Reactions I and II are spontaneous reactions since they have negative delta G values.

Spontaneous reactions are reactions which proceed towards formation of products without addition of heat energy from the surroundings.

Spontaneous reactions have negative free energy change values (Delta G is negative) since the formation of products results in increase in entropy of the system.

Therefore, the spontaneous reactions are I and II because their delta G values are negative.

Answer:

Point A

Explanation:

The Northern Hemisphere is furthest away from the sun in position A. Therefore the sunlight takes longer to reach the Earth which results in the Northern Hemisphere experiencing winter.

Point A represents the position where the northern hemisphere is experiencing winter.

This is because Earth's axis is tilted away from the sun at this point, causing the northern hemisphere to receive less direct sunlight and shorter days. As a result, the rays from the sun are spread over a larger area, making the sunlight less intense and leading to colder temperatures during this time of the year in the northern hemisphere.

In contrast, at Point C, the northern hemisphere experiences summer. This is when the Earth's axis is tilted towards the sun, causing the northern hemisphere to receive more direct sunlight and longer days, resulting in warmer temperatures.

Points B and D are the equinox positions when the sun shines evenly on Earth from pole to pole, and both hemispheres experience approximately equal day and night lengths. These are the times of the year when transitions between seasons occur.

Considering the Hess's Law, the desired enthalpy is obtained through adding intermediate reactions together. (option D)

Hess's law, also called Law can also be called Law of additivity of the enthalpies of reaction, it is a useful method when it is not possible to calculate the enthalpies of reaction from the enthalpies of formation, or in reactions in which the reaction enthalpy cannot be determined experimentally because it is very slow or very explosive.

Hess's law states that when reactants are converted to products, the enthalpy change is the same whether the reaction takes place in one step or in a series of steps.

In this way, Hess's Law determines that when a chemical reaction can be expressed as an algebraic sum of other reactions, its reaction enthalpy is equal to the sum of the enthalpies of the partial reactions. In this way, it allows thermochemical equations to be treated as algebraic equations, and can be added, subtracted, or multiplied by a number to find the desired thermochemical equation.

Hess's Law states that the sum of the ∆H of each stage of the reaction will give us a value equal to the ∆H of the reaction when it occurs in a single stage.

That is, the desired enthalpy is obtained through adding intermediate reactions together. (option D)

Answer:What is the molarity of a solution made with 126.32 g of sodium hydroxide dissolved to make 874.2 mL of solution? answer. 3.612 M NaOH. 3.612 M NaOH.

Explanation:

Answer:

All objects can have the same size but have a different mass!

This is true, although it sounds fake. This is one example, there is a Neutron star, and Neutron stars are as big as a city, but they have a mass which is hundreds of times greater than our sun's mass. Because of them having so much mass, they are also having so much gravitational energy, which makes them also have gravity. They're so small, but have so much mass that they can do much. Even a drop of a neutron star can punch open the earth! It's true, so yes, it is possible for objects the SAME size to be having different masses according to that example.

But let's look on how they can have different mass.

They can have different masses becase of different densities. Put a iron ball inside water, and put an apple as close to the iron ball's side, what happens? The apple floats, becuase the apple's mass is less than the water, and the iron ball's mass is MORE than the water. So, because the iron ball is denser than the apple, that's why, it has more mass than the apple. The apple isn't much dense, it isn't as dense as water or the iron ball. But the iron ball is much more denser than the water. So because of the different material densities of the material, that's why it can have different masses.

Remember to Remember those 2 examples I gave you... (neutron star vs sun, iron ball vs apple on water)

The temperature at the air-conditioned house is 19° C. The temperature increases to 33° C in the beach. Molly's beach ball's volume will increase with increase in temperature.

Charles' law states that volume of gas increase with an increase in the temperature of the gas.

When pressure remain constant, if temperature increases, the volume of the ball will also increase.

Thus, Molly's beach ball's volume will increase with increase in temperature.

According to above statement, HCl ( Hydrochloric acid ) is a strong acid, which when mixed in water dissociates complete in water to form H+ and Cl- ions that means 100% dissociation. but acids weaker than HCl shows relatively less dissociation.

That is less than 100% dissociation when mixed in water ~

This information tells us about the relative dissociation of weaker acids is that weaker acids dissociates less than 100%.

Dissociation is defined as the breaking up of a compound into simpler constituents or components or parts. Ionic compounds dissociates in the water solution. Stronger acids have 100% ability to dissociate.

So we can conclude that this information tells us about the relative dissociation of weaker acids is that weaker acids dissociates less than 100%.

2,5,6-trimethyloctane

Explanation:

1) Count the number of carbons in the longest chain. If the structure contains a functional group (e.g. double bond, -OH), they have to be part of the chain that you're counting.

• The straight chain is the longest chain, and it contains 8 carbons

• Without the additional 3 methyl (-CH₃) substituents, it would be called octane (since it is an alkane)

2) Assign location numbers for the substituents, ensuring that they are the lowest possible numbers

• From left to right, we could name it as 2,5,6-trimethyloctane

• From right to left of the parent chain, it would be called 3,4,7-trimethyloctane

• Assigning from left to right gives us the lowest location numbers as the sum of the numbers is 13 instead of 14

• Remember to add 'tri' since we have 3 methyl groups

When a high amount of heat is supplied, the sugar melts faster than when a low amount of heat is supplied.

The term melting has to do with the breakdown of the bonds that hold the molecules of a substance together. Melting occurs when heat is applied continously to a body.

The heat produced when iron oxide reacts with carbon monoxide is -23.47 kJ/mol.

The standard enthalpy of the reaction is given by the enthalpy of formation of the products and the reactants. The reactants and the products of the reaction are:

Fe₂O₃ (s) + 3CO (g) → 2Fe(s) + 3CO₂ (g)

We know,

The standard enthalpy of formation of iron oxide = −825.50 kJ/mol

The standard enthalpy of formation of carbon monoxide = −110.53 kJ/mol

The standard enthalpy of formation of carbon dioxide = −393.52 kJ/mol

The standard enthalpy of reaction is calculated as:

[tex]\rm \Delta H_{rxn}[/tex] = [2(0) + 3(−393.52)] - [1(-825.50) + 3(-110.53)]

= (0−1180.56+825.50+331.59)

= −23.47 kJ/mol

Answer:

Cu (s)  and AlCl₃ (s)

Explanation:

This reaction can be classified as a single-displacement reaction, aka. a single-replacement reaction. These reactions involve one element swapping out another element in a compound. In this reaction, aluminum is taking the place of copper (ii) in the copper (ii) chloride compound. Aluminum takes the place of copper (ii) specifically because aluminum is more likely form a cation than anion. Copper (ii) serves as a cation in the compound.

Al (s) + CuCl₂ (s) --> Cu (s) + AlCl₃ (s)

The final products are copper (ii) metal and aluminum chloride. The metal of copper (ii) is produced instead of the cation in order to maintain the neutral charge balance of the reaction. The chorine has a subscript of 3 because aluminum usually forms cations of a +3 charge while chlorines form anions with a -1 charge.

The balanced equation is:

2 Al (s) + 3 CuCl₂ (s) --> 3 Cu (s) + 2 AlCl₃ (s)
