what is the ph of a .100M naclo solution

101 mmHg is the total pressure in the tank.

Thus, Dalton's Law of Partial Pressures states that while the volume and temperature of a gaseous mixture are held constant, the total pressure of the mixture is equal to the sum of the partial pressures of its gaseous components.

Nitrogen, oxygen, argon, carbon dioxide, water vapor, and a trace amount of other gases are all present in atmospheric air and pressure.

The increased oxygen content in the chamber can displace the CO bound to hemoglobin faster than air oxygen, hence the hyperbaric chambers are also used to treat carbon monoxide (CO) poisoning. The treatment of scuba divers with the bends is another application for hyperbaric chambers.

Thus, 101 mmHg is the total pressure in the tank.

Sedimentation, filtration, and coagulation are the treatments that will help remove contaminants from minerals or from the pipes carrying water from a source.

Sedimentation is a process in which suspended particles settle out of water. It is one of the most basic techniques for removing particles from water. As particles settle, they become trapped in the bottom of a container or settle to the ground in an outdoor setting

Filtration is a method of removing particles from a fluid. It is a physical or chemical separation method that separates solids from fluids (liquids or gases) by adding a medium through which only the fluid can pass.

Coagulation is the process of using chemicals to remove contaminants from water. By creating a chemical reaction, coagulation destabilizes particles and causes them to clump together. This helps to remove the contaminants from the water.

Disinfection is the process of eliminating or destroying pathogens that cause infection. Disinfection eliminates harmful microorganisms by destroying or inactivating them. The disinfectant is a chemical or physical agent that is used to destroy or inactivate harmful microorganisms.

Answer:

A. True

B. False

C. False

D. True

E. False

Explanation:

A. The proximal histidine covalently binds iron.

This statement is true because the proximal histidine is covalently bonded to the fifth coordination position of iron in myoglobin

B. The distal histidine covalently binds oxygen.

This statement is false because the distal histidine interacts with the oxygen covalently bonded to the sixty coordination position of iron by means of a hydrogen bond not a covalent bond.

C. The distal histidine binds iron

This statement is false because the distal histidine is not bonded to iron but to oxygen but stabilizes the oxygen bonded to iron

D. Free heme binds CO with the Fe, C and O atoms in a linear array.

This statement is true because free heme has more affinity for CO than O2 as it has the least steric hindrance when the Fe, C, and O atoms lie in a straight line. On the other hand, when O2 binds to free heme, the axis of the oxygen molecule is positioned at an angle to the Fe-O bond thereby producing significant steric hindrance.

E. The iron in heme binds the oxygen atom of CO.

This statement is false because the iron in heme binds to the carbon atom, C, of CO rather than to oxygen atom.

If an element has three valence electrons, it is most likely a metal.

In the periodic table, metals are found towards the left hand side of the table. Metals have fewer valence electrons than nonmetals. In the periodic table, there are more metallic than nonmetallic elements.

Answer:

a) [Cu(H2O)6]^2+

b) [CuCl4]^2-

Explanation:

a) The energy(E) of a photon is related to its wavelength(λ) via the planck's equation:

Therefore, energy and wavelength are inversely related.

The electromagnetic spectrum in the visible region extends from the high energy (low wavelength) blue end to the low energy (high wavelength) red region. For a given substance, absorption and emission are complementary to each other i.e. if the absorption occurs in the high energy region then photons will be emitted that corresponds to lower energy and vice versa. The wavelength region can be estimated based on the color wheel.

CuCl4^2- appears green, which implies that the absorption will occur in the red region

Cu(H2O)6^2+ appears blue which implies that the absorption will occur in the orange region

Red photons have a lower energy than the orange photons. Hence, Cu(H2O)6^2+ will absorb higher energy photons.

b) Copper (Cu) present in the given complexes is a transition metal with degenerate d -orbitals. Crystal field splitting removes the degeneracy of these 'metal' d-orbitals based on the strength of the ligands surrounding it.

As per the spectrochemical series, Cl is a strong field ligand compared to H2O. Hence, CuCl4^2- will have a larger splitting.

the cell potential for the given galvanic cell is +3.16 V at 25°C. This means that the reaction is strongly favored to occur spontaneously in the direction written, from left to right.

To calculate the cell potential for the given galvanic cell, we need to use the standard reduction potentials of the two half-reactions involved in the cell reaction. From the table of standard reduction potentials, we can find the following half-reactions:

Al³+ (aq) + 3e⁻ → Al(s) E°red = -1.66 V

Au³+ (aq) + 3e⁻ → Au(s) E°red = +1.50 V

To obtain the overall cell potential, we can use the equation:

E°cell = E°reduction (cathode) - E°reduction (anode)

where the cathode is the half-cell where reduction occurs and the anode is the half-cell where oxidation occurs. In this case, we can see that Au³+ is reduced to Au(s) (cathode) and Al(s) is oxidized to Al³+ (anode).

Therefore, we can calculate the cell potential as follows:

E°cell = E°red (Au³+ → Au) - E°red (Al → Al³+)

= (+1.50 V) - (-1.66 V)

= +3.16 V

Thus, the cell potential for the given galvanic cell is +3.16 V at 25°C. This means that the reaction is strongly favored to occur spontaneously in the direction written, from left to right.

Explanation:

The unit that is equivalent to 75g is 0.075 kg, 750 dg, and 7.5 dag. The correct options are b, c, and d.

Measuring units are the units used to denote the measurement quantities. There are seven basic measuring units. They are length, Time, Amount of substance, Electric current, Temperature, Luminous intensity, and Mass.

The current unit is given grams, which are used to measure the mass of any object.

1000 grams is equal to 1 kilogram and 1 dg = 0.1 g, and 1 dag = 10 g. So by this formula, each of the quantities can be calculated.  

1 kg = 1000 g

So, 0.075 kg = (0.075 × 1000)g = 75 g

1 dg = 0.1 g

So, 750 dg = (750 × 0.1) g = 75 g

1 dag = 10 g

So, 7.5 dag = (7.5 × 10) g = 75 g

Thus, the correct options are b. 750 dg, c. 7.5 dag, and d. .075 Kg.

The charge on aluminum when it forms an ion would be +3

The charge that the atom of an element carries depends on the number of valance electrons in its outermost shell and whether it is more likely to gain or lose electrons to achieve a stable state.

Aluminum atom has 3 valence electrons in its outermost shell. It either gains 5 more or donates the 3 valence electrons in order to achieve an octet state. Since it is easier to donate 3 than gain 5, the atom of aluminum will prefer to donate the 3 valence electrons to become stable.

Thus, the aluminum atom will form an ion by carrying +3 charge.
