Answer:
Filtration (The process of separating liquids and solids)
Explanation:
Filtration works best when the solute isn't dissolved in the solvent. Basically like how you can filter dirt or sand from water. The opposite of this would be if water and sugar where mixed together you cannot unmix this duo with filtration but with the example given you can use the process of filtration to rid the gasoline of sand.
The answer is, C: both Erin and Chris are correct.
<span>(a) Assuming the amount of O2(g) is not limiting the reaction, a mass of 4.23g of Ca(s) will produce an equal mass of CaO(s), hence it will produce 4.23g of CaO(s).
According to their respective molar masses, we have the following CaO molar mass :
Molar mass of Ca + Molar mass of O = 40.1 + 16 = 56.1 g/mol
4.23g of Ca will then produce : 4.23 / 56.1 = 0,07540107 mol of CaO.
(b) With the same reasonment as above, and assuming the amount of Ca is not limiting, we have :
2.87g of O2 will produce : 2.87 / 56.1 = 0,051158645 mol of CaO.
(c) From (a) and (b) answers, we can conclude that the reactant that produces less mol of CaO is limiting the reaction. Hence following the given masses, O2 is the limiting reactant.
(d) Knowing the molar mass of CaO is 56.1 g/mol and knowing that O2 is the limiting reactant, we also know the reaction can produce a maximum of 0,051158645 mol of CaO can be produced.
So we can conclude we will produce :
56.1 * 0,051158645 = 2.87g of CaO.</span>
