The amount of NaOH required is twice that of H₂SO₄. According to the balanced equation.
Define diprotic acid.Diprotic Acid(also called dibasic acid) an acid that can donate two hydrogen ions (H+) or protons per molecule in aqueous solution. A dibasic acid is a type of polybasic acid that can donate multiple protons per molecule. Examples: sulfuric acid (H₂SO₄) and carbonic acid (H₂CO₃). The number of equivalence points in the titration curve of polybasic acids depends on the number of acidic protons in the acid. Therefore, the titration curve has two equivalence points because we titrated diprotic acid with two acidic protons.
According to the balanced chemical formula:
2NaOH + H₂SO₄ → Na₂SO₄ + 2H₂O
The mole ratio of H₂SO₄ and NaOH is 1:2. This means that 2 moles of NaOH are required for each mole of H₂SO₄.

When exactly half of the ch3co2h has been converted to ch3co2-, what is the ratio:.
The ratio of converting CH3CO2 is 49:1.
Calculation:-
The pH of an acidic buffer is calculated by Henderson equation as:
pH = pKa + log [ salt] / [acid]
Given, ka for acetic acid = 1.76 x 10^-5
Therefore, pKa = -log ka = - log 1.76 x 10^-5
= 5 - log 1.76 = 5 - 0.246 = 4.75
pH = 4.44
Hence, using Henderson's equation,
pH = pka + log [CH3COO- ] /[CH3COOH]
4.44 = 4.75 + log [CH3COO- / CH3COOH]
log [CH3COO- / CH3COOH ] = - 0.31
[CH3COO- / CH3COOH] = antilog -0.31 = 0.49
Therefore, ratio of , [CH3COO- / CH3COOH] = 0.49 : 1
Ratios indicate how often one number contains another number.

The element you would get after fusion process of two carbon-12 atoms is Mg.
A magnesium-24 nucleus (Z = 12, A = 24) has the same nucleons as two carbon-12 nuclei (Z = 6, A = 12). The reaction is therefore a fusion of two carbon-12 nuclei, and no other particles are produced: [tex]^{12}_{6}C +^{12} _{6} C ------ > ^{24}_{12}Mg[/tex]
Nuclear fusion process: A reaction known as nuclear fusion occurs when two or more atomic nuclei fuse to create new atomic and subatomic particles (neutrons or protons). Energy is released or absorbed depending on how much mass there is between the reactants and products. The difference in nuclear binding energy between the atomic nuclei before and after the reaction is what causes this mass difference. Large amounts of energy are generated during nuclear fusion process, which fuels active stars, main sequence stars, and other high-magnitude stars.

What is freezing point?
The precise temperature at which a liquid solidifies is known as its Freezing Point. The freezing point, like the melting point, rises with increasing pressure.
The freezing point of mixtures and individual organic compounds is lower than the melting point. When these mixes begin to freeze, the solid that forms at first has a different composition than the liquid.
Freezing-point Depression is a decrease in the temperature at which a substance freezes caused by the addition of a smaller amount of another, non-volatile substance. Adding salt to water (used in ice cream makers and to de-ice roads), alcohol in water, ethylene or propylene glycol in water (used in car antifreeze), adding copper to molten silver (used to make solder that flows at a lower temperature than the silver pieces being joined), or mixing two solids such as impurities into a finely powdered drug are some examples.
This creation significantly alters the composition of the remaining liquids, usually in a way that gradually lowers the freezing point.

the sodium sulfate is added at the end of the procedure as a drying agent. which is/are the most important intermolecular forces between the sodium sulfate and the water?
Sodium sulfate is an ionic moiety that is completely dissociated into sodium cations and sulfate anions. Such dissociated ionic species, when interacting with water, a polar protic solvent, present two strong intermolecular forces.
Firstly in water, the hydrogens are attached to highly electronegative oxygen making the H atoms electron-deficient. To make up for this deficiency they seek electron-rich atoms like the oxygens of sulfate ion which share their lone pair of electrons with the electron-deficient H atoms and thus stabilize themselves as well as the H atoms. This IMF is called hydrogen bonding and apart from existing between sulfate ions and water, exists between water molecules themselves.
The second IMF is the ion-dipole interaction between the partially negative charge-bearing O atom of water and the cation sodium of sodium sulfate. This interaction is similar to the electrostatic attraction between sodium and sulfate but does not involve complete electron transfer. The ion-dipole interaction can be seen as a type of H-bonding, only involving cations instead of electron-deficient hydrogen atoms. By their number, these two IMF between sodium sulfate and water allows the former to sequester water molecules in diethyl ether.

The partial pressure of each gases is dependent on the mole fraction of the gases. If gas b has higher partial pressure than the a , then the number of moles of b will be higher in the container.
What is partial pressure?Partial pressure of an individual gas in a mixture of gases is the contribution of that gas to the total pressure of the gas mixture. Thus if Pa be the partial pressure of gas A and Pb is the partial pressure of gas b, then the total pressure of mixture AB will be Pa + Pb.
Given that the two gases a and b are taken in a container 5 g each. The partial pressure of b is twice that of a. Thus,
Pb = 2 Pa. and total pressure = Pa + 2Pa = 3Pa

A solution's mass fraction (or weight fraction) is the proportion of one component's mass to the overall mass of the solution.
Weight percent = mass solute/mass solute + mass solvent ×100
Weight percent = 2.6/2.6+55 ×100
Weight percent = 4.51% of vitamin c.
