Chemistry
1 answer:
Sedaia [141]3 years ago
5 0

Answer:

The correct option is D

Explanation:

A physical change is a change in which no new substance is formed and can be easily reversible.

Of the options provided, option D is correct because gaseous water (steam) can be converted to solid water (ice) through freezing and can be reversed by heating up the solid water. Thus, this process does not involve the formation of any new substance.

Note that the processes of freezing and heating described must pass through the liquid phase.

1) Answer is: 5.
Chemical dissociation of aluminium sulfide in water:
Al₂S₃(aq) → 2Al³⁺(aq) + 3S²⁻(aq).
There are five ions, two aluminium cations and three sulfide anions.

2) Answer is: 4.
Chemical dissociation of aluminium fluoride in water:
AlF₃(aq) → Al³⁺(aq) + 3F⁻(aq).
There are four ions, one aluminium cation and three fluoride anions.
Aluminium has oxidation +3, because it lost three electrons, to gain electron configuration as noble gas neon.

Suppose a healthy individual experiences a surge in plasma calcium. subsequently, where would one expect to find the greatest am
victus00 [196]

One can expect to find the greatest amount of hydrolyzed pth when, entering the nephrons.

<h3><u>Where would one expect to find the greatest amount of hydrolyzed pth ?</u></h3>
  • In a healthy person, the body will respond by excreting calcium and PTH byproducts if plasma calcium is higher than usual. The nephron is a solid predictor since the kidneys are where excretion takes place.
  • A) is false since PTH, not the hydrolyzed compounds, is produced by the parathyroid gland.
  • One would anticipate significant amounts of PTH exiting the liver rather than entering since the liver hydrolyzes PTH.
  • The largest concentration would still be in the nephrons, even if it is possible that some hydrolysis products will be in systemic circulation (and therefore penetrate the bones).
  • The cortical bone, which is the outermost part of the bone, has a network of small tubes called haversian canals that let blood vessels and nerves to pass through them.
