When writing a formula for a compound having a transition metal in it, _____.

Chemistry
1 answer:
DanielleElmas [232]3 years ago
3 0

Answer:

The correct option is;

It is always necessary to include a Roman numeral after the symbol of the metal

Explanation:

The transition metals can form ionic compounds with other elements by giving different number of electrons such that the transition metals can combine to form compounds in which they have different oxidation states

Therefore, in a compound formed by a transition metal, the value of the transition metal's valency or oxidation state in the compound is indicated by the inclusion of an equivalent Roman numeral after the transition metal in the name of the chemical formula of the compound

NH3 + HCI —> NH4CI synthesis O decomposition O single replacement O double replacement​
wlad13 [49]

Answer:

synthesis

Explanation:

The reaction given is a synthesis reaction or combination reaction.

Given equation:

                        NH₃  +  HCl   →   NH₄Cl

In a synthesis reaction, a single product is formed from two or more reactants

                          A + B →  C

The formation of compounds from the union of constituent elements also falls into this category.

So the given reaction is a synthesis reaction.

In a decomposition reaction two or more products are formed from a single reactant

In a single replacement reaction, one substance replaces another.

In double replacement reactions partners in a chemical specie are exchanged.

Therefore the given reaction is a synthesis reaction

Does ccl4 has resonance structures
krek1111 [17]

Answer:

No, CCl₄ is 4 covalent C-Cl single bonds with a Tetrahedral geometry.

Explanation:l

For resonance structures to exist the molecule must have alternating single-double bonds. H₂C = CH - CH₃ <=> H₃C - CH = CH₂ resents a simple compound with a resonance structure system. This means that the π-bond electrons are distributed across all carbons in the molecular backbone. I would recommend internet searching for Danial Weeks 'Pushing Electrons' for a comprehensive review of molecular resonance structures. It is a brief, but easy to follow treatment of simple to complex structures containing resonance systems.

Hope this helps. Doc :-)
