3. How can a forensic palynologist help a crime investigation?
4. What are the challenges of using a forensic palynologist in crime investigations?
Answer:
A forensic palynologist is a spore and pollen expert that helps solve crimes.
The case that Mildenhall worked on was about a murder that involved a prostitute. The police couldn’t find a trace to help solve the case, so they called Mildenhall to help with pollen clues. He was able to find trace evidence in the pollen, which helped police connect the victim to a gang hangout by the crime scene.
A forensic palynologist can help with a criminal investigation by comparing pollen from the suspect and the victim using a comparison microscope to determine if the pollen matches.
The challenges of using a forensic palynologist in a criminal investigation are that judges and juries may have a hard time understanding palynologists.
Explanation:

What is it called when instead of getting rid of a product you find another
use for the product?
Answer:
Recycling.
Explanation:
When instead of getting rid of a product you find another use for the product, it is called recycling.
Recycling can be defined as a process which typically involves gathering, processing and transformation of materials or products that would otherwise be gotten rid of as waste materials or trash into new products that could be used for another purpose.
Basically, the recycling process involves turning a trash or unwanted product into a treasure (new product) that is capable of serving another purpose.
For example, the crown cork of a bottle could be gathered and processed into art forms that can be used for decorations.
A sample of NH3(g) is placed in a rigid container. When the equilibrium below is established, the partial pressure of hydrogen gas is 0.978 atm. What is the partial pressure of N2(g) at equilibrium?
Answer:
PpN₂ = 0.326 atm
Explanation:
In this case, let's write the equilibrium reaction taking place here:
2NH₃(g) <------> 3H₂(g) + N₂(g)
Now, we know that when the reaction reach the equilibrium the partial pressure of H₂ is 0.978 atm, so, let's write an ICE chart and see what's happening here:
2NH₃(g) <------> 3H₂(g) + N₂(g)
i) y 0 0
c) -2x +3x x
e) y-2x 3x x
At the beggining we just have the sample of NH₃, we don't know how much but we don't need that data to get the partial pressure. In equilibrium, its produced hydrogen and nitrogen, and we know how much of hydrogen was produced, so, with that we can solve for the value of the partial pressure of NO by a simple math operation:
PpH₂ = 0.978 atm = 3x
PpN₂ = x
PpN₂ = PpH₂ / 3
PpN₂ = 0.978 / 3
PpN₂ = 0.326 atmHope this helps

Starting with 5.00 g barium chloride n hydrate yields 4.26 g of anhydrous barium chloride after heating. Determine the integer n.
Answer:
BaCl₂·(H₂O)₂
Explanation:
The reaction that takes place is:
BaCl₂·(H₂O)ₙ → BaCl₂ + nH₂OThe information given by the problem tells us that 5.00 g of reactant were consumed. Of those 5.00 g, 4.26 g were converted into BaCl₂, this means that the other 0.74 g were converted into water.
We convert 0.74 g of water into moles, using its molar mass:
0.74 g H₂O ÷ 18 g/mol = 0.041 mol H₂OThen we convert 4.26 g of BaCl₂ into moles:
4.26 g BaCl₂ ÷ 208.23 g/mol = 0.0204 mol BaCl₂We can write these results as (BaCl₂)₀.₀₂·(H₂O)₀.₀₄. We multiply those coefficients by 50 in order to make them integers, and we're left with:
BaCl₂·(H₂O)₂2. Which of the following could the flame test be used for?
A sample of 0.600 mol of a metal M reacts completely with excess fluorine to form 46.8 g of MF2.?
a) How many moles of F are in the sample of MF2 that forms? (1.20 mol F)
b) How many grams of M are in this sample of MF2?
c) What element is represented by the symbol M? (Ca)
Answer:
See Explanation
Explanation:
Given:
moles M = 0.600 mole
moles F = excess (for rxn stoichiometry)
Formula Weight (F.Wt.) of F = 19 grams/mole (from Periodic Table)
Yield in grams = 46.8 grams (assuming theoritical yield)
Rxn: M + F₂ => MF₂
0.600mol Excess 0.600mol (1:1 rxn ratio for M:MF₂)
a. moles of F in MF₂ = 2(0.600) moles F = 1.2 moles F
b. mole weight MF₂ = 46.8g/0.600mol = 78g/mole
F.Wt. MF₂ = F.Wt. M + 2(F.Wt. F)
=> mass M = F.Wt. M = [F.Wt. MF₂ - 2(F.Wt. F)] = 78g/mol. - 2(19g/mol.)
= (78 - 38) grams/mole = 40 grams/mole
c. Calcium (Ca) has F.Wt. = 40 grams/mole (compared to Calcium on Periodic Table.
From the question, the metal is the limiting reactant and must be used to obtain the required results which are;
a) There are 1.20 mol F in MF2.
b) There are 40g of M in MF2.
c) M is calcium.
From the reaction equation;
M + F2 ----> MF2
Since the reaction is 1:1, 0.600 mol of MF2 is formed
Note that 1 mole of MF2 contains two moles of F and one mole of M
Hence, number of moles of F in MF2 = 2 * 0.600 mol = 1.20 mol F
Since 1 mole of M is contained in MF2, there are 0.600 moles of M in MF2.
If 1 mol of M forms 1 mole of MF2
And, 0.600 mol of M form 0.600 mol of MF2
Number of moles of MF2 = mass/molar mass
Number of moles of MF2 = 0.600 mol
Mass of MF2 formed = 46.8 g
Molar mass of MF2 = mass/Number of moles of MF2
Molar mass of MF2 = 46.8 g/0.600 mol
Molar mass of MF2 = 78 g/mol
Molar mass = Sum of Relative atomic mass of component atoms.
Hence;
78 = M + 2(19)
M = 78 - 2(19)
M = 40 g
The element must be calcium

The breakdown of a certain pollutant X in sunlight is known to follow first-order kinetics. An atmospheric scientist studying the process fills a 20.0Lreaction flask with a sample of urban air and finds that the partial pressure of X in the flask decreases from 0.473atm to 0.376atm over 5.6hours.
Calculate the initial rate of decomposition of X, that is, the rate at which Xwas disappearing at the start of the experiment.
Round your answer to 2 significant digits.
Answer:
0.019 atm / hr
Explanation:
Initial Concentration (Pressure) [A]o = 0.473 atm
Final Concentration (Pressure) [A] = 0.376 atm
Time = 5.6 hours
The breakdown follows first order kinetics.
The integrated rate law for a first order reaction is given as;
ln[A] = ln[A]o - kt
ln(0.376) = ln(0.473) - k (5.6)
ln(0.376) - ln(0.473) = - 5.6 k
5.6 k = 0.23
k = 0.0411 hr⁻¹
The rate of decomposition is given as;
Rate = k [X]
Where [X] represents Concentration (Pressure) = 0.473 atm
Rate = 0.0411 * 0.473 = 0.019 atm / hr

Determine the empirical and molecular formulas of the mandelic acid
Answer:
Both empirical and molecular are C₈H₈O₃.
Explanation:
Hello!
In this case, according the attached picture, it is possible to figure out the molecular formula of the mandelic acid by counting each carbon, hydrogen and oxygen in the molecule.
In such a way, we can see the presence of eight carbon atoms, eight hydrogen atoms and three carbon atoms; thus, the molecular formula is:
C₈H₈O₃
Furthermore, since the empirical formula is the smallest representation of the molecular formula when we are able to simplify it, we evidence no simplification is possible, consequently, the empirical formula equals the molecular one.

Aqueous solutions of ionic compounds cause to dissociate, hence, ions are free to conduct electricity
Explanation:
Ionic compounds are compounds formed from ions (charged atoms). For example, NaCl is an ionic compound from the following ions; Na+ (cation) and Cl- (anion). One characteristics of ionic compounds is their ability to dissociate into the ions that form them when in an aqueous solution i.e. NaCl will dissociate into Na+ and Cl- when in an aqueous solution.
These disssociated ions are free to conduct electricity, hence, making ionic compounds good conductors of electricity.

A student connects a battery to a wire and wraps the wire around an iron nail to produce an electromagnet. Which action
should the student take to increase the number of paper clips the electromagnet can pick up?
He should replace the iron nail with a plastic spoon.
He should add another battery.
He should decrease the current through the wire
He should reduce the number of turns
Answer:
He should add another battery.
Explanation:
An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire wound into a core of magnetic material usually an iron core. When an electric current-producing battery is connected to the wire, an electric current will begin to flow and the iron core will become magnetized. When the battery is disconnected, the iron core will lose its magnetism.
Electromagnets works based on the electromagnetic field which is a field force due to the interaction of the electric and magnetic fields. the force on the wire is proportional to the size of the current, the length and thickness of the iron core, as well as the number of turns of wire around the iron core.
Therefore, from the number of possible action given that the student can take in order to increase the magnetism of his electromagnet, adding another battery, thereby increasing the current will be the best way to increase the number of paper clips tat his electromagnet can pick up.

What are conductors?Conduction is defined as a process as a means of which heat is transferred from the hotter end of the body to it's cooler end.Heat flows spontaneously from a body which is hot to a body which is cold. Substances which enable conduction are called conductors.Conductors allow passage heat and electricity through the material.
In the process of conduction,heat flow is within the body and through itself.In solids the conduction of heat is due to the vibrations and collisions of molecules while in liquids and gases it is due to the random motion of the molecules .
When conduction takes place, heat is usually transferred from one molecule to another as they are in direct contact with each other.There are 2 types of conduction:1) steady state conduction 2) transient conduction.According to the type of energy conduction is of three types:
