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

moles of SO₂ =  1.56 moles

Convection is a type of heat transfer in which a fluid experiences an energy transition. Radiation refers to the process by which heat is transferred between objects without direct physical contact.

Through the process of conduction, heat is transferred directly from one object to another. Convection is a type of heat transfer in which a fluid experiences an energy transition. Radiation refers to the process by which heat is transferred between objects without direct physical contact.

Direct contact between the objects is how heat is transferred during conduction. The heat is transferred within the fluid during convection. Heat transfer in radiation happens through electromagnetic waves without the use of particles. The temperature difference causes heat transfer to occur.

Bumping is the sudden and uncontrolled boiling of liquid.

Bumping is a word used in chemistry to describe the situation where homogeneous liquids boiled in a test tube or other container will superheat and, upon nucleation, rapid boiling will expel the liquid from the container. This happens when liquids are heated up beyond their boiling points and it causes them to burst out of their containers.

Explanation:

Questions based on observations or on data from experiments are the ones that science can most likely help with.

Answer:

2031 g or 2.03 kg

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. A precipitate is a stable substance that separates from the solution as in a chemical reaction.

To increase the water solubility of resorcinol or salicylic acid, 3m naoh is used to dissolve them. the reason why they dissolve better in NAOH than in water is because resorcinol as well as salicylic acid have some measures of acidic hydrogens and so they can be ionized inside of NaOH.

Salicylic acid must be transformed into salicylate because it is insufficiently soluble in water at room temperature to produce the composition you want.

Note that Salicylic acid can be used to accomplish this by reacting with sodium bicarbonate (baking soda) in water; the salicylic acid will dissolve during the reaction.

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:

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:

lysozyme, an enzyme found in human saliva, tears, and other secretions, catalyzes the hydrolysis of the beta-1,4-glycosidic linkages and peptidoglycan. This enzyme degrades the bacterial cell wall but it is suitable for human health by preventing bacterial infection.

What is hydrolysis?

The cleavage of biomolecules known as biological hydrolysis occurs when a water molecule is consumed in order to cause the division of a bigger molecule into its component parts. Saccharification is the process of hydrolyzing a carbohydrate into its individual sugar molecules, as occurs when sucrose is broken down into glucose and fructose.

The beta one for, say, acidic connections, an urgent analogy that will demolish the bacterial cell wall. By destroying their peptidoglycan, it breaks down the bacterial cell wall. In addition, since we lack peptidoglycan in our bodies, an enzyme that kills bacteria won't have the same impact on human cells. This is excellent for human health since it can help stop bacterial infections. Because it will presumably destroy microorganisms, we detect it in human secretions that come into contact with the environment, such as tears and saliva.

Answer:

both the original and the new genes

Explanation:

if, at a given temperature, the equilibrium constant for the reaction

H₂  +  Cl₂    ---->  2HCl   is Kp, then the equilibrium constant for the reaction : 2HCl ---->  H₂  +  Cl₂ is 1 / Kp.

the equilibrium constant for the reaction

H₂  +  Cl₂    ---->  2HCl        is Kp,

when we reverse the equation  the equilibrium constant becomes reciprocal of original reaction . so the reaction is given as:

2HCl ---->  H₂  +  Cl₂

this is the reverse reaction of the original reaction ,so the equilibrium constant becomes the reciprocal of the original reaction.

so, the equilibrium constant K'p = 1/ Kp

Thus, if, at a given temperature, the equilibrium constant for the reaction

H₂  +  Cl₂    ---->  2HCl   is Kp, then the equilibrium constant for the reaction : 2HCl ---->  H₂  +  Cl₂ is 1 / Kp.

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.

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:
