The effect of energy in phase transitions of matter is that it is required to break the intermolecular forces that hold the particles of a substance together. When energy is added to a substance, the particles move faster and the intermolecular forces are broken. This can cause the substance to change phase.

The interactive demonstration on the sample of water shows that energy is required to melt ice and boil water. When the ice is heated, the particles start to move faster and the ice melts. The temperature of the water stays constant at 0°C until all of the ice has melted. This is because the energy is being used to break the intermolecular forces in the ice. Once all of the ice has melted, the temperature of the water starts to rise again. When the water is boiled, the particles move so fast that they escape from the liquid state and become a gas. The temperature of the water stays constant at 100°C until all of the water has boiled. This is because the energy is being used to break the intermolecular forces in the water. Once all of the water has boiled, the temperature of the steam starts to rise again.

Heating curves show the temperature of a substance as it is heated. The curve has a horizontal line at the melting and boiling points, which indicates that the temperature does not change during these phase changes.

Cooling curves show the temperature of a substance as it is cooled. The curve has a horizontal line at the melting and boiling points, which indicates that the temperature does not change during these phase changes.

Both curves show that the temperature of a substance increases as it is heated and decreases as it is cooled.

A heating curve is more choppy than a cooling curve because there are more phase changes during heating than during cooling.

Here, we want to select the most important information piece to determine saturation

The best way to check for this is to check the kind of bonds between the carbon atoms in the molecule

We need 2.77 liters of hydrogen gas to react with 9.0 g of bromine.



From this equation, we can see that 1 mole of hydrogen gas (H2) reacts with 1 mole of bromine (Br2) to produce 2 moles of hydrogen bromide (HBr).
we need to use the molar mass of bromine, which is 79.9 g/mol.
Number of moles of Br2 = mass / molar mass = 9.0 g / 79.9 g/mol = 0.113 moles
Since 1 mole of H2 reacts with 1 mole of Br2, we need 0.113 moles of H2 to react with the given amount of Br2.
To find out how many liters of H2 are needed, we need to use the ideal gas law, which relates the number of moles of a gas to its volume:

PV = nRT

where P is the pressure of the gas (in atm), V is the volume (in liters), n is the number of moles, R is the gas constant (0.0821 L·atm/mol·K), and T is the temperature (in Kelvin).

Assuming standard conditions of temperature and pressure (STP), which are 0°C (273 K) and 1 atm, respectively, we can simplify the equation to:
V = nRT/P = (0.113 mol)(0.0821 L·atm/mol·K)(273 K)/(1 atm) = 2.77 L

The temperature at which the reaction would go twice as fast is 62.2 °C. The rate constant at a temperature of 110 °C would be 3.89 s^-1.

Let's use the Arrhenius equation to solve the problem:

k = Ae^(-Ea/RT)

where k is the rate constant, A is the pre-exponential factor, Ea is the activation energy, R is the gas constant, and T is the temperature in Kelvin.

Part A:

We have k1 = 0.0190 s^-1 at T1 = 29°C = 302 K, and we want to find T2 such that k2 = 2k1.

First, let's find A:

k1 = Ae^(-Ea/RT1)

A = k1 / e^(-Ea/RT1)

Then, let's find T2:

k2 = 2k1 = 2Ae^(-Ea/RT2)

e^(-Ea/RT2) = k2/2A

ln(e^(-Ea/RT2)) = ln(k2/2A)

-Ea/RT2 = ln(k2/2A)

T2 = -Ea/(R*ln(k2/2A))

Plugging in the values, we get T2 = 62.2 °C.

Part B:

We have k1 = 0.0190 s^-1 at T1 = 29°C = 302 K, and we want to find k2 at T2 = 110°C = 383 K.

Using the Arrhenius equation, we have:

k1/k2 = e^(Ea/R)(1/T2 - 1/T1)

k2 = k1 * e^(Ea/R)(1/T2 - 1/T1)

Plugging in the values, we get k2 = 3.89 s^-1.

Atoms share electrons with each other to form covalent bonds. Covalent bond is a kind of chemical bond in which atoms share electrons to obtain a stable electron configuration.

Atoms share electrons with each other to form covalent bonds. This kind of bonding is the sharing of electrons between atoms so that both atoms are able to gain a full outer shell of electrons.

The sharing of electrons is equal in the formation of covalent bonds, as both atoms are able to share electrons to get closer to having a complete shell of valence electrons.

There are two types of covalent bonds: polar and non-polar. A non-polar covalent bond takes place when the electrons are shared equally between the two atoms. A polar covalent bond occurs when electrons are unequally shared between the two atoms, resulting in a small charge on the molecule's electronegative end.

Polarity in covalent bonds is determined by the electronegativity difference between the two atoms. If the difference is 0.4 or more, the bond is considered polar, and if it is less than 0.4, it is considered non-polar.

For example, a bond between carbon and hydrogen is non-polar since the difference in electronegativity is small.

A bond between hydrogen and oxygen is polar because oxygen is more electronegative than hydrogen, so the electrons are more strongly drawn to the oxygen atom.

A reducing chemical reaction adds an electron to the substrate.

Reduction is a term used to describe the yield of electrons, the accumulation of hydrogen, or the reduction of oxygen from the substrate.

When a reactant accumulates electrons during a reaction, it is called reduction. Reduction reactions include the addition of electrons to a substrate and the donor of the electrons is a reducing agent that itself brings oxidization. Therefore a reducing chemical reaction retains the addition of electrons to a substrate.

Oxidation-reduction (redox) reactions consist of the transfer of electrons between compounds while catabolic reactions are the type of reactions in which complex substances are split down into simpler units with the discharge of energy. Therefore these options are incorrect

There are approximately 0.000486 moles of hydrogen present in the sample.

To find the number of moles of hydrogen present in the sample, you need to use the ideal gas law equation, which is PV = nRT where P is the pressure of the gas (in atm), V is the volume of the gas (in L), n is the number of moles of gas, R is the ideal gas constant, and T is the temperature of the gas (in K). First, you need to convert the pressure from torr to atm. You can do this by dividing the pressure in torr by 760, since 1 atm is equal to 760 torr. In this case, the pressure in atm would be: P = 764.5 torr / 760 = 1.0059 atm Next, you need to convert the volume from ml to L. You can do this by dividing the volume in ml by 1000, since 1 L is equal to 1000 ml. In this case, the volume in L would be: V = 30.42 ml / 1000 = 0.03042 L Finally, you need to convert the temperature from degrees Celsius to Kelvin. You can do this by adding 273.15 to the temperature in Celsius. In this case, the temperature in K would be:T = 25.58 degrees Celsius + 273.15 = 298.73 K Now that you have all the necessary values, you can plug them into the ideal gas law equation to solve for the number of moles of hydrogen: n = (PV) / (RT) = (1.0059 atm * 0.03042 L) / (8.31 J/mol*K * 298.73 K) = 4.86 x 10^-4 mol Therefore, there are approximately 0.000486 moles of hydrogen present in the sample

All the rest is Chemical Change

The most likely tripeptide to be soluble in a hydrophobic solvent like benzene is option (c) N - proline - phenylalanine - leucine - C.

This is because all three amino acids in this tripeptide possess hydrophobic side chains. Proline has a unique cyclic structure, while phenylalanine and leucine have large, nonpolar side chains. These characteristics make the tripeptide more compatible with organic solvents, as they promote hydrophobic interactions.

In contrast, the other tripeptides contain amino acids with polar or charged side chains, making them less likely to be soluble in a hydrophobic solvent. For example, options (b) and (d) have lysine and arginine, which are positively charged, and options (e) and (d) have glutamate and aspartate, which are negatively charged. These charged amino acids will preferentially interact with polar solvents like water, reducing their solubility in benzene.
