Which best describes the law of conservation of mass? The coefficients in front of the chemicals in the reactants should be base

d on the physical state of the products. Products in the form of gases are not considered a part of the total mass change from reactants to products. When reactants contain both a solid and a liquid, the solid counts toward the overall mass and the liquid does not. The mass of the reactants and products is equal and is not dependent on the physical state of the substances.

solong [7]

Answer:

One mole of a substance is equal to 6.022 × 10²³ units of that substance (atoms, molecules, or ions)

Explanation:

This number is Avogadro's number. The concept of the mole can be used to convert between mass and number of particles. its used to compare very large numbers.

Iron iii chloride ammonium hydroxide balanced equation, complete ionic equation, net ionic equation
Vladimir [108]
Iron III Chloride has a chemical formula of FeCl₃, while ammonium hydroxide has a chemical formula of NH₄OH. 

The <em>balanced equation</em> would be:

FeCl₃ (aq) + 3 NH₄OH (aq) → Fe(OH)₃ (s) + 3 NH₄Cl (aq)
The precipitate is Fe(OH)₃ or iron iii hydroxide.

To find the <em>complete ionic equation</em>, dissociate the compounds in aqueous phases into their ionic forms:

Fe³⁺ + Cl⁻ + NH₄⁺ + 3 OH⁻ -->  Fe(OH)₃(s) + NH₄⁺ + Cl⁻ 

To find the <em>net ionic equation</em>, cancel out like ions that appear both in the reactant and product side:

Fe³⁺ +  3 OH⁻ -->  Fe(OH)₃

Charra [1.4K]

Hypoventilation can cause oxygen levels to fall too low, a condition called Hypoxia and carbon dioxide levels may rise too high, a condition called Hypercapnia.

Hypoxia is a state in which there is insufficient oxygen reaching the tissues of the body or a specific area of the body.

Generalized hypoxia, which affects the entire body, and local hypoxia, which affects a specific area of the body, are the two types of hypoxia.

Although fluctuations in arterial oxygen concentrations are frequently associated with clinical conditions, they can also occur naturally during severe physical activity or hypoventilation training.

A rise in carbon dioxide partial pressure (PaCO2) above 45 mmHg is referred to as hypercapnia.

The body produces carbon dioxide as a metabolic byproduct of its numerous cellular functions, and it has a number of physiological systems at its disposal to control its levels.
