Which species Al or Cu will have the greater attraction for the chlorine atom?

1 answer:

3 0

Aluminium is an element in group three in the periodic table in period three while copper is a transition element. Aluminium is higher in the reactivity series than copper and therefore it is more reactive than copper. Aluminium has a valence of three and therefore will react with copper forming a strong ionic bond compared to copper which has a valency of 1 or two. Therefore aluminium has greater attraction for chlorine atom

Why does an incomplete combustion reaction occur?

Natasha_Volkova [10]

Incomplete combustion occurs when the supply of air or oxygen is poor. Water is still produced, but carbon monoxide and carbon are produced instead of carbon dioxide. ... Carbon monoxide is a poisonous gas, which is one reason why complete combustion is preferred to incomplete combustion.

Answer: The concentration of A after 865 seconds is 0.00125 M

Explanation:

The integrated rate law equation for second order reaction follows:

$k=\frac{1}{t}\left (\frac{1}{[A]}-\frac{1}{[A]_o}\right)$

where,

k = rate constant = $0.660M^{-1}s^{-1}$

t = time taken = 865 second

[A] = concentration of substance after time 't' = ?

$[A]_o$ = Initial concentration = 0.00440 M

Putting values in above equation, we get:

$0.660=\frac{1}{865}\left (\frac{1}{[A]}-\frac{1}{(0.00440)}\right)$

$[A]=0.00125M$

Hence, the concentration of A after 865 seconds is 0.00125 M

Stereoisomers that are not mirror images of each are ____________ . The chemical and physical properties of two ____________ are

Tanzania [10]

Answer:

Stereoisomers that are not mirror images of each are diasteroisomer . The chemical and physical properties of two diasteroisomers are different. Isomers that differ only in the way atoms are oriented in space are Stereoisomers . Achiral compounds that contain tetrahedral stereogenic centers are meso isomers . Isomers that differ in the way the atoms are connected to each other are structural isomer . Stereoisomers that are nonsuperimposable mirror images of each other are enantiomers . The chemical and physical properties of two enantiomers are identical except in their interaction with chiral substances.

Explanation:

Diasteroisomers are differentiated by the spatial arrangement of atoms, but they are not specular images so they are not enantiomers. In order for two molecules to be diastereoisomers, they must have at least two chiral centers. In one of the centers the substituents are arranged equally in both molecules and in the other they must change.

Enantiomers are specular images but are not superimposable. They have the ability to rotate the polarized light plane

The stereoisomers present the same molecular formula but different spatial rearrangement between their atoms, we can mention the cis and trans isomers where the cis isomers are on the same side of the plane and the trans isomers on opposite sides. They are also known as geometric isomers.

Meso compounds always have more than one asymmetric center and are aquiral. They are distinguished because they present a plane of symmetry.

Structural isomers are those that have different connectivity between their atoms. We can differentiate, for example, metoximethane from ethanol. They will always have the same molecular formula.
