Ethene will not typically react with hydrogen gas through simple bimolecular collisions. Using the picture, explain how this rea

ction becomes possible.
A: A metal surface is catalyzing the reaction by speeding up the kinetic energy of hydrogen gas and, as a result, breaking its bonds so that it can react with ethene.

B: A metal surface is acting as a catalyst and lowers the activation energy of bond breaking of hydrogen gas.

C: Ethene is stabilized by a metal surface and hydrogen gas catalyzes the metal surface so that it can react with ethene.

D: Ethene is catalyzed by a metal surface and, therefore, raises the activation energy of hydrogen gas breaking apart.

Which of the following represents a chemical property of hydrogen gas?
Hoochie [10]

Answer: The option that represents the chemical properties of Hydrogen gas is A (It explodes with a flame.)

Explanation: Hydrogen gas is the lightest of all gases and the most abundant element in the universe. It's physical and chemical properties are the characteristics that distinguishes it from any other substance.

chemical properties of Hydrogen are the characteristics that determine how it will react with other substances or change from one substance to another. They include:

-It burns in air or oxygen to produce water.

-When mixed with air it can spontaneously explode by spark, flame or sunlight. I hope this helps. thanks.

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.

Why do atoms gain or lose electrons?
Aleksandr [31]

Answer:kapil

Explanation:

Atoms lose electrons, if an electron gets more energy than then binding energy of the electron. This may be because of a collision with a charged particle or because of absorbtion of a photon. In a metal, there are just other positive charges nearby. The electron is not lost, but shared.
