True/False : Valence electrons can be easily predicted for transition metals

Chemistry
1 answer:
Mariana [72]3 years ago
8 0

Answer:

False

Explanation:

The answer is false because unlike the main group elements, the transition metals have different valency. They exhibit variable valency and this is because of the presence of the d orbitals.

From his experiments ,j.j Thomson concludes what?
Vladimir [108]

Answer:

Thomson made the following conclusions: The cathode ray is composed of negatively-charged particles. The particles must exist as part of the atom, since the mass of each particle is only ∼ 20001​start fraction, 1, divided by, 2000, end fraction the mass of a hydrogen atom.

Classify each process by its individual effect on the entropy of the universe, s. hydrogen peroxide slowly decomposing into wate
Jobisdone [24]
Hydrogen Peroxide slowly decomposing into water and oxygen increases the entropy of the universe. Any reaction of a system always increases the degree of the orderliness of the universe. Decomposition is one of the best examples of increasing the entropy. This is when substance is broken down further to elements or other compounds.

Classify methanal according to the position of the c=o group
seraphim [82]

Answer :  Methanal also known as Formaldehyde CH_{2}O is a chemical Aldehyde which contain ( -CHO) group.

Explanation :

In organic chemistry, a carbonyl group is a functional group which contain a carbon atom double-bonded to an oxygen atom i.e, ( C=O).

     If carbonyl group is present in a compound then it can be a carboxylic (RCOOH), aldehyde (RCHO), ketone (RCOR'), ester ((RCOOR') or amide (RCONR'R") group.

Here are some functional groups naming according to the<em> IUPAC</em> rules and image also attached,

Carboxylic acid   →    (RCOOH)    →    ( name end in 'OIC ACID' )

Aldehyde             →    (RCOH)       →    ( name end in 'AL' )

Ketone                 →    (RCOR')       →    ( name end in 'ONE' )

Ester                     →    (RCOOR')    →    ( name end in 'ATE' )

Amide                   →    (RCONR'R") →    ( name end in 'AMIDE' )

In an aldehyde, atleast one hydrogen atom must be attached to the carbonyl carbon. For an aldehyde, remove ( -e) from alkane name and add ( -al) at the end of the compound.

Methanal is the IUPAC name for Formaldehyde.
