NaOH is hygroscopic
Explanation:
- A standard solution is a solution of known molarity or concentration.
- Standard solutions are used in determining the stoichiometric amount of desired species in an experiment.
- A solution of NaOH is not a standard solution because NaOH is hygroscopic in nature.
- By this, NaOH absorbs moisture from the atmosphere in considerable amount.
- This implies that one must find an air free environment to store and use the compound and accurately quantify it.
- This is why a solution of NaOH is standardize with a primary standard.

<h2>
<u>Relationship between predator and prey in a balanced ecosystem.</u></h2>
Predators grow along with their victims. Over time, prey animals are now developing and avoiding themselves to get eaten by their predators. Such tactics and modifications can take many forms that make their work easier, including disguise, mimicry, defense mechanisms, flexibility, distance, habits and even tool use.
Though fact an equilibrium appears to occur within an ecosystem between predators and prey, there are several factors which affect it, including the birth and death rates of predators and preys.
Question 17:
False; cutting hair would change what it looks like but, braiding it keeps it the same substance it is.
Question 18 :
My best guess would either be A or D. I would lean more towards D because if there are different mixtures then it depends on what you are mixing.
Hope it helps in some way. <3
