How do you figure out the saturation of a substance

Biology
1 answer:
geniusboy [140]3 years ago
4 0

Answer:

Divide the mass of the dissolved compound by its molar mass to calculate the number of moles. In our example, this would be: Number of moles (NaNO 3)=21.9g /85 g/mole= 0.258 moles.

Explanation:

A solution is saturated if there is visible solute that is not dissolving in the solution. Additional solute added to an already saturated solution just forms a layer of solute separate from the rest of the solution, according to a chemistry lesson posted by Mountain Empire Community College.

If the temperatures of solutions are increased, the solubilities of solutes increase, which means more solute can dissolve in a warmer solution versus one at room temperature. Substances have set solubilities in different solvents, depending on the conditions of temperature and pressure. The normal conditions of temperature and pressure are 25 degrees Celsius and one atmosphere. Several factors affect the solubility of a substance. Temperature, pressure, size of the solute and stirring of the solution all contribute to the amount of solute that can dissolve.

How are the studies performed on rainbow trout ( Oncorhynchus mykiss) and the moss Pleurozium schreberi and the desert shrub Atr
Sergio039 [100]

Answer:

Both studies support the concept that species operate within a narrow optimum temperature range and are coupled to enzymatic activity.

Explanation:

The studies shown in the question above started from the same concept to establish the scientific experiment and had the same objective related to the investigation as temperature changes in the environment where these organisms live influences the enzymatic activity and, therefore, the functioning of their organism, being able to including modifying the environment around them. In summary, we can say that the studies sought to support the concept that species operate within a narrow range of optimal temperature and are coupled with enzymatic activity.

Planarians lack dedicated respiratory and circulatory systems. This deficiency does not cause a problem because ________.
ZanzabumX [31]

Answer:

Most cells within planarians tend to be very close to their gastrovascular cavity, in addition to their external environments. Also, planarians have the ability for oxygen and carbon dioxide to diffuse through the cells on their body walls: this makes it unnecessary for these varieties of flatworms to need a dedicated bodily system.

I think the deficiency of dedicated respiratory and circulatory systems in Planarians does not cause a problem because none of their cells are far removed from the gastrovascular cavity or from the external environment. Planarians are free-living flatworms and form the class Turbellarians in the Phylum Platyhelminthes. Flatworms have three tissue layers, that is the ectoderm, mesoderm, and endoderm.

A pea plant is heterozygous for both seed shape and seed color. S is the allele for the dominant, spherical shape characteristic
kati45 [8]

So, you would make a punnet square. You would put the capital S and lowercase s on the top of it and then the capital Y and lowercase y on the side. Then you should have SY, sY, Sy, and sy as your outcomes.

how does the content of the blood change when it leaves the right atrium and enters the right ventricle​
Nastasia [14]
Blood first enters the heart's right atrium. A muscle contraction forces the blood through the tricuspid valve into the right ventricle. When the right ventricle contracts, blood is forced through the pulmonary semilunar valve into the pulmonary artery. Then it travels to the lungs
