The hydrogenation of unsaturated hydrocarbons is

Chemistry
1 answer:
Ann [662]3 years ago
6 0

Answer:

The metal catalyst in catalytic hydrogeation process increases the rate of reaction by lowering the activation energy of the reaction, by allowing the reaction take place at a much lower temperature than it would have without the metl ctalyst.

This catalysis is regarded as heterogeneous or surface catalysis.

Explanation:

The hydrogen is first bonded to the metallic powder as the initial step of the reaction.

Arrange the sublevels in ascending order by the number of electrons they can contain. p sublevel s sublevel d sublevel f subleve
inn [45]

Electronic configuration of the atom describes  the arrangemnet of electrons in different shells and subshells ( sublevels).

Now , there are 4 types of sublevels: s, p , d and f . These sublevels have orbital which are spaces with high probability of having an electron and each orbital can have maximum 2 electrons.

Therefore,

s-sublevel has 1 orbital - it can have maximum 2 electrons.

p-sublevel has 3 orbitals - it can have maximum 6 electrons

d-sublevel has 5 orbitals - it can have maximum 10 electrons

f-sublevel has 7 orbitals - it can have maximum 14 electrons.

Hence, the acsending order of sublevels in terms of maximum number of electrons is:

<h2>s < p < d < f</h2>

Many elements bond to carbon by exchanging electrons. true or false.
Sliva [168]
If a metal is bonded to carbon, they form ionic bonds. If a nonmetal forms a bond with carbon, they form covalent bond. Ionic bond requires metals to give away electrons to form cations and nonmetal to gain/accept electron to form anions. Covalent bond requires sharing of electrons between both elements. So if you meant exchange as in covalent bond, then no. Not many nonmetal elements form bonds with carbon as there are more metal elements in the periodic table.

4 Compare What is the difference between<br> temperature, thermal energy, and heat?
Ivahew [28]

Answer:

The term temperature refers to the average amount of heat or the motion energy of particles in a substance. It measures the hotness and coldness of a substance. If an object has particles that move very fast, then it has a high temperature.

Temperature is different from the term thermal energy. Thermal energy is the total motion energy of particles in a substance. The movement of particles is always dependent on their number. If an object contains many particles, then it has greater thermal energy.

On the other hand, Heat is the energy that is involved in the movement of particles between objects that have different temperatures, particularly from an object with a high temperature to an object with a low temperature.
