Answer:
19.5g is the theoretical yield of alum
Explanation:
Based on the balanced reaction, 4 moles of sulfuric acid produce 2 moles of alum. To solve this question we need to find the moles of H2SO4. With these moles we can find the moles of alum and its mass assuming all sulfuric acid reacts producing alum.
<em>Moles Sulfuric Acid:</em>
8.3mL = 0.0083L * (9.9mol/L) = 0.08217 moles sulfuric acid
<em>Moles Alum:</em>
0.08217 moles sulfuric acid * (2mol KAl(SO4)2•12H2O / 4mol H2SO4) =
0.041085 moles KAl(SO4)2•12H2O
<em>Mass Alum -Molar mass: 474.3884 g/mol-</em>
0.041085 moles KAl(SO4)2•12H2O * (474.3884 g/mol) =
<h3>19.5g is the theoretical yield of alum</h3>
The answer would be water :)
Answer:
Explanation:
The <em>nuclide isotope notation</em> represents the isotope by its chemical symbol preceded by a superscript (to the left of the chemical symbol) showing the mass number and a subscript (also the the left of the chemical symbol) showing the atomic number (number of protons).
<em>Copper-70:</em>
- Chemical symbol: Cu
- Mass number: 70
- Atomic number: 29 (the atomic number is found in any periodic table)
<em>Nuclide notation</em>:
