The number of moles SO₂ that are present in 100g of SO₂ 1.56 moles.

The moles of a substance is related to the mass of the substance  and the molar mass as follows:

the molar mass of a substance is the mass of 1 mole of the substance.

Molar mass of SO₂ = 32 + 16 * 2

Molar mass of SO₂ = 64

mass of SO₂ in the sample = 100 g

moles of SO₂ = 100 / 64

The frequency of a wave is V = 4.4 x [tex]10^{2}[/tex] [tex]s^{-1}[/tex].

The visible light spectrum is the part of the electromagnetic spectrum that can be seen by the human eye. This wavelength range is simply called visible light. Normally the human eye can see wavelengths between 380 and 700 nanometers. Visible light made up of the individual colors of the rainbow is only a small part of the electromagnetic spectrum. Another kind of light is radio waves.

The wavelength of light waves is approximately 400 to 700 nanometers 4,000 to 7,000 angstroms. Our eyes perceive different wavelengths of light as rainbow colors. Red light has a relatively long wavelength approximately 700 nm in length. Blue and violet light have short wavelengths of about 400 nm and the visible light spectrum is part of the spectrum of electromagnetic radiation visible to the human eye.

Explanation:

The percent by mass of sodium bicarbonate in the sample mixture is 67%.

Sodium bicarbonate reacts with a monoprotic acid HA in the following manner:
[tex]NaHCO_{3} + HCl[/tex] → [tex]NaCl + H_{2}O+CO_{2}[/tex]

This means that 1 mole of sodium bicarbonate produces 1 mole of carbon dioxide. We can use this to set up a proportion:

84.01 g of sodium bicarbonate : 44.01 g of carbon dioxide = X : 0.561 g of carbon dioxde

X is equal to the mass of sodium bicarbonate in the sample.

X = 84.01 g * 0.561 g / 44.01 g = 1.08 g of sodium bicarbonate

The percent by mass is calculated using the following equation:

%w = 100% * mass of sodium bicarbonate / mass of mixture = 100% * 1.08 g / 1.62 g = 67%

Considering the Combined Law Equation, the pressure of Cl₂ if the volume is increased to 0.800 l and the temperature increased to 55 °C is 114.367 mmHg.

Boyle's law states that the pressure of a gas in a closed container is inversely proportional to the volume of the container, when the temperature is constant: if the pressure increases, the volume decreases while if the pressure decreases, the volume increases.

Mathematically, this law is expressed as:

P×V= constant

Gay-Lussac's law states that the pressure of a gas is directly proportional to its temperature when the volume is constant: increasing temperature increases pressure, while decreasing temperature decreases pressure.

Mathematically, this law is expressed as:

P÷T= constant

Charles's law states that the volume is directly proportional to the temperature of the gas when the pressure is constant: if the temperature increases, the volume of the gas increases while if the temperature of the gas decreases, the volume decreases.

Mathematically, this law is expressed as:

V÷T= constant

Combined law equation is the combination of three gas laws called Boyle's, Charlie's and Gay-Lusac's law:

(P×V)÷T= constant

Considering an initial state 1 and a final state 2:

(P₁×V₁)÷ T₁= (P₂×V₂)÷ T₂

In this case, you know:

Replacing in Combined law equation:

(475 mmHg× 0.175 L)÷ 298 K= (P₂× 0.800 L)÷ 328 K

Solving:

[(475 mmHg× 0.175 L)÷ 298 K] × (328 K÷ 0.800 L)= P₂

114.367 mmHg= P₂

Finally, the new pressure will be 114.367 mmHg.

According to the given statement if the mass of the stone was 25g was its density 5 g/cm³.

Density is the ratio of a material's mass to its volume. The formula for density is d = M/V, where d denotes density, M is mass, and V is volume. Density is typically measured in grams per cubic centimeter.

Despite the fact that the SI unit of density is kg/m3, we instead use g/cm3 for solids, g/ml for liquids, and g/L for gases out of convenience.

Mass = 25 g

Volume = 7 mL – 2 mL

Volume = 5 mL

Volume = 5 cm³

Density = mass/volume

Density = 25 g/5 cm³

Which of the following factors can precipitate as po₄³⁻ ions in an aqueous solution: ca²⁺.

Precipitate: In chemistry, a stable substance occurs due to a chemical reaction that reduces the solubility of a solid or an exchange of reactions due to a change in temperature. In meteorology, precipitation is liquid or strong water falling from the sky (rain, snow, etc.). Fehling's solution is blue due to dissolved Cu2. When silver nitrate and sodium chloride are mixed with water, the silver chloride precipitates out of the solution as a heavy precipitate. In this situation, the precipitate is silver chloride.

A precipitate has a strong form in a chemical reaction that is unique to both reactants. This occurs when solutions containing ionic compounds combine to form insoluble products. Sediment identification can usually be addressed by reviewing solubility recommendations. The correct answer is a homogeneous aggregate of two or more materials.

Both atmosphere density and atmospheric pressure decrease with the increase in altitude.

Atmosphere density decreases as we go up in altitude because the composition of the atmosphere changes in favor of lighter gases, lowering the overall density of the mixture.

On the other hand, with the increase in altitude, the height of the column of air above us decreases, and that air also becomes less dense, resulting in lower atmospheric pressure at higher altitudes. One interesting consequence of this is that, for example, the boiling point of water decreases, so that at the top of Mount Everest, water boils at 68 °C.
