Balanced chemical equation for the hydrogenation of glyceryl trilinolenate:
C₅₇H₉₂O₆ + 9H₂ → C₅₇H₁₁₀O₆.
Linolenic acid (octadecatrienoic acids ) is a type of fatty acid. It has 18 carbon atoms chain and three double bonds. So trilinolenate has nine double bonds.
Trilinolenate is the form of triglyceride esters of linolenic acid.
Hydrogenation is addition of hydrogen atoms at both sides of a double bond.
That question shoulda be true
Humans.
Humans have mass and take up space. :)
Hope this helps!
The average atomic mass of N2 is 14.0067. The atomic masses of the 2 stable isotopes of nitrogen, N-14 and N-15, are14.003074002 and 15.00010897 amu, respectively. Calculate the percent abundance of each nitrogen isotope. Ex.: The average atomic weight of copper is 63.5amu .
hope this helps!!!
In an average mass, each entry has equal weight. In a weighted average, we multiply each entry by a number representing its relative importance.
Assume that your class consists of 15 girls and 5 boys. Each girl has a mass of 54 kg, and each boy has a mass of 62 kg.
<em>Average mass</em> = (girl + boy)/2 = (54 kg + 62 kg)/2 = <em>58 kg</em>
<em>Weighted average (Method 1)
</em>
Use the <em>numbers of each</em> gender (15 girls + 5 boys)
,
Weighted average = (15×54 kg + 5×62 kg)/20 = (810 kg + 310 kg)/20
= 1120 kg/20 = <em>56 kg</em>.
If you put all the students on one giant balance, their total mass would be
1120 kg and the average mass of a student would be <em>56 kg.
</em>
<em>Weighted average (Method 2)
</em>
Use the <em>relative percentages</em> of each gender (75 % girls and 25 % boys).
Weighted average = 0.75×54 kg + 0.25×62 kg = 40.5 kg + 15.5 kg = <em>56 kg</em>
Each girl contributes 40.5 kg and each boy contributes 15.5 kg to the <em>weighted average</em> mass of a student.
