Please help!!!! Chem question

Answer : The net ionic equation will be,

Ba^{2+}(aq)+SO_4^{2-}(aq)\rightarrow BaSO_4(s)

Explanation :

In the net ionic equations, we are not include the spectator ions in the equations.

Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.

The given balanced ionic equation will be,

Ba(OH)_2(aq)+H_2SO_4(aq)\rightarrow 2H_2O(aq)+BaSO_4(s)

The ionic equation in separated aqueous solution will be,

Ba^{2+}(aq)+2OH^-(aq)+2H^{+}(aq)+SO_4^{2-}(aq)\rightarrow BaSO_4(s)+2H^+(aq)+2OH^{-}(aq)

In this equation, H^+\text{ and }OH^- are the spectator ions.

By removing the spectator ions from the balanced ionic equation, we get the net ionic equation.

The net ionic equation will be,

Ba^{2+}(aq)+SO_4^{2-}(aq)\rightarrow BaSO_4(s)

Corn plants may be tall (TT or Tt) or short (tt). The breeding of two parent corn plants results in offspring that are all tall.
zubka84 [21]

Answer:

0%

Explanation:

  • The probability that both of the parents are homozygous recessive is zero.
  • In our case, The gene for tallness is dominant over the gene for dwarfism
  • Therefore; TT is homozygous dominant while tt is homozygous recessive and Tt is heterozygous.
  • Heterozygous genotype (Tt) will exhibit a tall phenotype.
  • When two parents are crossed and all the offsprings are tall then the possible genotype of the parents is either;
  1. Homozygous dominant for both parents or  

       TT x TT

    2. One parent is homozygous dominant and the other is homozygous recessive.

        TT x Tt

  • Therefore, the probability of having both parents as homozygous recessive when all the offspring are tall is Zero.
