Answer:
[tex]\large \boxed{\text{6.21 L}}[/tex]
Explanation:
The temperature and amount of gas are constant, so we can use Boyle’s Law.
[tex]p_{1}V_{1} = p_{2}V_{2}[/tex]
Data:
[tex]\begin{array}{rcrrcl}p_{1}& =& \text{3.20 atm}\qquad & V_{1} &= & \text{2.00 L} \\p_{2}& =& \text{1.03 atm}\qquad & V_{2} &= & ?\\\end{array}[/tex]
Calculation:
[tex]\begin{array}{rcl}3.20 \times 2.00 & =& 1.03V_{2}\\6.40 & = & 1.03V_{2}\\V_{2} & = &\dfrac{6.40}{1.03}\\\\& = &\textbf{6.21 L}\\\end{array}\\\text{The new volume must be } \large \boxed{\textbf{6.21 L}}[/tex]
How does the pressure of a container change as the volume is changed?
Answer: If the volume is decreased, the pressure would increase because the gas molecules have less space to move around. Same goes for the opposite; if the volume increased, the pressure would decrease because the molecules have more space to move and aren't packed as tightly .

what two factors does elastic potential energy depend upon
Answer: Spring constant k as well as the distance stretched
Explanation:
Elastic potential energy is Potential energy stored as a result of deformation of an elastic object, such as the stretching of a spring. It is equal to the work done to stretch the spring, which depends upon the spring constant k as well as the distance stretched.

A 350. mL air sample collected at 35 degrees C has a pressure of 556 mm Hg.
What pressure will the air exert if it is allowed to expand to 425 mL at 57 degrees
C? Show your work in the space below.
Answer:
485 torr
Explanation:
Explanation:
We can solve this equation using the combined gas law:
P1V1/T1=P2V2/T2
Remember, always use the absolute (Kelvin) temperature when working with gas equations.
The temperature conversions are
T1=C+273=35o+273=308K
T2=57C+273=330K
Since we're trying to find the final pressure, let's rearrange this equation to solve for
P2:
P2=P1V1T2/T1V2
Our known values:
P1= 550 torr
V1=350mL
T1=308K
V2=425"mL
T2=330K
Let's plug these into the equation to find the final pressure:
The final pressure after it is subjected to these changes is thus 485torr
Why do we use nuclear energy from power plants?
Answer:
Nuclear energy originates from the splitting of uranium atoms – a process called fission. This generates heat to produce steam, which is used by a turbine generator to generate electricity. Because nuclear power plants do not burn fuel, they do not produce greenhouse gas emissions.

What type of bond is formed during dehydration synthesis?
O A
carbon bonds between amino acids
B.
carbon bonds between carbohydrates
C. hydrogen bonds between lipids
O D. peptide bonds between amino acids
A carbon bond between the amino acids is formed in a dehydration reaction. So the correct option is A.
What is a dehydration reaction?
A reaction where two smaller molecules are combined in a chemical manner by the removal of an element from each of these molecules is called a dehydration reaction. Organic compounds are classified on the basis of structure. They are classified as aliphatic and aromatic compounds. Different kinds of chemical reactions are involved in the formation of new compounds when there is a change in bonding between the atoms.
There are some chemical reactions that form a molecule and some only show a displacement or substitution of atoms. There are synthesis or combination reactions that involve a combination of two substances to form one molecule.
On the other hand, there are decomposition reactions in which one substance decomposes to form more than one substance. There are displacement reactions which can be single or double displacement. They involve the displacement of one or more components of compounds among each other. Addition, substitution, rearrangement, elimination, and oxidation-reduction reactions are some of the common organic reactions.
Therefore, the correct option is A.

can somebody help me name these organic compound plz
Answer:
A. 3–Ethyl–2–methylpentane.
B. 3–Ethyl–1,5,5–trimethylcyclohexene.
Explanation:
To name the compound, we must observe the following:
1. Locate the longest continuous carbon chain. This gives the parent name.
2. Identify the substituent groups attached.
3. Locate the position of the substituent groups by giving them the lowest possible low count alphabetically.
4. Combine the above to name the compound.
Now let us name the above compounds
For compound (A)
1.The longest chain is carbon 5 i.e pentane.
2. The substitute attached are:
Ethyl => CH2CH3
Methyl => CH3
3. Ethyl comes before methyl alphabetically. But considering the structure of the compound, ethyl assume same position from either side of the compound. Therefore, we'll consider the lowest possible count for methyl. Therefore, their position is given below:
Ethyl => CH2CH3 => carbon 3.
Methyl => CH3 => carbon 2.
4. The name of the compound is:
3–Ethyl–2–methylpentane.
Compound B.
This is a cyclic structure.
1. The parent name is cyclohexene.
2. The substitute groups attached are:
Ethyl => CH2CH3
Methyl => CH3
3. Since the compound is unsaturated, the functional group is the double bond. Hence, we shall start our counting from the double bond and also considering alphabetical order of the substituent.
Please note methyl (CH3) appears three times.
Ethyl => CH2CH3 => carbon 3
Methyl => CH3 => carbon 1, 5 and 5.
4. The name of the compound is:
3–Ethyl–1,5,5–trimethylcyclohexene

A student determines that she used 0.0665 mol of sodium hydroxide (NaOH) to completely titrate 25.00 mL of sulfuric acid solution (H2SO4). What is the molarity of the sulfuric acid?
0.00131 M
0.00262 M
1.31 M
2.62 M
A student determines that she used 0.0665 mole of sodium hydroxide (NaOH) to completely titrate 25.00 mL of sulfuric acid solution. The molarity of the sulfuric acid is 1.31 M. Therefore, option C is correct.
What is molarity?Number of moles of solute per liter of solution is known as molarity.
The balanced chemical equation for the reaction between sodium hydroxide and sulfuric acid is:
2 NaOH + H₂SO₄ → Na₂SO₄ + 2 H₂O
According to the balanced equation, one mole of sulfuric acid reacts with two moles of sodium hydroxide. Therefore, the number of moles of sulfuric acid in the titrated solution can be calculated as:
moles of H₂SO₄ = (moles of NaOH) / 2
moles of H₂SO₄ = 0.0665 mol / 2
moles of H₂SO₄ = 0.03325 mol
The volume of the sulfuric acid solution used in the titration is 25.00 mL, which is equivalent to 0.02500 L. The molarity (M) of the sulfuric acid can be calculated as:
Molarity of H₂SO₄ = moles of H₂SO₄ / volume of H₂SO₄ solution in liters
= 0.03325 mole / 0.02500 L
= 1.31 M
Thus, option C is correct.
