Find the limiting reagent if 0.25 moles of Co2 react with 0.1 moles of KO2​
brilliants [131]

Answer:

KO₂ is limiting reactant

Explanation:

Based on the balanced reaction:

2CO₂ + 4KO₂ → 2K₂CO₃ + 3O₂

<em>2 moles of CO₂ react with 4 moles of KO₂.</em>

<em />

Thus, for a complete reacction of 0.25 moles of CO₂ are required:

0.25 moles * (4moles KO₂ / 2moles CO₂) = 0.5 moles of KO₂

As there are just 0.1 moles:

<h3>KO₂ is limiting reactant</h3>

How do you know when a solution is saturated? _____________________________________________________ When a solution is saturated
mote1985 [20]

Answer:

If more solute is added and it does not dissolve, then the original solution was saturated

If more solute is added and it does not dissolve, then the original solution was saturated. If the added solute dissolves, then the original solution was unsaturated. A solution that has been allowed to reach equilibrium but which has extra undissolved solute at the bottom of the container must be saturate

How is a calorimeter used in this experiment different from the ones used to find the energy content of a snack
Sedbober [7]

Answer:

Kindly check the explanation section.

Explanation:

PS: Note that enough information are not being provided and we do not know the experiment this question is all about. However, some information are provided below which is going to aid in solving when you get access to the main question.

The determination of the heat transferred from one substance to another is one of the important aspect in science. The method in which this heat is being measured is known as calorimetry and the instrument used in this technique is known as the calorimeter.

When the energy content of a snack is needed to be calculated, there is the need use a type of instrument known as bomb calorimeter.

Most of the calorimeters used by students are not so expensive like the used in the industries. Most of these calorimeters operates at a constant pressure while the Bomb Calorimeter operates at constant volume.

The specific heat of copper is 0.385 j/g°c which equation would you use
cestrela7 [59]
Since there's specific heat, you should use Q=mc△T. Depends on if this question also involves phase change or not, you might will need Lf (latent heat of fusion) or Lv (latent heat of vaporisation).
