Actually each molecule of Hb can bind four oxygen molecules. So given 1 x 10^6 Hb, so there are 4 x 10^6 binding sites available.
If only 50% of the Hb are bound, so this means that 2 x 10^6 binding sites are occupied by O2. However we must remember that hemoglobin binding is an all-or-nothing phenomenon. Meaning that each molecule of Hb binds four molecules of oxygen or zero at all.
If 23% is saturated, so the number of binding sites occupied is 0.92 x 10^6 binding sites or 9.2 x 10^5 binding sites.

Aqueous lithium sulfate was mixed with aqueous strontium chlorate, and a crystallized strontium sulfate product was formed. consider the other product and its phase, and then write the balanced molecular equation for this precipitation reaction
Lithium sulfate is Li2SO4
Strontium chlorate is Sr(ClO3)2
Strontium sulfate is SrSO4
So the complete balanced chemical reaction for this is:
Li2SO4 (aq) + Sr(ClO3)2 (aq) --> SrSO4 (s) + 2 LiClO3 (aq)
This is a type of double replacement reaction since there is an exchange of ions.
In a precipitation reaction between aqueous lithium sulfate and strontium chlorate, strontium sulfate precipitates while lithium chlorate remains aqueous. The balanced molecular equation for this reaction is: Li2SO4 (aq) + Sr(ClO3)2 (aq) → SrSO4 (s) + 2 LiClO3 (aq).
Explanation:When aqueous lithium sulfate (Li2SO4) is mixed with aqueous strontium chlorate (Sr(ClO3)2), one product that forms is strontium sulfate (SrSO4), which crystalizes due to its insolubility in water. The other product is lithium chlorate (LiClO3), which remains aqueous due to its high solubility.
The balanced molecular equation representing this precipitation is: Li2SO4 (aq) + Sr(ClO3)2 (aq) → SrSO4 (s) + 2 LiClO3 (aq).
This equation reflects the conversion of the reactants, lithium sulfate and strontium chlorate, into the products, strontium sulfate (a precipitate) and lithium chlorate.

Which ion will form a basic solution when dissolved in water? hso4-?
Final answer:
The hydrogen sulfate ion (HSO4-) will form a slightly basic solution when dissolved in water because it reacts to produce hydroxide ions (OH-) which increases the pH above 7.
Explanation:
The hydrogen sulfate ion (HSO4-) is the conjugate base of sulfuric acid (H2SO4) and the conjugate acid of sulfate (SO42-). When HSO4- is dissolved in water, it can react with water to form hydrogen sulfate (H2SO4) and hydroxide ions (OH-), which causes the solution to be basic. This is due to the fact that it slightly ionizes to produce OH- ions. Based on the reactions and comparative strengths of acids and bases, HSO4- being a conjugate base of a strong acid is a very weak base and will therefore form a solution that is slightly basic, provided that the resulting concentration of OH- ions is greater than that of H3O+ ions in the water.

If zinc chloride weighs 136.28 g/mol, what is its molecular formula? show calculations
The molecular formula of zinc chloride, which has a molar mass of 136.28 g/mol, is ZnCl2. This was determined by summing the molar mass of one zinc atom and two chlorine atoms.
Explanation:To find the molecular formula of zinc chloride, we need to know the atomic masses of zinc and chlorine. The atomic mass of zinc is approximately 65.38 g/mol whereas chlorine has an atomic mass of approximately 35.45 g/mol. Since we know that zinc chloride is composed of one zinc atom and two chlorine atoms (ZnCl2), we can calculate the molar mass as follows:
So, the molecular formula for zinc chloride is ZnCl2.

The molecular formula of zinc chloride, given a molar mass of 136.28 g/mol, is determined to be ZnCl2 by dividing the difference between the molar mass and the atomic mass of zinc by the atomic mass of chlorine and finding that there are approximately two chlorine atoms per zinc atom.
Explanation:The molecular formula of zinc chloride can be determined using its molar mass of 136.28 g/mol and the atomic masses of zinc (65.38 g/mol) and chlorine (35.45 g/mol). If we assume the formula is ZnClx, where x is the number of chlorine atoms, we can calculate x as follows:
Molar mass of ZnClx = atomic mass of Zn + (x)(atomic mass of Cl)
136.28 g/mol = 65.38 g/mol + (x)(35.45 g/mol)
Solving for x gives us:
x = (136.28 g/mol – 65.38 g/mol) / 35.45 g/mol
x ≈ 2
Therefore, the molecular formula of zinc chloride is ZnCl2.

What is atomic structure ?Atomic structure refers to the structure of atom which consists of a nucleus in the center with protons and neutrons being present inside the nucleus .Protons are positively charged sub atomic particles while the neutrons are sub atomic particles which are electrically neutral.
Outside the nucleus , in circular orbits there are electrons revolving around the nucleus with negative charge on each electron .The history of atomic structure dates back to the time of Democritus who proposed that matter is made up of atoms.
The study of atom gives a great insight about the wide range of chemical reactions , chemical bonds and their physical properties.To explain the atomic structure , various atomic models were proposed like Dalton's atomic theory ,Thomson's atomic model and Rutherford's atomic model and Bohr's atomic model.

Explain the conductivity results observed for sodium chloride in the solid state and in aqueous solution
NaCl when in solid state does not conduct electricity while it does in aqueous solution.
Explanation:
NaCl (or what we call common salt) first needs to be either melted or dissolved in a solution for it to conduct electricity. The reason for this is that electrons in a solid state does not have enough freedom to move to either the Cathode (-ve) or to the Anode (+ve). So in a liquid state the electrons are now free enough to move.
The ionic nature of sodium chloride (NaCl) influences its ability to conduct electricity. It is non-conductive in solid form as the ions are fixed and aren't able to move. However, in an aqueous solution or when molten, the ions dissociate and can freely move, enabling the conduction of electricity.
Explanation:Sodium chloride, or NaCl, displays different conductivity results in its solid state versus aqueous solution due to its ionic nature. When NaCl is in its solid state, it does not conduct electricity because the ions are fixed in place and cannot flow. It is said that electricity is the flow of charged particles, and in the case of a solid such as solid NaCl, these charged particles, i.e. ions, are unable to flow due to the rigid ionic lattice structure.
However, the situation changes when sodium chloride is in an aqueous solution or when it is molten. Sodium chloride, when dissolved in water, dissociates into ions, producing free flowing Na+ and Cl- ions. These ions are electrolytes and are capable of conducting an electrical current in solution. Similar thing happens when it becomes molten due to high heat, sodium chloride melts at around 801 °C, freeing the ions and allowing them to conduct electricity.

Answer:
When an atom absorbs energy, the electrons move from their ground state to an Excited state. when an atom emits energy, the electrons move from an excited state to their ground state and give off energy(radiation).
Explanation:
In An atom electrons sphere the positively charged nucleus in different energy orbits.
The low energy orbits present near the nucleus and high energy orbits are farther from the nucleus. when an electron absorbs energy it becomes excited and jumps to a high energy state and when it loses energy as the radiation it gets back to its ground state or low energy state.
