Layla is helping to clean car parts with a single chemical, but it isn't working. She washes her hands and tries a different chemical, which also does not work. She resumes with the first chemical without washing her hands. This time, the cleaning process works, but she begins to get dizzy and nauseated. What can Layla infer about the possible reason for her illness?

It is an acute effect of two toxins with a synergistic relationship.
It is a chronic effect of the second toxin she used to clean the parts.
The first chemical has an antagonistic relationship with the second.
The second chemical causes acute affects, and the first causes chronic affects.

Answers

Answer 1

Layla is helping to clean car parts with a single chemical, but it is not working. She washes her hands and tries a different chemical, which also does not work. She resumes with the first chemical without washing her hands. This time, the cleaning process works, but she begins to get dizzy and nauseated.

The first chemical is possibly toxic and may have caused Layla to become dizzy and nauseated when she resumed cleaning car parts without washing her hands after trying the second chemical. Layla could have accidentally ingested or absorbed some of the first chemical when she touched her mouth or rubbed her eyes while still contaminated with the chemical.A chronic effect is an effect that occurs as a result of exposure to a substance or substances over an extended period. The effect may not become evident until long after the exposure has occurred and may persist even after the exposure has ended. On the other hand, an acute effect is an effect that occurs soon after exposure to a substance or substances and usually lasts for a short period.The symptoms Layla experienced after resuming cleaning car parts with the first chemical are consistent with acute toxicity, which may cause symptoms such as dizziness, nausea, headache, skin irritation, and even death. Therefore, it is possible that the first chemical causes acute effects rather than chronic effects. However, the second chemical, which Layla washed her hands with, may also have toxic effects, but not necessarily acute ones.In conclusion, the fact that Layla experienced symptoms of dizziness and nausea after resuming cleaning car parts with the first chemical without washing her hands indicates that the chemical could be toxic and may have caused acute effects.

when you leave orange juice in the fridge for a while, the pope begins to sync to the bottom of the container. Why does this happen?

Answers

Orange Juice is a heterogeneous mixture. This means the orange juice contains more than one component.

This is true because orange juice contains two components. They are:

The juiceThe pulp

The reason why the pulp in orange juice sinks to the bottom is because the pulp is denser than the juice. So it is heavier and sinks to the bottom.

Density is how dense or heavy a substance is.  Orange juice is a mixture of pulp and juice.

When you leave orange juice in the fridge for a while, the pulp begins to sync and settle at the bottom and this is because the pulp is heavier or denser than the orange juice.

Calculate the molarity of each of the following solutions.
1.30 mol of KNO3 in 250.0 mL of solution
0.500 mol of BaCl2 in 100.0 mL of solution
0.195 mol of Na2CO3 in 200.0 mL of solution
7.00 mol of C6H12O6 in 250.0 mL of solution

Answers

Answer:

5.2M, 5M, 0.975M, 28M

Explanation:

M = ( moles × 1000 ) ÷ volume

Molarity is affected by temperature. Its unit is mole/litre. It measure the concentration of any solute in a solution. Thus the molarity of [tex]KNO_{3}[/tex],[tex]BaCl_{2}[/tex],[tex]Na_{2}CO_{3}[/tex] and[tex]C_{6}H_{12}O_{6}[/tex] are 5.2mol/litre, 5mol/litre, 0.97mol/litre, 28mol/litre respectively.

What is molarity?

Molarity can be calculated by dividing  number of moles of solute by volume of solution in liter.

Other concentration terms are molality, normality and mole fraction. Molarity can be used to find out the ionic strength of any solution

Mathematically,

Molarity= number of moles of solute/volume of solution in litre (1)

1) Molarity of [tex]KNO_{3}[/tex]= {1.30 mol ×(1000ml/l)}÷250.0 mL=5.2mol/litre

2)Molarity of [tex]BaCl_{2}[/tex]= {0.500 mol  ×(1000ml/l)}÷100.0 mL=5mol/litre

3)Molarity of[tex]Na_{2}CO_{3}[/tex]= {0.195 mol   ×(1000ml/l)}÷200.0 mL=0.97mol/litre

4)Molarity of [tex]C_{6}H_{12}O_{6}[/tex] = {7.00 mol  ×(1000ml/l)}÷ 250.0 mL=28mol/litre

Thus the molarity of [tex]KNO_{3}[/tex],[tex]BaCl_{2}[/tex],[tex]Na_{2}CO_{3}[/tex] and[tex]C_{6}H_{12}O_{6}[/tex] are 5.2mol/liter, 5mol/litre, 0.97mol/litre, 28mol/litre respectively.

What is emission spectrum ?

The electromagnetic radiation spectrum produced when an electron changes from a high energy state to a lower energy state is known as the emission spectrum of a chemical element or chemical compound.

The energy difference between the two states is equal to the photon energy of the emitted photon. Each atom contains a large number of potential electron transitions, and each transition has a distinct energy difference.

An emission spectrum is made up of a variety of transitions that result in various radiated wavelengths. The emission spectra of each element is distinct. Therefore, option d is correct.

The amount of K O H needed, in grams, in reaction 1 if you want to have 10% excess K O H

Answers

The mass of KOH reacted is 2.576 g. To have a 10% excess KOH, i need 2.833 g of KOH.

The equation of the reaction is;

2 Al(s) + 2 KOH(aq) + 6H20 (l) --------> 2K+ (aq) + 2 Al(OH)4^- (aq) + 3H2(g)

We are told that 1.25 g of Al was used in the reaction, hence;

Number of moles of Al = 1.25 g/27 g/mol = 0.046 moles

To obtain the amount of KOH required for the reaction;

2 moles of Al reacts with 2 moles of KOH

0.046 moles of Al also reacts with 0.046 moles of KOH

Mass of KOH reacted = 0.046 moles of KOH × 56 g/mol = 2.576 g

Himalayan pink salt has a density of 1.03 g/mL.

Calculate the volume, in liters (L), per kg of that salt.

Answers

The volume, in liters, per kg of the Himalayan pink salt would be 0.97 L

Recall that: density = mass/volume

Hence: volume = mass/density

In this case, the density of the Himalayan pink salt is 1.03 while the mass we are working with is 1 kg.

1 kg is equivalent to 1000 g

Thus: volume = 1000/1.03

                           = 970.87 mL

Divide by 1000 to convert to L

                        970.87/1000 = 0.97 L

Answer:

1)A moth bursting out of a cocoon is neither a chemical or physical change, it's a biological change.  If I had to chose it would be a physical change though.  Not to sure...

2)Playing with slime is a physical change.  

Explanation:

1)The reason why I would chose physical change is because the moth is changing it's physical state more than it's chemical composition, but you should say both if that's an option.  

2)A physical change is when the temperature, shape, or state of matter changes. A chemical change occurs when the actual substance changes.  An example of this is a chemical reaction.  Because the slime is changing shape and not substances, I would say that it's obviously a physical change.

Answers

The gas that is to be identified in the problem is C2H2

From the ideal gas equation;

PV = nRT

P = pressure of the gas = 745 torr or 0.98 atm

V = volume of the gas =  4.13 mL or 0.00413 L

n = number of moles of the gas = ?

R = gas constant = 0.082 atm Lmol-1K-1

T = temperature of the gas = 23°C + 273 = 296 K

n = PV/RT

n = 0.98 atm ×  0.00413 L/0.082 atm Lmol-1K-1 × 296 K

n = 0.00405/24.272

n = 0.000167 moles

Recall that;

Number of moles = mass/molar mass

molar mass = mass/Number of moles

molar mass = 0.00500-gram/0.000167 moles

molar mass = 30 g/mol

Since it is a hydrocarbon;

[12 +1]n = 30

n = 30/13

n = 2

What is the molarity of a solution that contains 114.4g NaCl (molar mass= 58.44 g/mol) in 1.2 L solution?

Answers

Answer:

1.6 M.

Explanation:

We want to find the molarity of a solution that contains 114.4 g NaCl in a 1.2 L solution.

Recall that molarity is given by:

[tex]\displaystyle \text{M} = \frac{\text{ mols solute}}{\text{ L soln.}}[/tex]

Convert 114.4 g NaCl to mol NaCl using its molecular weight:

[tex]\displaystyle 114.4 \text{ g NaCl} \cdot \frac{1 \text{ mol NaCl}}{58.44 \text{ g NaCl}} = 1.958\text{ mol NaCl}[/tex]

Therefore, the molarity of the solution will be:

[tex]\displaystyle \text{M} = \frac{1.958 \text{ mol NaCl}}{1.2\text{ L soln.}} = 1.6 \text{ M}[/tex]

In conclusion, the molarity of the solution is 1.6 M.
