Hello!
Standards of mass are necessary because it is a whole lot easier than using a bunch of different systems. Since the metric system is common, it would be easier to compare something with someone from America and someone from Germany using the metric system as opposed to something otherwise.<span />
Answer:
Nitrogen thet cannot be used by organisms. C.
Explanation:
Free nitrogen is simply molecular nitrogen (N2). Nitrogen, in its molecular form, consists of two nitrogen atoms bound together with a tripple bond. Because it is very stable, N2 is typically nonreactive, and takes a lot of energy to break them apart. Among these are the amino acids necessary for life to begin and which are the building blocks DNA is made from. Basically, any nitrogen that is in an organic compound is considered “fixed” nitrogen and N2 is considered to be “free” nitrogen
Answer:
The answer to your question is V2 = 0.92 l
Explanation:
Data
Volume 1 = V1 = 2.4 l
Pressure 1 = P1 = 1.5 atm
Temperature 1 = T1 = 273 °C
Volume 2 = V2 = ?
Pressure 2 = 4.5 atm
Temperature 2 = 313 °K
Process
To solve this problem use the Combined gas law
P1V1/T1 = P2V2/T2
-Solve for V2
V2 = P1V1T2 / T1P2
-Substitution
V2 = (1.5 x 2.4 x 313) / (273 x 4.5)
-Simplification
V2 = 1126.8 / 1228.5
-Result
V2 = 0.92 l
Explanation:
<em>Punnett squares can determine the likelihood of producing a child with a particular trait. Two individuals who know their genotype for the trait, using a Punnett square allows them to visualize the potential genotypes of their offspring as well as determine the likelihood of trait expression.</em>
