Answer:
4.86moles of barium sulfide are produced
Explanation:
To solve this question we need to convert the mass of barium sulfide (BaS) to moles using the molar mass of BaS:
<em>Molar mass BaS:</em>
<em>1 Ba atom = 137.3g/mol</em>
<em>1 S atom = 32.1g/mol</em>
<em>Molar mass BaS = 137.3 + 32.1 = 169.4g/mol</em>
<em />
<em>Moles in 823g of BaS:</em>
823g * (1mol / 169.4g) =
<h3>4.86moles of barium sulfide are produced</h3>
It is Scandium or Sc
