A kinetics experiment is set up to collect the gas that is generated when a sample of chalk, consisting primarily of solid CaCO3

, is added to a solution of ethanoic acid, CH COOH. The rate of reaction between CaCo, and CH3COOH is determined by measuring the volume of gas generated at 25°C and I atm as a function of time. Which of the following experimental conditions is most likely to increase the rate of gas production?
(A) Decreasing the volume of ethanoic acid solution used in the experiment acid solution used in the experiment experiment is performed
(B) Decreasing the concentration of the ethanoic
(C) Decreasing the temperature at which the

(D) Decreasing the particle size of the CacO, by grinding it into a fine powder

Explanation:

To produce more gases by increasing the rate of the chemical reaction, if we grind the chalk into powder, this should walk.

The rate at which chemical reactions takes place is a measure of the speed of  the reaction.

Some factors control the rate of chemical reactions. They are:

  1. Nature of reactants
  2. Concentration of reactants or pressure if gaseous.
  3. Temperature
  4. Presence of a catalyst
  5. Sunlight

The most applicable in this scenario is grinding the chalk into fine powder. This process increases the surface area exposed. Surface area exposed proportionally affects the rate of a reaction.

If the concentration of the stock (provided) Cu(NH3)42 was 0.041 M, what concentration will the Cu2 be in beaker?
kodGreya [7K]

Answer:

[Cu^{2+}]=0.041 M

Explanation:

Hello!

In this case, since the molarity of a solution is defined in terms of the moles of the solute and the volume of solution, given that the concentration of Cu(NH₃)₄²⁺ is 0.041 M, and there is only one copper atom per Cu(NH₃)₄²⁺ ion, we can compute the concentration of Cu²⁺ as shown below:

[Cu^{2+}]=0.041\frac{molCu(NH_3)_4^{2+}}{L}*\frac{1molCu^{2+}}{1molCu(NH_3)_4^{2+}} =0.041 \frac{molCu(NH_3)_4^{2+}}{L}

[Cu^{2+}]=0.041 M

Best regards!

What is the change in temperature when 75 grams of water releases -2657 J of energy? The specific heat of water is 4.18 J/g°C
Naily [24]
I think the answer for this is 4702.5 J/g*k Depending on if it is water as a solid liquid or gas. I used water as a liquid when I solved it. J=(75g)(4.18 J/g*k)(15K)

Explain using the particle theory why objects generally expand when heated and contract when cooled?
seraphim [82]
When heated, particles vibrate faster, thus increasing the distance between one another. The distance between these particles results in changes of state. Therefore, increased molecular motion results in expansion of an object. This works vice versa for cooling. As the vibrations slow down, the particles become closer together. This results in contraction.
