Synthetic fibers, like plastic, are derived from organic compounds. These fibers have been chemically changed by humans to last longer for better storage and more effective uses. These fibers are stronger than naturally occurring fibers like cotton and wool. Which of the following is a downside to these synthetic fibers when compared to natural fibers?
A.
The longer lasting material is more difficult to break down.
B.
The longer lasting material is less useful in manufacturing.
C.
The longer lasting material is not able to withstand high temperatures.
D.
The longer lasting material makes the fibers more expensive to buy.

Answers

Answer 1

The downside of this is that the longer lasting material is more difficult to break down.

Both natural fibers and synthetic fibers are polymer materials. Polymer materials are materials that are made by the agglomeration of small molecules called monomers.

The natural fibers are less long lasting than the synthetic fibers. The downside of this is that the longer lasting material is more difficult to break down. As a result of these, synthetic fibers lead to environmental pollution problems.

When under a pressure of 9.5 atm, a piston has a volume of 1.7 liters. It the piston is compressed to a
volume of 1.1 liters, what will the new pressure be?
c. 8.90 atm
a. 5.08 atm
b. 6.15 atm
d. 14.7 atm

Answers

Answer:

D

Explanation:

according to boyle's law the temperature and pressure of a gas are inversely proportional given by the equation

p1v1=p2v2

In this case p1 is 9.5,v1 is 1.7,v2 is 1.1 and we have to find p2

9.5×1.7=p2×1.1

16.15/11=1.1p2/1.2

p2=14.7

I hope this helps

Answer:

[tex]\boxed {\boxed {\sf D.\ 14.7 \ atm}}[/tex]

Explanation:

We are asked to find the pressure on a gas given a change in volume. We will use Boyle's Law which states the volume of a gas is inversely proportional to the pressure. The formula for this law is:

[tex]P_1V_1=P_2V_2[/tex]

The gas originally has a pressure of 9.5 atmospheres and a volume of 1.7 liters.

[tex]9.5 \ atm * 1.7 \ L = P_2V_2[/tex]

The gas is compressed to a volume of 1.1 liters, but the pressure is unknown.

[tex]9.5 \ atm * 1.7 \ L = P_2* 1.1 \ L[/tex]

We want to find the new pressure, so we must isolate the variable P₂. It is being multiplied by 1.1 liters. The inverse operation of multiplication is division. Divide both sides of the equation by 1.1 L.

[tex]\frac {9.5 \ atm * 1.7 \ L}{1.1 \ L} =\frac{ P_2* 1.1 \ L}{1.1 \ L}[/tex]

[tex]\frac {9.5 \ atm * 1.7 \ L}{1.1 \ L} =P_2[/tex]

The units of liters cancel.

[tex]\frac {9.5 \ atm * 1.7 }{1.1 } =P_2[/tex]

[tex]\frac {16.15}{1.1} \ atm =P_2[/tex]

[tex]14.6818181818 \ atm= P_2[/tex]

Round to the tenths place. The 8 in the hundredth place tells us to round the 6 up to a 7.

[tex]14.7 \ atm \approx P_2[/tex]

The new pressure at a volume of 1.1 liters is approximately 14.7 atmospheres.

A gas occupies 210 mL at -73°C to have the same gas occupy 360 mL:
should the temperature be increased or decreased?
what is the new temperature? __ K

Answers

Answer:

a. The temperature should be increased.

b. 342.86K

Explanation:

Using Charles law equation as follows:

V1/T1 = V2/T2

Where;

V1 = initial volume (mL)

V2 = final volume (mL)

T1 = initial temperature (K)

T2 = final temperature (K)

According to this question, the following information were given:

V1 = 210mL

V2 = 360mL

T1 = -73°C (-73 + 273 = 200K)

T2 = ?

Using V1/T1 = V2/T2

210/200 = 360/T2

Cross multiply

200 × 360 = 210 × T2

72000 = 210T2

T2 = 72000/210

T2 (new temperature) = 342.86K

Is lithium (Li) more or less reactive than beryllium (Be)? Why?

Answers

Answer:

Below!

Explanation:

Lithium (Li) is more reactive than Beryllium (Be). This is because Lithium lacks the valence electron that Beryllium has. Elements with a lower amount of valence electrons are less stable than those with full valence shells, causing it to react more easily. Because Lithium only contains 1 valence electron, it is easily transferred/given up to create bonds and form compounds.

Hope this helps ya! Best of luck <3

Compared to beryllium, lithium (Li) is much more reactive (Be). This is due to Lithium's lack of Beryllium's valence electron.

What is chemical reactivity?

Reactivity in chemistry is a gauge of the ease with which a substance reacts chemically. The chemical may react independently or in combination with other atoms and compounds, and in either case, energy will typically be released. The most reactive substances and elements have the potential to spontaneously or explosively ignite.

They typically ignite when exposed to oxygen in the atmosphere and water. Reactivity is temperature-dependent. The available energy for just a chemical reaction increases with temperature, often increasing its likelihood. The noble gases are the least reactive elements. Hydrogen is the least active catalyst in this group and doesn't produce any stable compounds. Compared to beryllium, lithium (Li) is much more reactive (Be). This is due to Lithium's lack of Beryllium's valence electron.

Therefore, compared to beryllium, lithium (Li) is much more reactive (Be). This is due to Lithium's lack of Beryllium's valence electron.

Which of the following would tell you that a weak base is present?

A. An indicator added to the solution turns green-blue.
B. If there is a high reaction rate.
C. If the pH of the solution is close to 14.
D. If the solution is a good conductor of electricity.

Answers

Answer:

A. An indicator added to the solution turns green-blue.

Explanation:

A pH scale measures the concentration of hydrogen ions in acidic and alkaline solutions.

In chemistry, pH literally means the power of hydrogen ions and it is a measure of the molar concentration of hydrogen ions in a particular solution; thus, specifying the acidity, neutrality or basicity of any chemical solution.

Mathematically, the pH of a solution is given by the formula;

[tex] pH = -log_{10}(H^{+}) [/tex]

On a pH scale, a solution with a pH of 7 is neutral, a solution with a pH below 7 is acidic and it's basic (alkaline) when it's pH is above 7.

A pH indicator can be defined as a compound (substance) that indicates the concentration of hydrogen ions present in a solution by changing its color over a narrow range of pH values.

A pH range of 1 to 3 (1 - 3) represents a strong acid with a red color.

When an indicator added to a solution turns green-blue, it simply means that a weak base is present.

Answer:

The current of the toaster is 3.93A

Explanation:

Using the GRASS method:

G: Given: The information that is given is that we have 28Ω of Resistance and 110V of voltage.

R: Required: We need to find the current measured.

A: Action: We can use Ohm's law that relates resistance, voltage and current in the equation:

V = R*I

Or:

I = V/R

Where I is current in A, V is voltage = 110V and R is resistance = 28Ω

An aqueous solution contains
32.7% KCl (weight/weight %).

How many grams of water (H20) are contained in 100 g of this solution?

Answers

Answer:

67.3g

Explanation:

%(w/w) = mass of solute/total mass of solution × 100

According to this question, an aqueous solution contains 32.7% KCl (w/w%). Firstly, we find the mass of the solute (KCl) as follows, if the mass of solution is 100g:

32.7 = mass of solute/100 × 100

mass of solute (KCl) = 32.7g

Mass of solution = mass of solvent (water) + mass of solute (KCl)

100g = x + 32.7g

x = 100 - 32.7

x = 67.3

Hence, the mass of water contained in the 100g solution is 67.3g.

What is the quantity of carbon-14 in a bone after 17,190 years if the initial mass of C-14 is 0.300 grams and the half-life is 5,730 years?

A.
0.038 g
B.
0.093 g
C.
0.281 g
D.
0.412 g

Answers

A. 0.038 g.

Explanation:

The decay of carbon-14 is a first order reaction.

The rate constant of the reaction (k) in a first order reaction = ln (2)/half-life = 0.693/(5730 year) = 1.21 x 10⁻⁴ year⁻¹.

The integration law of a first order reaction is:

kt = ln [Ao]/[A]

k is the rate constant = 1.21 x 10⁻⁴ year⁻¹.

t is the time = 17,190 years.

[Ao] is the initial concentration of carbon-14 = 0.300 g.

[A] is the remaining concentration of carbon-14 = ??? g.

∵ kt = ln [Ao]/[A]

∴ (1.21 x 10⁻⁴ year⁻¹)(17,190 years) = ln (0.300 g)/[A]

2.08 = ln (0.300 g)/[A]

Taking exponential for both sides:

8.0 = (0.300 g)/[A]

∴ [A] = 0.0375 g ≅ 0.038 g
