In order to increase the rate of a reaction and to decrease the magnitude of the activation energy, compounds containing transitional elements or their oxides are used.
One of the fundamental behaviours of these metals are heterogenous catalysis. In this procedure, the 3d and 4s orbitals are usually free of electrons, and it allows to create bonds (with higher covalent character) with reactants, which will make the reactants to collide in the correct angle more efficiently.
Usage of these compounds in the reactions of gases is a special feature.
Given below a list of compounds used as catalysts and their usage.
- Vanadium pentoxide or vanadium metal - To convert sulphur dioxide into sulphur trioxide in the manufacture of Sulphuric(VI) Acid.
- Iron metal - Manufacture of ammonia by Haber's process
- Chromium(III) Oxide or Zinc(II) Oxide - Manufacture of methanol using carbon monoxide
- Titanium metal and compounds - To synthesize polymers out of alkenes (e.g. polythene).
- Nickel metal - To saturate unsaturated hydrocarbons
- Cobalt compounds - To synthesize carbonyl compounds

How does zinc behave and react?
Zincis a highly electropositive element and can displace hydrogen acids.It reacts with non metals to form binary compounds like ZnO,ZnS.
Why does the isotope of the same element similar from each other?
Isotopes of the same element have the same number of protons. They will also have the same number of electrons in a neutral state. Where they differ is in the number of neutrons in the nucleus. The chemical properties of an element are almost entirely determined by its electron structure, since chemical bonds can be understood as the transfer or sharing of electrons. This means isotopes of the same element will behave in the same way chemically. They will form the same chemical compounds and be largely indistinguishable from their isotopic brethren.
What element behaves partly as an alkaline metal as well as a halogen element?
In some specific circumstances, hydrogen can behave partly as an alkaline metal as well as a halogen element. This is due to the similarity of the two groups.
What correlation exists between an element's electronegativity and its ability to behave as an oxidizing agent?
The greater the electronegativity, the stronger an oxidant that element will be. The lower its electronegativity, the stronger a reducing agent it will be.
What element would you expect to behave the most like calcium?
Calcium is in group 2/IIA, so the other elements in that group would be expected to behave most like calcium.
How does the Neodymium element behave?
It is magnetic.
Which element is a gas that can behave as an alkali metal?
Hydrogen.
How does zinc behave and react?
Zincis a highly electropositive element and can displace hydrogen acids.It reacts with non metals to form binary compounds like ZnO,ZnS.
Why are carbon based compounds lumped together as a separate subject within the study of chemistry?
Carbon-based compounds behave differently from compounds based on other elements.
Which element will behave similarly to C in the periodic talbe?
si
Which element would you expect to behave the most like the carbon?
Ge Germanium
Which element would you expect behave the most like carbon?
Ge Germanium
Are enzymes an organic?
In general organic contains carbon molecules and/or those related to life. It is the chemistry of carbon containing compounds. Inorganic is everything else and generally do not contain carbon (with some exceptions). However, enzymes are generally organic
What element has not really an alkali metal but since you have only 1 electron you behave like them?
Hydrogen
Why does the isotope of the same element similar from each other?

This means isotopes of the same element will behave in the same way chemically. They will form the same chemical compounds and be largely indistinguishable from their isotopic brethren.
Why do all atoms of an element have the same chemical prperties?
Because they are all the same type of atoms. Oxygen is an element. If you have 10 oxygen atoms, they will all behave like oxygen, since they are the same element.
