What occurs when kcl(s is added to water?
Mama L [17]
When KCL, which is an ionic compound is added to water it will dissociate and or ionize completely forming the ions of K+ and Cl-.

If I need 2.2 moles of CO2 , and I have excess Fe2O3 , how many moles of C do I need?
olchik [2.2K]

Answer:

0.733 mol.

Explanation:

  • From the balanced equation:

<em>2Fe₂O₃ + C → Fe + 3CO₂,</em>

It is clear that 1.0 moles of Fe₂O₃  react with 1.0 mole of C to produce 1.0 mole of Fe and 3.0 moles of CO₂.

  • Since Fe₂O₃ is in excess, C will be the limiting reactant.

<u><em>Using cross multiplication:</em></u>

1.0 mole of C produces → 3.0 moles of CO₂, from the stichiometry.

??? mole of C produces → 2.2 moles of CO₂.

∴ The no. of moles of C needed to produce 2.2 moles of CO₂ = (1.0 mole of C) (2.2 mole of CO₂) / (3.0 mole of CO₂) = 0.733 mol.

Aloiza [94]
The given above pretty much states already that with the presence of the calcium carbonate which acts as the buffer will allow the solution to withstand changes in acidity. The greater the amount, the higher chances that it will be able to withstand the said changes. Therefore, if Lake X had greater ppm of CaCO3 then, it will be able to withstand greater amount of acid rain.

xz_007 [3.2K]

Michigan v. Tyler was the Supreme court ruling that they violated when

warrantless search was done.

<h3>Michigan v. Tyler case</h3>

The Court of Appeals of the State of Michigan affirmed the conviction for the

exception of a warrantless search only in the case of an arson.

In this case, there was no arson involved which is against the rule of law as

various items (stolen money, illegal weapons, drugs) were only searched for.

This thereby violates the U.S. Supreme Court ruling between Michigan v.

Tyler.
