There are two types of chemical compound one is covalent compound and other is ionic compound, covalent compound formed by sharing of electron and ionic compound formed by complete transfer of electron. Therefore, the IUPAC name of the Mg[tex]_3[/tex]P[tex]_2[/tex] is Tri magnesium Di phosphide.

Chemical Compound is a combination of molecule, Molecule forms by combination of element and element forms by combination of atoms in fixed proportion.

An ionic compound is a metal and nonmetal combined compound.  Ionic compound are very hard. They have high melting and boiling point because of strong ion bond. The IUPAC name of the Mg[tex]_3[/tex]P[tex]_2[/tex] is Tri magnesium Di phosphide. The oxidation state of phosphide is -3.

Therefore, the IUPAC name of the Mg[tex]_3[/tex]P[tex]_2[/tex] is Tri magnesium Di phosphide.

Answer:

In chemistry, the law of conservation of mass states that the mass of the products (the chemical substances created by a chemical reaction) will always equal the mass of the reactants (the substances that make the chemical reaction). Think of it as being similar to balancing an algebraic equation.

Explanation:

(winks and runs off)

Answer:

Mass cannot be created or destroyed.

Explanation:

        Conservation of mass is "a principle stating that mass cannot be created or destroyed" (Oxford Languages).

If excess solvent is added, discard the entire solution and begin the process of preparing the solution afresh.

It is common to prepare solutions using a standard volumetric flask. In this method, the required amount of solid or liquid is added to the volumetric flask and made up to mark with solvent.

Sometimes, it is possible to mistakenly exceed the mark as the solvent is added. In such cases, you must discard the entire solution and begin the process of preparing the solution afresh.

Explanation:

A catalyst is a substance that increases the rate of a chemical reaction by lowering the activation energy without itself being consumed by the reaction.

Activation energy is the minimum amount of energy required for a chemical reaction to proceed in the forward direction.

Apply the fertilizer.

Answer:

Organic fertilizers are an essential source for plant nutrients and a soil conditioner in agriculture. Due to its sources and the composition of the organic inputs as well as the type, functionality and failures of the applied treatment process, the organic fertilizer may contain various amounts of infectious agents and toxic chemicals, especially the antibiotics that can be introduced to the subsequent food chain. A range of human and animal pathogens of bacterial, viral and parasitic origin have been the cause of food-borne epidemics due to unintended contamination from organic fertilizers. The use of antibiotics by humans and in animal feeds will also end up in the organic fertilizers. These antibiotics and other chemicals, depending on the sources of the organics, will enhance the likelihood of occurrence of resistant and multi-resistant strains of microorganisms in society and have been reported to cause ecotoxicological environmental effects and disruption of the ecological balance. Exposure of microorganisms to sublethal concentration of antibiotics in the organic products induces antibiotic resistance. WHO guidelines for the reuse of excreta and other organic matters identify the risk for the exposed groups to the reuse of the

Answer:

Theoretical value is the value a scientist expects from an equation, assuming perfect or near-perfect conditions. Experimental value, on the other hand, is what is actually measured from an experiment. Rarely (in fact never) are these numbers the same.

Take the area of a sheet of paper. I know that the area of a rectangle can be found by multiplying the lengths of both sides together. I can assume an 8.5x11 sheet, so I calculate exactly 93.5 square inches. This is my theoretical value. When I actually do the measurements on my paper, it turns out my paper has been slightly cut on one end, or I’m measuring with a shoddy ruler. Therefore, I might measure only 92.8 square inches. This is my experimental value. See thats it’s close, but not exact.

Expanding on this concept, quantum mechanics is so widely accepted in the scientific community because many theoretical values calculated by mathmaticians concurred with experimental values to many, many decimal places. These would be constants such as Plank’s Constant, energy levels of harmonic potentials, and energy levels of the hydrogen atom.

Explanation:

Theoretical result is based on information and mathematics. Trials or experiments are the foundation of experimental result. What ought to occur is theoretical probability. What actually occurs is experimental probability.

The definition of theoretical probability. It is not necessary to do the experiment and then analyze the findings for theoretical probability. The theoretical probability, however, represents what you anticipate will occur in an experimnet.

In experimental probability, information is gathered via repeated experimentation. In theoretical probability, data is gathered without doing the experiment by taking into account every possibility that has a chance of occurring.

The theoretical yield of carbon dioxide, CO₂ obtained from the reaction is 8.93 g

We'll begin by calculating the mass of citric acid, H₃C₆H₅O₇ that reacted and the mass of carbon dioxide, CO₂ produced from the balanced equation.

H₃C₆H₅O₇ + 3NaHCO₃ —> 3CO₂ + 3H₂O + Na₃C₆H₅O₇

Molar mass of H₃C₆H₅O₇ = (3×1) + (12×6) + (5×1) + (7×16) = 192 g/mol

Mass of H₃C₆H₅O₇ from the balanced equation = 1 × 192 = 192 g

Molar mass of CO₂ = 12 + (2 × 16) = 44 g/mol

Mass of CO₂ from the balanced equation = 3 × 44 = 132 g

From the balanced equation above,

192 g of H₃C₆H₅O₇ reacted to produce 132 g of CO₂

Finally, we shall determine the theoretical yield of CO₂. This can be obtained as follow:

From the balanced equation above,

192 g of H₃C₆H₅O₇ reacted to produce 132 g of CO₂.

Therefore,

13 g of H₃C₆H₅O₇ will react to produce = (13 × 132) / 192 = 8.93 g of CO₂.

Thus, the theoretical yield of CO₂ is 8.93 g
