photoshop1234 [79]

Answer:

intracellular; extracellular

Explanation:

Intracellular fluid compartment is system which includes all the fluid which is enclosed in the cells by the plasma membranes of these cells. It lies in the cells and acts as the principal component of cytoplasm. ICF makes up about 2/3 of total water in human body.

Extracellular fluid is system which surrounds all the cells in body. The fluid has two primary constituents which are - fluid component of blood (known as plasma) and interstitial fluid (IF) which surrounds all the cells except blood. It accounts for other 1/3 of water content of the body.

Nimfa-mama [501]

The arrow that represents the transition in which dew is formed would be arrow 4.

<h3>How is dew formed?</h3>

Dew is formed by condensation. Condensation, in itself, involves a transition from a gas phase to a liquid phase.

From the diagram, the arrow that represents a transition from gas to liquid is arrow 4.

Thus, the arrow that represents the transition that leads to the formation of dew would be arrow 4.

You chill your reaction in an ice bath when adding nitric acid to the sulfuric acid. why?
Andrej [43]
The reaction of nitric acid and sulfuric acid is highly exothermic so it releases a lot of heat. If the temperature is not controlled, the reaction could go into thermal runaway, which is potentially extremely hazardous.

Calculate the standard cell potential of the following cell at 25°C. Sn(s) | Sn2+(aq) || Cu2+(aq) | Cu(s).
Semmy [17]

Answer:

0.48 V

Explanation:

Usually in the cell notation, the left side shows oxidation. So,

Oxidation half reaction:

Sn_{(s)}\rightarrow Sn^{2+}_{(aq)}+2e^-    E^o_{ox}=-E^o_{red}=-(-0.14\ V)=0.14\ V

Reduction half reaction:

Cu^{2+}_{(aq)}+2e^-\rightarrow Cu_{(s)}    E^o_{red}=0.34\ V

E^o_{cell}=E^o_{ox}+E^o_{red}= (0.14+0.34)\ V=0.48\ V
