Answer:
Explanation:
2NO3, Ca2+
Spectator ions exists in both sides of the equation. These ions are present in both sides thus cancel out (they do not contribute to reaction...i.e. they only watch or spectate ;) )
Answer:
Haploid - 13
Triploid - 39
Tetraploid - 52
Trisomic - 27
Monosomic - 25
Explanation:
A haploid organism has half the chromosome number of a diploid version, hence 26/2 = 13
A triploid organism has 3 sets of a haploid chromosomes, hence 13 x 3 = 39
A tetraploid is double of a diploid, 26 x 2 = 52
Trisomic organisms have one extra chromosome in addition to the normal diploid. Hence 26 + 1 = 27
Monosomic organism has one less chromosome than the normal diploid. Hence 26 - 1 = 25

Yes sir that’s what I do for the kids and the kids I don’t have any money for that one so that’s what I want to learn and how to do that I don’t have any money for that money for you to get for you
Reduction Reaction:
Ag⁺ + 1e⁻ → Ag ------ (1)
Oxidation Reaction:
NO₂⁻ → NO₃⁻ + 2e⁻
Balance Oxygen atoms, by adding H₂O to side having less number of O atoms, and H⁺ to side having greater number of O atoms.
NO₂⁻ + H₂O → NO₃⁻ + H⁺ + 2e⁻
Balance the H⁺'s,
NO₂⁻ + H₂O → NO₃⁻ + 2 H⁺ + 2e⁻ ------ (2)
Multiply eq. 1 by 2 to balance the number of electrons in overall reaction.
2 Ag⁺ + 2e⁻ → 2 Ag ----- (3)
Compare eq. 2 and 3,
NO₂⁻ + H₂O → NO₃⁻ + 2 H⁺ + 2e⁻
2 Ag⁺ + 2e⁻ → 2 Ag
_______________________________________
NO₂⁻ + H₂O + 2 Ag⁺ → NO₃⁻ + 2 Ag + 2 H⁺
