D.) Edmond Locard. He formulated the basic principle that there will be a transfer of material if one object touches another. This material may contaminate a specimen and make it useless as forensic evidence.
“A.) Leone Lattes” is <em>incorrect</em>. He developed a method for <em>blood typing</em> that relied on detection of the specific antibodies.
“B.) Mathieu Orfila” is <em>incorrect</em>. He worked to make <em>chemical analysis</em> a routine part of forensics.
“C.) Hsi Duan Yu” is <em>incorrect</em>. It is a 13th century Chinese <em>book </em>that many people consider to be the first known guide to forensic pathology.
1. The world without boron would be like a "turtle hiding inside it's shell" Almost everything that we need biologically would not be supplied. There would be plant disorder because of lack of boron that is needed for plants growth. And it would be widespread around the world and causes large of scarcity of food production resulting to chain of reaction to other factors that is part of our daily lives. We are not that high-tech as now and the transition of technology would not be as what we would be expecting in the years to come. We may obtain some of it naturally but it would not be enough later on as the population keeps on growing.
2. Life is still life because we still have other resources we need but it would be quite different as Boron plays a vital role since the earth's formation. As it has many uses in the beginning of civilization as we relies on borates for almost everything. Probably, widespread of plant disorder, poor production of food, rampant of sickness may happen, increasing of pestilence that some of the key ingredient of household products relies on it.
Hello!
An amino acid has five basic parts. An amino group, a carboxyl group, a central carbon atom, a hydrogen, and a R group.
The r group is the side chain specific to each amino acid. The r group varies between each kind of amino acid, while everything else stays the same. Therefore, the r group decides the identity of the amino acid.
Hope this helps! Let me know if you need a more specific explanation.
4. (1)/[1(12)+4(1)] = <u>25% </u>
I'm pretty sure this is your answer.
<h3>If you need to see this solved easier, no worries! =</h3>
4. 4 / 16 = <u>25%</u>
<em>I hope this helped! Good luck.</em>
The theoretical yield of BaCO3 is 5.5
<h3>What is theoretical yield?</h3>
The theoretical yield is the yield calculated from the stoichiometry of the reaction. The equation of the reaction is;
Ba(NO3)2(aq) + Na2CO3 (aq) ------> BaCO3(s) + 2NaNO3(aq)
Number of moles of limiting reactant: 0.4 M × 70/1000 = 0.028 moles
Since the reaction is 1:1,om;y 1 mole of BaCO3 is formed. Hence, mass of BaCO3 = 0.028 moles × 197 g/mol = 5.5g
