Answer: oxidizing agent:
reducing agent:
Explanation:
Oxidation-reduction reaction or redox reaction is defined as the reaction in which oxidation and reduction reactions occur simultaneously.
Oxidation reaction is defined as the reaction in which a substance looses its electrons. The oxidation state of the substance increases.
Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state of the substance gets reduced.
On reactant side:
Oxidation state of magnesium = 0
Oxidation state of chlorine = 0
On product side:
Oxidation state of magnesium = +2
Oxidation state of chlorine = -1
The oxidation state of chlorine reduces from 0 to -1, it is getting reduced. The substance which gets reduced, oxidize others and called as oxidizing agent.
The oxidation state of magnesium increases from 0 to +2. Thus, it is getting oxidized. The substance which gets oxidized, reduces others and called as reducing agent.
There are 6.022 x 10^23 copper atoms in a mole.
Answer: 3.17
Explanation: you subtract 273 and 250 to get you volume which is 23. Then you divide your mass by your volume ( 73 divided by 23) to get your density.
<span>Ammonium ion when protonated, the result ammonium ion is not electophilic where in the case of iminium ion when protonated the result is electrophilic iminium ion that would have tendency to attract electrons. Protonate means sending a proton to the molecule to form a coordinate bond.</span>
Answer : The electronic configuration of argon (Ar) is,
Explanation :
Element is, Argon (Ar)
Atomic number of argon = 18
The number of electrons = 18
As we know that the number of electrons is equal to the number of protons and the number of proton is equal to the atomic number.
Electronic configuration : It is defined as the arrangement or distribution of electron of atom in a atomic orbital.
Hence, the electronic configuration of argon is,
