass:
Mass of B2S3 + mass C = mass of B + mass of CS2
Mass of B2S3 + 2.1 * 10^ 4 = 3.11*10^4 + 1.47*10^5
Mass of B2S3 = 15.7 * 10^4 g
excess hydrogen ions can break chemical bonds
, can change the shape of large complex molecules, rendering them nonfunctional and can disrupt tissue function.
Answer:
Iron‑56 is the most abundant isotope, so the atomic mass of iron is most similar to the mass of iron‑56.
Explanation:
The atomic abundance of the isotopes of Iron is:
⁵⁴Fe: 5.82%
⁵⁶Fe: 91.66%
⁵⁷Fe: 2.19%
⁵⁸Fe: 0.33%
<em>Where the Iron-56 is the most abundant isotope of Iron atom</em>
<em />
As atomic mass is defined as the sum of the masses of the ions multiplied by its abundance, and the Iron-56 is the most abundance isotope, the atomic mass of Fe most be similar to the ⁵⁶Fe mass because is the most abundant isotope.
Right option is:
<h3>Iron‑56 is the most abundant isotope, so the atomic mass of iron is most similar to the mass of iron‑56.</h3>
