8.10in^2=52.25796cm^2

1 in^2=6.4516cm^2

8.10in^2*6.4516cm^2/1 in^2

8.10in^2*6.4516cm^2= 52.25796 cm^2

OverLord2011 [107]

Question: The question is incomplete. Below is the complete question and the answer;

While ethanol (CH3CH2OH is produced naturally by fermentation, e.g. in beer- and wine-making, industrially it is synthesized by reacting ethylene CH2CH2) with water vapor at elevated temperatures. A chemical engineer studying this reaction fills a 50.0 L tank at 22. °C with 24. mol of ethylene gas and 24. mol of water vapor. He then raises the temperature considerably, and when the mixture has come to equilibrium determines that it contains 15.4 mol of ethylene gas and 15.4 mol of water vapor The engineer then adds another 12. mol of water, and allows the mixture to come to equilibrium again. Calculate the moles of ethanol after equilibrium is reached the second time. Round your answer to 2 significant digits.

Answer:

Number of moles of ethanol = 11 mol

Question 4 (1 point)

а о

Explanation:

 The given cation:

           (Rf₂Al₂F₃)³⁺

The oxidation number gives the extent to which a specie is oxidized in a reaction.

This number is assigned based on some rules:

  • Elements in combined state whose atoms combines with themselves have an oxidation number of zero.
  • The charge carried on simple ions gives their oxidation number.
  • Algebraic sum of all the oxidation numbers of atoms in neutral compound is zero. In an ion with more than one kind of atom, the charge on it is the oxidation number.

for the specie given;

Known:

  oxidation number of Al = +3

                                      F = -1

                          charge = +3

    let the oxidation number of Rf = k

        2k + 2(3) + 3(-1) = +3

          2k + 6 - 3 = 3

            2k = 0

              k = 0

The oxidation state of rutherfodium is 0

Which would have the lowest input force?
Afina-wow [57]

Answer:

A long lever with the fulcrum as close as possible to the load

Explanation:

If F be the effort , W be the weight , L₁  be the distance of load from fulcrum and L₂ be the distance of effort from the fulcrum ,

Taking moment of force about the fulcrum , we have

W x L₁ =  F x L₂

F = W x ( L₁ /  L₂ )

F will be minimum when L₁ will be minimum .

Hence  fulcrum should be as close as possible to the load.
