a. Spectator ions are the ones that are present but does not enter into the actual chemical reaction.
b. Na⁺ and NO₃⁻ ions are spectator ions involved in this above mentioned reaction
<u>Explanation:</u>
- In redox reactions, for example reaction of aqueous silver nitrate and aqueous sodium chloride, silver chloride settles down as a precipitate by the addition of Ag⁺ ion from AgNO₃ and Cl⁻ ions from NaCl .
- The other 2 ions that is NO₃⁻ ion and Na⁺ ion in the reaction do not enter into the reaction and they are called as Spectator ions.
This can be expressed as the following equation,
AgNO₃(aq) + NaCl(aq) →AgCl(s) + NaNO₃
Answer:
Density is the mass of an object divided by its volume. Density often has units of grams per cubic centimeter (g/cm3). Remember, grams is a mass and cubic centimeters is a volume (the same volume as 1 milliliter).
Explanation:
Answer:
A
Explanation:
Coupled reactions are reactions in which endergonic reactions obtain the energy to go forward from exergonic reactions.
When benzene diazonium chloride interacts with phenol, the para position of the phenol molecules is associated with the diazonium salt, resulting in
p-hydroxyazobenzene. The coupling reaction is the name given to this process.
Answer:
Yes
Explanation:
AsH3 contains a polar bond.
I would say a number about 545.
