Answer:
Percent yield = 7.1%
Explanation:
The general reaction of the problem is:
Ca(OH)₂ + CO₂ → H₂O + CaCO₃
To solve this question we need to find theoretical yield using the amount of carbon dioxide added because:
Percent yield = Actual yield (3.22g) / Theoretical yield * 100
Theoretical yield is the maximum amount of product that could be obtained. To find it we need to convert the mass of CO₂ to moles. The moles of CO₂ = Moles of CaCO₃:
<em>Moles CO₂ -Molar mass: 44.01g/mol):</em>
20.0g * (1mol / 44.01g) = 0.454 moles CO₂ = Moles of CaCO₃ produced
<em>Mass CaCO₃ = Theoretical yield -Molar mass: 100.09g/mol-:</em>
0.454 moles * (100.09g / mol) = 45.5g of CaCO₃ = Theoretical yield.
Replacing:
Percent yield = 3.22g / 45.5g * 100
<h3>Percent yield = 7.1%</h3>
Solid: The particles (i.e. atoms or compounds) vibrate about their fixed positions and are relatively very close to each other.
Liquid: The particles move about relatively VERY SHORT distances and move freely, flowing around other particles at high speeds.
Gas: The particles move far from each other about relatively very great distances at high speeds.
The sedimentary rock formed when water deposits tiny particles of clay in very thin flat layers is called limestone.
Answer:
I think the answer would be the arrangment of the mineral's atoms.
Explanation:
that is how it gets physical and chemical properties.
