What is the hybridization of the central atom, electron geometry, and molecular geometry of H3CCCH?

Chemistry
1 answer:
DIA [1.3K]3 years ago
6 0

Answer:

Hybridization: sp

Electron geometry: linear

Molecular geometry: linear

Explanation:

H₃CCCH can also be written as its Lewis structure which is shown in the figure attached. The figure shows that the central carbon atom makes a single bond with CH₃ and a triple bond with CH. This means that the hybridization of the carbon is sp and both the electron and molecular geometry are linear with an 180° bond angle.

MrMuchimi

Answer:

Fe

Explanation:

The cell potential is:

ΔE°cell = E°red(red) - E°red(oxid)

Where, E°red(red) is the reduction potential of the substance that is reducing, and E°red(oxid) is the reduction potential of the substance that is oxidizing. For the reaction be spontaneous and happen, ΔE°cell > 0.

The reduction takes place in the cathode, which is the negative pole, and the oxidation in the anode, which is the positive pole. So, the electrons flow from the positive pole to the negative pole (anode to cathode).

Then, if the voltmeter measured a negative potential, it means that is was attached incorrectly. So, the anode is Fe.

What does the energy hill represent on an energy diagram?
Butoxors [25]

Answer:

The correct answer is option D.

Explanation:

When a chemical reaction proceeds the reactants are converted into products. The energy hill represents the potential energy of the reaction.

There are two conditions: If the reaction is endothermic than the energy of the products is greater than the energy of the reactants and  ΔH  is positive. This energy gain is shown in the form of a peak.  In an exothermic reaction, the energy of the products is lower than the reactants and  ΔH  is negative.

So the suitable option is D which states that the reaction is endothermic and the potential energy gained by the products is higher when a reaction proceeds.

Explain how atoms are held together in covalent bonds. Give an example of a covalent compound.
asambeis [7]

Answer:

Explanation:

Atoms are held together by covalent bonds when they share electrons between themselves.

Covalent bonds are bonds that are formed between non-metals usually with a low electronegative difference between them. In this bond type, two non-metals donate electrons which are shared between the combining atoms and this makes them both like the corresponding noble gases. The shared electrons is what forms the covalent bonds.

An example of covalent bond is HCl, H₂S, SO₂, CO₂, O₂ etc
