Please help!!! Bob puts several pieces of dry ice inside an empty water bottle and covers the spout with a balloon. After 5 minu

tes the balloon is inflated. Elaborate on what process is occurring.
A) The expanding gas is exerting pressure and doing work on the walls of the balloon causing it to inflate.
B) Quick moving molecules of the developing balloon use the gas to create work and put energy into the system.
C) The slow moving particles of the gas are transferring entropy to the expanding balloon causing it to weaken.
D) Energy is converted to enthalpy as the compression dry ice particles occurs and the gas collides with other gas particles.

Answer:

A) The expanding gas is exerting pressure and doing work on the walls of the balloon causing it to inflate.

Explanation:

As the gas is gradually expanding showing an increase in the volume that exerts pressure on the walls of the balloon causing it to inflate.

Balance the following skeleton reactions and identify the oxidizing and reducing agents:(b) CrO₄²⁻(aq) + Cu(s) → CrOH₃(s) + CuOH
andrew-mc [135]

The balanced skeleton reactions are given below

2CrO₄²⁻(aq) + 3Cu(s)  +8H_{2} O(l) → 2Cr(OH)₃(s) + 3Cu(OH)₂(s) + 6OH^{-}(aq)

The oxidising agent and  reducing agents are Cr and  Cu .

There are following steps involve in balance redox reaction in basic medium .

  • First divide the reaction into two half reactions which give oxidation and reduction half reaction.
  • Then balance the elements other than oxygen and hydrogen atom.
  • Balance the oxygen atom by adding H_{2} O where number of oxygen is less .
  • Balance the hydrogen atom by adding H^{+} on another side of where water molecule added.
  • Add OH^{-} ions to both sides to neutralize  H^{+} ion.
  • Combine  H^{+} and OH^{-} ion to make H_{2} O .
  • Balance the charge by adding e^{-} .
  • Add the half reaction  .

The species which reduces the other species in the redox reaction is called oxidizing agent . Similarly , the species which oxidize the other species in the redox reaction  is called reducing agent .

What is the molarity of a NaOH solution when 22.14 mL of 0.105 M oxalic acid is needed to
jeka57 [31]

The molarity of the NaOH solution required for the reaction is 0.186 M

We'll begin by writing the balanced equation for the reaction

H₂C₂O₄ +2NaOH —> Na₂C₂O₄ + 2H₂O

From the balanced equation above,

The mole ratio of the acid, H₂C₂O₄ (nA) = 1

The mole ratio of the base, NaOH (nB) = 2

From the question given above, the following data were obtained:

Volume of the acid, H₂C₂O₄ (Va) = 22.14 mL

Molarity of the acid, H₂C₂O₄ (Ma) = 0.105 M

Volume of the base, NaOH (Vb) = 25 mL

<h3>Molarity of the base, NaOH (Mb) =? </h3>

MaVa / MbVb = nA/nB

(0.105 × 22.14) / (Mb × 25) = 1/2

2.3247 / (Mb × 25) = 1/2

Cross multiply

Mb × 25 = 2.3247 × 2

Mb × 25 = 4.6494

Divide both side by 25

Mb = 4.6494 / 25

<h3>Mb = 0.186 M</h3>

Therefore, the molarity of the base, NaOH solution is 0.186 M

Acetylene reacts with hydrogen in the presence of a catalyst to form ethane according to the following reaction:
ElenaW [278]

Answer:

mole fraction of acetylene in the original mixture = 0.29

Explanation:

The application of Dalton's law of partial pressure comes into play.

From Partial pressure = Mole fraction x total pressure.

The step by step calculation is as shown in the attachment.
