Aldohexose is a monosaccharide with six carbon atoms and an aldehyde functional group. It contains multiple chiral centers, which are carbon atoms bonded to four different groups. To determine the number of chiral carbons, we must count the number of hydroxyl groups or hydrogen atoms.so, correct answer is b) four

An aldohexose is a monosaccharide with six carbon atoms and an aldehyde functional group. It is an example of a hexose, which is a six-carbon sugar.The open-chain form of an aldohexose contains multiple chiral centers, which are carbon atoms that are bonded to four different groups. These chiral centers can exist in two different configurations, resulting in a total of 2^n stereoisomers (where n is the number of chiral centers).Therefore, to determine the number of chiral carbons in an open-chain form of an aldohexose, we must count the number of carbon atoms that are bonded to four different groups.Each carbon atom in an aldohexose can be bonded to one of two types of groups: a hydroxyl group (-OH) or a hydrogen atom (-H). The first carbon atom in the chain (the aldehyde carbon) is not a chiral center since it is bonded to two identical groups (-H and -CHO).

Le Chatelier's Principle states that if a system at equilibrium is subjected to a stress, the equilibrium will shift in a direction that tends to counteract the stress and restore equilibrium

The chemical reactions involved in the addition of NH3(aq) or HCl(aq) to CuSO4 can be represented as follows:

CuSO4 + 4NH3(aq) → Cu(NH3)4SO4(aq)

When NH3(aq) is added to a CuSO4 solution, it reacts with the copper ions, forming the complex ion Cu(NH3)4^2+. This reaction consumes some of the Cu2+ ions in solution, causing the concentration of Cu2+ to decrease. To counteract this decrease, the equilibrium will shift to the right, resulting in more CuSO4 dissociating into Cu2+ ions and SO4^2- ions, according to Le Chatelier's Principle. This causes an increase in the concentration of Cu2+ ions, which is visible as a shift in colour from blue to deep blue.

Whereas, NH3(aq) acts as a ligand and forms a complex ion with the Cu2+ ion, leading to a decrease in the concentration of Cu2+ ions.

CuSO4 + 2HCl(aq) → CuCl2(aq) + H2SO4(aq)

When HCl(aq) is added to a CuSO4 solution, the H+ ions react with the SO4^2- ions to form H2SO4- ions, resulting in a decrease in SO4^2- concentration. To counteract this decrease, the equilibrium will shift to the left, resulting in more CuSO4 dissociating into Cu2+ ions and SO4^2- ions, according to Le Chatelier's Principle. This causes an increase in the concentration of Cu2+ ions, which is visible as a shift in colour from blue to deep blue.

Elements are pure substance

Answer:

a) Li and Cl, because one is a metal and the other is a nonmetal

Explanation:

An ionic compound is usually formed between a metal and a non metal. Recall that an ionic bonds involve the transfer of electrons from the metal to the non-metal.

in an ionic bond,  there must  be a significant difference between the electro negativities of the bonding atoms for electron transfer to occur. This is why the ionic bond only occurs between a metal and a non-metal.

The proportional sizes of the cations and anions determine the structure of an ionic molecule. Salts, oxides, hydroxides, sulfides, and the majority of inorganic compounds are examples of ionic compounds. Here among the given options, the correct option is a.

Ionic compounds are defined as substances that are joined by ionic bonds. In order to reach their closest arrangement as a noble gas, elements can either gain or lose electrons. For the completion of the octet, ions are formed (either by gaining or losing electrons), which aids in their stabilization.

In the compound LiCl, Li is a metal and Cl is a non-metal. Ions with the opposite charge are carefully packed together to form crystalline solids. Ionic compounds typically result from reactions between metals and non-metals.

Answer:

1.2 moles

Explanation:

this is the balanced equation for the reaction of oxygen (O2) and hydrogen (H2), usually we don't write the 1 in front of O2

2H₂ + 10₂ → 2H₂O

the molar ratio of hydrogen to oxygen is 2 : 1

we are trying to react with 2.4 mol of H2 so the moles of O2 is half the number of moles of H2 = 2.4 ÷ 2 = 1.2 mol

another way to think of it:

2H₂ + 10₂

2 : 1

2.4 mol : x mol

to get from 2 to 2.4 multiply by 1.2, so do the same to the other side

1 × 1.2 = 1.2 mol

Answer:

more energy is absorbed when the bonds in the reactants are broken

Therefore, the temperature change in the water due to the sheer drop of 543ft is approximately 76.7°F.

The steady flow energy equation is given by the expression;

(P/γ) + (v²/2g) + Z = constant

Where P/γ is the pressure energy, v²/2g is the kinetic energy, and Z is the potential energy.

Since the flow of the water is steady, we can assume that the total energy at the top of the falls is equal to the total energy at the bottom of the falls.

Consider the top of the waterfall, where the potential energy is 0, and the water is at the initial temperature T1.

At the bottom of the waterfall, the kinetic energy is negligible compared to the potential energy.

Therefore, the energy equation can be simplified as;

0 + (v²/2g) + Z₂ = (P/γ) + 0 + Z₁

Where Z₂ is the elevation of the bottom of the waterfall, and Z₁ is the elevation of the top of the waterfall.

Assuming that the water temperature at the bottom of the waterfall is T2, we can calculate the temperature change in the water as;

T₂ - T₁ = (v²/2Cp)

where Cp is the specific heat of water.

To estimate the velocity of the water at the bottom of the falls, we can use the Bernoulli's equation, which relates the pressure energy and kinetic energy of the water.

P₁/γ + v₁²/2g = P₂/γ + v₂²/2g

where P₁ is the pressure at the top of the waterfall, P₂ is the pressure at the bottom of the waterfall, v₁ is the velocity of the water at the top of the waterfall, and v₂ is the velocity of the water at the bottom of the waterfall.

Since the waterfall is open to the atmosphere, we can assume that the pressure at the top and bottom of the waterfall is atmospheric pressure

(P₁ = P₂ = Patm).

Therefore, the Bernoulli's equation can be simplified as;

v₂²/2g = v₁²/2g + Z₂ - Z₁

The height of the waterfall is 543ft, which is equal to 165.5m.

Using this value, we can estimate the velocity of the water at the bottom of the waterfall as;

v₂²/2g = v₁²/2g + 165.5m

Solving for v₂, we get;

v₂ = √(v₁² + 2g*165.5m)

Substituting this value in the expression for temperature change, we get;

T₂ - T₁ = (v₁² + 2g*165.5m)/2Cp

Now, let's estimate the velocity of the water at the top of the waterfall. According to the information given in the problem, the waterfall has a sheer drop, which means that the water falls freely without any obstruction.

Therefore, we can assume that the water at the top of the waterfall is at rest, and the velocity at the bottom of the waterfall is equal to the free-fall velocity of an object dropped from a height of 543ft, which can be estimated using the equation;

v = √(2gh)

where h is the height of the fall. Substituting the values, we get;

v = √(2*9.81m/s²*165.5m)

v = 57.4m/s

Therefore, the temperature change in the water can be estimated as;

T₂ - T₁ = (57.4m/s)²/2Cp + 2*9.81m/s²*165.5m)/2Cp

T₂ - T₁ = 42.6°C or 76.7°F

Phenol would not show up under UV as it does not possess any extended conjugated systems, which are responsible for absorbing UV light.

Phenol does not show significant absorption in the UV range because it lacks extended conjugated systems.

UV absorption typically occurs when a molecule contains conjugated double bonds or aromatic systems.

These conjugated systems allow for the delocalization of pi electrons, which creates a series of energy levels.

When UV light of appropriate energy interacts with these energy levels, electronic transitions can occur, resulting in absorption of the UV light.

In contrast, compounds like eugenol, anisole, and 4-tertbutylcyclohexanone contain extended conjugated systems due to the presence of multiple double bonds or aromatic rings.

These compounds are more likely to absorb UV light because of their conjugated structures.

Therefore, Phenol would not exhibit significant absorption in the UV range.

The mass of 0.105 mole of sucrose is 36 g.

Number of moles of sucrose (C12H22O11) = 0.105 moles

Mass of 1 mole of sucrose (C12H22O11) = 342.3 g

According to the Avogadro’s Law, “Equal volumes of all gases, at the same temperature and pressure, have the same number of molecules.”This law helps to establish the relationship between the number of moles and the mass of the substance.

The mass of one mole of any substance is called its molar mass.The molar mass of sucrose (C12H22O11) is calculated by summing up the masses of all the atoms present in its molecular formula.

n = Number of moles of sucrose (C12H22O11)

M = Mass of 1 mole of sucrose (C12H22O11)

The formula for the calculation of mass of sucrose is, m = n × M

Putting the values of n and M, we get, m = 0.105 mol × 342.3 g/mol

M = 36.0 g

Therefore, the mass in grams, of 0.105 mole of sucrose (C12H22O11) is 36.0 g.
