Factors that limit a technological design are called constrains. But why?

1 answer:

3 0

The factors that limit a technological design can be physical and social. The physical limitations are constraints due to nature itself. They include natural laws and properties of materials.

Social limitations on the other hand are limitations that arise as a result of the society we are living in and include the ease of use, safety, attractiveness, and cost.

Explain the factors that affect the separation of mixtures in amino acids

Elenna [48]

Consider you have a mixture of amino acids(contains all set of amino acids such as polar, non polar). Other than TLC, how are you supposed to separate a single amino acid from the mixture without loss of amino acid quantitatively.

A cylinder with a movable piston originally has a volume of 2805 mL and is filled with nitrogen to a pressure of 4.00

Sergio039 [100]

This problem is providing the initial volume and pressure of nitrogen in a piston-cylinder system and asks for the final pressure it will have when the volume increases. At the end, the answer turns out to be 2.90 atm.

<h3>Boyle's law</h3>

In chemistry, gas laws are used so as to understand the volume-pressure-temperature-moles behavior in ideal gases and relate different pairs of variables.

In this case, we focus on the Boyle's law as an inversely proportional relationship between both pressure and volume at constant both temperature and moles:

$P_1V_1=P_2V_2$

Thus, we solve for the final pressure by dividing both sides by V2:

$P_2=\frac{P_1V_1}{V_2}$

Hence, we plug in both the initial pressure and volume and final volume in order to calculate the final pressure:

$P_2=\frac{2805mL*4.00atm}{3864mL}\\ \\P_2=2.90atm$
