Answer:
Balloon will burst
Explanation:
The amount of volume that can be held by the latex will reduce yet the volume of air inside does not change. therefore the air inside will force the latex to break.
Assume that you tie the balloon to prevent air from escaping and then squeeze the balloon with one hand, so there is less space inside it then balloon will burst.
What is latex balloon?
latex is what latex balloons are made of. Due to tiny microscopic holes in the latex, it is porous and does not hold helium for as long as foil balloons (mylar balloons).
While latex balloons usually float for only 8–24 hours, foil balloons typically float for 4–21 days. But you can actually get a latex balloon to float longer than a foil balloon by using a product called hi-float, which extends the life of a latex balloon by 25 times the average float time.
In addition to being available in a variety of colors and prints in sizes ranging from 5" to 3 feet, latex balloons can also be printed in many colors, however if you want a detailed design you really need to use foil balloons.
Therefore, Assume that you tie the balloon to prevent air from escaping and then squeeze the balloon with one hand, so there is less space inside it then balloon will burst.

The third residue contains a hydroxymethyl group side chain. The amino group of the first side chain binds to the unshown remainder of the peptide. The carboxyl group of the third side chain binds to the unshown remainder of the peptide. Determine which amino acids are present in the peptide.
Answer:
The peptide is composed of Alanine, Glycine and Serine and is written in shorthand as: Ala-Gly-Ser.
Explanation:
Amino acids contain an α-carboxyl group, an α-amino group, and an R side chain which distinguishes one amino acid from another.
Peptides are chains of amino acids which are covalently bonded together through substituted amide linkages known as peptide bonds. The reaction occurs between an amino group of one amino acid and the carboxyl group of another amino acid with the removal of a water molecule.
A tripeptide is a peptide composed of three amino acids linked together by peptide bonds.
In the given peptide, the first residue contains a methyl group side chain. The second residue contains a hydrogen atom side chain. The third residue contains a hydroxymethyl group side chain.
The amino acid that contains a methyl group side chain is Alanine (Ala).
The amino acid that contains a hydrogen atom side chain is Glycine, Gly.
The amino acid that contains a hydroxymethyl group side chain is Serine, Ser.
Therefore, the peptide is composed of Alanine, Glycine and Serine and is written in shorthand as: Ala-Gly-Ser.

A 1.00 L of a solution is prepared by dissolving 125.6 g of NaF in it. What would be the molarity of this solution?
Answer:
2.99 M
Explanation:
In order to solve this problem we need to keep in mind the definition of molarity:
Molarity = moles of solute / liters of solutionIn order to calculate the moles of solute, we convert 125.6 g of NaF into moles using its molar mass:
125.6 g NaF ÷ 42 g/mol = 2.99 mol NaFAs the volume is already given, we can proceed to calculate the molarity:
Molarity = 2.99 mol / 1.00 L = 2.99 MWhat is the apparent bond energy of a carbon–sulfur bond in cos?
This question is incomplete, the complete question is;
The enthalpy change for the reaction between two molecules of carbon oxysulfide (COS) to form one molecule of CO₂ and one molecule of CS₂, as shown below, is -3.2 x 10⁻²⁴ kJ per molecule of COS.
The bond energy for the C-S bond in C=S has been determined to be 552 kJ/mol.
What is the apparent bond energy of a carbon-sulfur bond in COS?
NOTE: A C=O bond adjacent to another double bond is not the same as a C=O bond that is not adjacent to another double bond.
Answer:
The apparent bond energy of a carbon–sulfur bond is 550.1 kJ/mole
Explanation:
Given the data in the question and the figure 8.122 in the image below;
the given reaction can be written as follows;
2COS -----→ CO₂ + CS₂
Δ[tex]H_{rxn}[/tex] = ∑ Bond Energy ( reactants) - ∑ Bond Energy (products)
= [ (2 × C=O) + (2 × C=S) ] - [ (2 × C=O) + ( 2 × C=S) ]
we know that;
Δ[tex]H_{rxn}[/tex] = -3.2 x 10⁻²⁴ kJ per molecule
= -3.2 x 10⁻²⁴ kJ × 2 × 6.023 × 10²³ kJ/mole
= -3.85 kJ/mole
Hence;
-3.85 kJ/mole = (2 × C=S)[tex]_{reactant}[/tex] - ( 2 × C=S)[tex]_{product}[/tex]
-3.85 kJ/mole = (2 × C=S)[tex]_{reactant}[/tex] - ( 2 × 552 kJ/mole)
(2 × C=S)[tex]_{reactant}[/tex] = -3.85 kJ/mole + 1104 kJ /mole
(2 × C=S)[tex]_{reactant}[/tex] = 1100.15 kJ/mole
2 × ( C=S)[tex]_{reactant}[/tex] = 1100.15 kJ/mole
( C=S)[tex]_{reactant}[/tex] = 1100.15 kJ/mole / 2
( C=S)[tex]_{reactant}[/tex] = 550.1 kJ/mole
Therefore, the apparent bond energy of a carbon–sulfur bond is 550.1 kJ/mole
The apparent bond energy of a carbon-sulfur bond in COS is equal to 550.08 kJ/mol.
Given the following data:
Enthalpy change of reaction = [tex]-3.2 \times 10^{-24}\;kJ/mol.[/tex]Bond energy of C=S = 552 kJ/mol.Scientific data:
Avogadro's number = [tex]6.02 \times 10^{23}[/tex]To determine the apparent bond energy of a carbon-sulfur bond in COS:
First of all, we would write a balanced chemical equation for the chemical reaction as follows:
[tex]2COS \rightarrow CO_2 + CS_2[/tex]
The enthalpy change of two (2) moles of COS is:
[tex]\Delta H_{rxn} = -3.2 \times 10^{-24}\times 2 \times 6.02 \times 10^{23}\\\\\Delta H_{rxn} =-3.85\;kJ/mol.[/tex]
Mathematically, the enthalpy change of a chemical reaction is given by this equation:
[tex]\Delta H_{rxn} = \sum Bond\;Energy_{(reactansts)} - \sum Bond\;Energy_{(products)}\\\\\Delta H_{rxn} = [(2\times C=O)+ (2\times C=S)]- [(2\times C=O)+ (2\times C=S)][/tex]
Substituting the parameters into the equation, we have;
[tex]-3.85 = (2\times C=S)- [2\times 552]\\\\(2\times C=S)=1104-3.85\\\\(2\times C=S)=1100.15\\\\(C=S)=\frac{1100.15}{2} \\\\(C=S)=550.08\;kJ/mol[/tex]
Therefore, the apparent bond energy of a carbon-sulfur bond in COS is equal to 550.08 kJ/mol.

Consider two compounds. Compound A contains 15.7 g of sulfur and 18.6 g of fluorine. Compound B contains 25.4 g of sulfur and 60.2 g of fluorine. For Compound A, the ratio of fluorine to sulfur is 1.18. For Compound B, the ratio of fluorine to sulfur is 2.37. Using the Law of Definite Proportions (also called the Law of Constant Composition), could Compound A and Compound B be the same compound
Answer:
No, compound A and B are not the same compound
Explanation:
According to the law of definite proportion "every chemical compound contains fixed and constant proportions (by mass) of its constituent elements." (Encyclopedia Britannica)
We can see in the question that the ratio of flourine to sulphur in compound A is 1.18 while the ratio of flourine to sulphur in compound B is 2.37.
The two chemical compounds do not contain a fixed proportion by mass of their constituent elements therefore, they can not be same compound according to the law of definite proportions.

What volume of sulfur dioxide, SO2 (at STP), is
produced by the burning of 0.250 mole of sulfur?
S(s) + O2(g) → SO2(g)
Answer:
5.6 L is the final volume for SO₂ at STP condtions
Explanation:
The reaction is: S(s) + O₂ (g) → SO₂ (g)
Ratio for this reaction is 1:1, if we see stoichiometry.
1 mol of sulfur can react to 1 mol of oxygen in orden to produce 1 mol of sulfur dioxide.
Then, 0.250 moles of sulfur can produce 0.250 moles of SO₂.
If we solve this by a rule of three, we can say:
At STP 1 mol occupies 22.4L
Then, 0.250 moles will be contained at (0.250 mol . 22.4L) /1mol = 5.6 L
If we apply the Ideal Gases Law:
P . V = n . R . T
1 atm . V = 0.250 mol . 0.082 . 273K
V = (0.250 mol . 0.082 . 273K) / 1atm → 5.6 L
