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:Sol. P base 1 = 10 kpa = 10 × 10^3 pa. P base 2 = 50 × 10^3 pa. v base 1 = 200 cc. v base 2 = 50 cc (i) Work done on the gas = ½ (10+50) ...
Explanation:
Astatine. Because it has the smaller shell of electrons. I believe
We know that in 1 mole there is Avogadro’s number of atoms(no matter of what kind of mole) 6.02 x 10^23.
In order to find the number of moles we just apply the rule of three.
1 mole.............. 6.02 x 10^23.
x mole..............<span>6.02 x 10^25
x = </span>6.02 x 10^25/6.02 x 10^23. = 10^2 = 100 moles
