The chemical reaction for this is expressed as:
<span> 4FeCO3 + 4O2 ----> 4FeO3 + 4CO2
</span>
We are first need to calculate the theoretical amount of ferric oxide that whould be obtain from the given amount of ore. We do as follows:

75 g FeCO3 ( 1 mol / <span>116 g ) ( 4 mol FeO3 / 4 mol FeCO3 ) ( 103.84 g / mol ) = 67.14 g FeO3 theoretically produced
</span>
Percent yield = actual mass / theoretical mass x 100 = 45 / 67.14 x 100 = 67.03%

almond37 [142]

Answer:

D

Explanation:

The formula for calculating kinetic energy is 1/2mv^2, where m is the mass and v is the velocity or speed of the object. Since all of the balls have the same mass, the one with the highest speed or velocity will have the highest kinetic energy. Hope this helps!
