<span>1) Balanced chemical equation

Sb2S3(s) + 3Fe(s) --> 2Sb(s) + 3FeS(s)

2) Theoretical molar ratios

1 mol SbsS3 : 3 mol Fe : 2 mol Sb : 3 mol FeS

3) Convert </span><span>18.45g Sb2S3 and12.1g Sb to moles

You need to use the atomic and molar masses

Sb: 121.76 g/mol

S: 32.07 g/mol

Sb2S3: 2 * 121.76 g/mol + 3 * 32.07 g/mol = 339.73 g/mol

18.45 g Sb2S3 / 339.73 g/mol = 0.0543 mol Sb2S3

12.1 g Sb / 121.76 g / mol = 0.099 mol Sb

Theoretical yield:

1 mol Sb2S3 / 2 mol Sb = 0.0543 mol SbsS3 / x mol Sb

Solve for x:

x = 0.0543 mol Sb2S3 * 2 mol Sb / 1 mol Sb2S3 = 0.1086 mol Sb

4) Percent yield

0.099 mol Sb / 0.1086 mol Sb * 100 = 91.16%

Answer: 91.5% (the difference with 91.16% is due to the decimals used for the atomic masses)

Why is an atom regarded as electrically unstable​
meriva

Answer: An atom can be considered unstable in one of two ways. If it picks up or loses an electron, it becomes electrically charged and highly reactive. Such electrically charged atoms are known as ions. Instability can also occur in the nucleus when the number of protons and neutrons is unbalanced.
