Answer:
No. They typically are not identical.
Explanation:
Atom's electrons can be in different states
Yes, It is important to know the volume of Unknown acid or base to be titrated.
Titration is carried out in order to find out the concentration (i.e. molarity) of unknown acid or base. In this process a standard solution of acid or base is taken and is titrated with known volume of of titrant. At end point (neutralization) the amount of standard titrant utilized is calculated and following formula is employed to calculate the unknown concentration of unknown solution.
M₁V₁/n₁ = M₂V₂/n₂
The answer is (2) 2, because a total of 6 electrons is transferred. We can know the electron transferred number form Mg to Mg2+ ion. There is 3 Mg involved and two electrons per atom. So total is 6,
You haven't given the synthesis reaction but in general, In the simplest cases, a synthesis reaction occurs when two different atoms or molecules interact to form a different molecule or compound. Most of the time, when a synthesis reaction occurs, energy is released and the reaction is exothermic. However, an endothermic outcome is also possible. Synthesis reactions are one of the major classes of chemical reactions, which include but are not limited to, single displacement, double displacement, and combustion reactions.
