18. identify the three conditions under which ionic reactions can run to completion, and write an equation for each.
erastovalidia [21]

Formation of a gas, formation of a precipitate and formation of a slightly ionized product are the cases for the completion of ionic reactions.

<h3>What are the three conditions under which ionic reactions completed?</h3>

The three conditions under which ionic reactions can run to completion i.e. formation of a gas, formation of a precipitate and formation of a slightly ionized product.

K+(aq) + Br−(aq) + Ag+(aq) + C2H3O2−(aq) → K+(aq) + C2H3O2−(aq) + AgBr(s)

Mg2+(aq) + SO42−(aq) + Ba2+(aq) + 2NO3−(aq) → Mg2+(aq) + 2NO3−(aq) + BaSO4(s)

So we can conclude that formation of a gas, formation of a precipitate and formation of a slightly ionized product are the cases for the completion of ionic reactions.

Molecular evidence has led taxonomists to group bilaterally symmetrical animals in one of three clades: Deuterostomia, Lophototr
Likurg_2 [28]

Answer:

One distinguishing characteristicof all three clades i.e Deuterostomia, Lophototrochozoa, or Ecydysozoa are  balstopore development, internal body cavity and exoskeleton respectively

Explanation:

Apart from molecular difference, there exist structural differences between the three clades, which are as follows –  

Deuterostomia – The development of embryo is different from the protostomes as the first opening in this clade is anus and the blastopores develops into the anus.

Lophototrochozoa – They do not have ant distinguished internal body cavity. Organs with in coelom can move freely. For example - flatworm

Ecydysozoa – have the ability to shed their tough and flexible exoskeleton i.e cuticle , several times throughout their life span
