When the equation NaOH H2SO4 → is completed and balanced one of the products is ___?

Volume = amount in mol × 22.4 is used to calculate gas volume at STP.

Ideal gas law states PV = nRT So, the volume of an ideal gas is 22.4 L/mol at STP.

STP is 273 Kelvin and 1 atmosphere (atm), the standard unit for atmospheric pressure.

At STP, 1 mole of gas takes up 22.4 liters. Let’s put those numbers into the ideal gas law.

The molar mass of a gas can be derived from the ideal gas law, PV=nRT , by using the definition of molar mass to replace n , the number of moles.

Total energy required to warm 1 kg of ice is 834.3 KJ. This is calculated using latent heat and specific heat.

We can calculate the amount of heat required to raise the temperature of 1 kg of ice from -40°C to 0 °C from the latent heat of fusion. Latent heat is the energy absorbed or released by a substance during a change in its physical state that occurs without changing its temperature.

Quantity of heat =Mass x latent heat + mass x specific heat x (final - initial temp)

Mass is 1 kg.

Final temp = 0℃

Initial temp = -40℃

Latent heat of fusion for ice = 333.55 kJ/kg

Specific heat of ice 2.090KJ/kg °C

Specific heat is the the quantity of heat required to raise the temperature of one gram of a substance by one Celsius degree. The units of specific heat are usually calories or joules per gram per Celsius degree.

Total heat required = 2*333.55 + 2* 2.090 *(0- (-40))

The reaction of elements x from group 2 with elements from group 7 of the periodic table will produce a compound where both cations and anions are present.

This group makes up the so-called alkaline earth metals and is made up of: beryllium, magnesium, calcium, strontium, barium and radium.

These elements make up what is called the manganese family and have the particularity of being metals with 7 valence electrons.

The valence electrons of manganese and its family of elements are distributed 2 in the last shell and 5 in the penultimate shell.

An example of a compound formed by manganese and alkaline earth is calcium permanganate. It is an oxidizing agent that is formed by a metallic cation of calcium and two anions of permanganate.

According to Boyle's law, in any ideal gas, the pressure exerted by the gas and its volume is inversely proportional to one another, considering it to be at a constant temperature.

This law is applicable in case of respiration also. When the air is inhaled, the diaphragm is raised, as a result of which the pressure exerted on the lungs increases and eventually allows the air to flow into the lungs.

We use Boyle Mariotte's formula: for a given mass of gas at constant temperature, the pressure and volume vary inversely proportionally.

We convert the unit volume in ml into

L: 200 / 1000 = 0.2  and 50 / 1000=0.05

P₁xV₁=P₂xV₂

V₂= (P₁xV₁)/P₂

15.63 moles of HgO are needed to produce 250.0 grams of oxygen.

From the decomposition of HgO, we get mercury and oxygen:

Now, we need to find moles of HgO needed to produce 250.0 grams of oxygen.

So, the Mass of O₂ = 250.0 grams

Number of moles of the oxygen = Mass of Oxygen/Molar mass

The standard enthalpy change for the reaction 2H2O (l) → 2H2 (g) + O2 (g) is -873.6 kJ/mol.

The standard enthalpy change (ΔH°) for a reaction is the enthalpy change when all reactants and products are in their standard states (at 1 atm pressure and a specified temperature, usually 25°C).

The standard enthalpy change for the reaction 2H2O (l) → 2H2 (g) + O2 (g) can be calculated using the standard heats of formation of the reactants and products as follows:

ΔH°rxn = [ΔH°f (H2O, l) x 2] + [ΔH°f (H2, g) x 2] + ΔH°f (O2, g)

ΔH°rxn = [-285.8 kJ/mol x 2] + [-241.8 kJ/mol x 2] + 0 kJ/mol

ΔH°rxn = -873.6 kJ/mol

If the spot was placed below the solvent level, this would cause the sample to be dissolved into the solvent pool before traveling up the plate.

TLC should be positioned so that just the lowest edge of the plate touches the solvent.

Differential affinities (strength of adhesion) of the analyte components towards the stationary and mobile phases result in differential separation of the components. Affinity, in turn, is determined by two molecular properties: adsorption and solubility.

Adsorption is the property of how well a component of a mixture clings to the stationary phase, whereas solubility is the quality of how well a component of a mixture dissolves in the mobile phase.

The greater the adsorption to the stationary phase, the slower the molecule will move across the column.

The more the molecule adsorbs to the stationary phase, the slower it moves across the column.

The greater the molecule's solubility in the mobile phase, the faster it will travel across the column.

7,493.1 g of methanol must be dissolved in 313.0 mL of ethanol to prepare a 0.750 M solution.

What is dissolved?

Dissolved is a term used to describe when a solid material has been completely broken down into particles small enough to be suspended in a liquid. This process is known as dissolution, and can be achieved through a variety of different methods. One of the most commonly used methods is mechanical agitation, which involves using mechanical force such as stirring or shaking to cause the solid particles to break down and become suspended in the liquid. This process can be used to dissolve a wide range of different compounds such as salts, sugars, and acids. Other methods of dissolution include chemical reactions, heating, and the use of solvents. Dissolution is a key part of many chemical processes, and its importance in chemistry cannot be overstated.

Molar mass of methanol (CH3OH): 32.04 g/mol
Molarity of solution: 0.750 mol/L
Volume of solution: 313.0 mL
Therefore, the number of moles of methanol required in solution = 0.750 mol/L × 313.0 mL = 234.75 moles
Mass of methanol required = 234.75 moles × 32.04 g/mol = 7,493.1 g

The empirical formula of the compound is Na2S3O. To determine the empirical formula of a compound, you need to know the mass of each element present in the compound and the percentage of each element by mass.

An empirical formula is a chemical formula that represents the simplest ratio of atoms in a compound. It shows the types and numbers of atoms present in a molecule, but not the actual arrangement or bonding of the atoms.

To find the empirical formula of a compound, we need to determine the simplest whole number ratio of the elements in the compound. To do this, we first need to convert the percentages of each element to masses.

36.48% Na corresponds to 36.48 g of Na in 100 g of the compound.

25.41% S corresponds to 25.41 g of S in 100 g of the compound.

38.11% O corresponds to 38.11 g of O in 100 g of the compound.

Next, we need to convert the masses of each element to moles. To do this, we use the atomic masses of the elements. The atomic mass of Na is 22.99 g/mol, the atomic mass of S is 32.06 g/mol, and the atomic mass of O is 15.99 g/mol.

36.48 g of Na corresponds to 1.585 moles of Na.

25.41 g of S corresponds to 0.792 moles of S.

38.11 g of O corresponds to 2.385 moles of O.

Finally, we need to find the ratio of moles of each element. To do this, we divide each value by the smallest value. In this case, the smallest value is 0.792 moles of S.

1.585 moles of Na / 0.792 moles of S = 1.995

0.792 moles of S / 0.792 moles of S = 1

2.385 moles of O / 0.792 moles of S = 3.005
