Answer: Chromium is less reactive as compared to Aluminium as it can not easily electrons as aluminium.
Explanation:
The arrangement of metals in a series according to the decreasing order of their reactivity is called reactivity series.
The metals that are placed above hydrogen are more reactive and those below hydrogen are less reactive.
A metal placed above another metal can displace lower metal from its salt solution. Thus a metal placed above in series is more reactive than metals placed below it.
As aluminium can easily lose electrons as compared to chromium , it is more reactive than Chromium.
Answer:The moles of H+(aq) equal the moles of OH-(aq)
Explanation:
Lewis structures are also known as Lewis dot diagrams or Lewis dot formulas. This <span>diagrams depict the </span>bonding<span> between </span>atoms<span> of a </span>molecule<span> and the </span>lone pairs<span> of </span>electrons<span> that may exist in the molecule. </span><span>A Lewis structure can be drawn for both </span>covalently <span>bonded molecule and </span><span>coordination compounds.
The l</span>ewis structure of the hypochlorite ion is attached below. From the lewis structure, it can be seen that, in hypochlorite ion Cl and O shares one pair of electrons. Hence, bond order of<span> hypochlorite ion is one. </span>
Answer:
A). half, higher
Explanation:
The Formal charge is elaborated as the 'allocated charge to a molecules' atom' on the basis of the assumption that the electrons present in the chemical bond are equally split among the atoms. It is estimated by 'halving the no. of bonding electrons that encircle the atom.
While Oxidation number is characterized as the 'hypothetical charge of an atom that is present within a molecule.' It is also defined as 'the actual number of lost or gained electrons or the rate at which the electrons are gained or lost by an atom to develop a chemical bond along with the other atom.' It is <u>calculated by allocating or sharing the electrons having the higher electronegativity belonging to a specific bond with the other</u>. Thus, <u>option A</u> is the correct answer.
The answer is C because I kno
