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.
What is chemical Compound?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.

The density of gold is 19. 3 g/cm3. What is the volume of a 13 g gold nugget? (Density: D = ). 25 cm3. 67 cm3 1. 48 cm3 2. 50 cm3.
Answer:
0.67 cm³Explanation:
The volume of a substance when given the density and mass can be found by using the formula
[tex]volume = \frac{mass}{density} \\[/tex]
From the question
mass = 13 g
density = 19.3 g/cm³

Pls help me!! Explain how the N:Z ratio can help predict the type of radiation Zr-85 and Zr-95 emit.
No links pls
Based on N:Z ratio, Zr-85 is expected to decay by positron emission. Zr-95 is expected to emit beta particles in a beta decay.
The N:Z ratio determines the stability of a nucleus. If a nucleus has N:Z ratio >1.5 or <1.0, such a nucleus is unstable and will undergo radioactive decay. The aim of such a decay is to attain a favorable N:Z ratio.
For Zr -85, the N:Z ratio is 1.1 while the N:Z ratio of Zr-95 is 1.4. Zr -85 is expected to decay by positron emission which increases the N:Z ratio. For Zr-95, the nucleus tends to undergo processes that decrease the N:Z ratio such as beta emission.

In your own words, what is the conservation of mass?
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).

which elements from the periodic table are the least reactive
Noble gases are the least reactive of all elements. That's because they have eight valence electrons, which fill their outer energy level. This is the most stable arrangement of electrons, so noble gases rarely react with other elements and form compounds.
Group 18; The Noble Gases contains the elements on the periodic table that would be the least reactive out of all the elements. So, this include any gas element, such as helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson (Og). Hence, if you have the options:
(The Option in Bold is Correct)
O the group with fluorine at the topO the group with carbon at the topO the group with helium at the topO the group with hydrogen at the top-----------------------------

B) Conversation of matter is not observed because of some of the atoms are converted into energy in the reaction.
C) Conservation of matter is observed because there are the same number of each atom on both sides of the reaction.
D) Conservation of matter is not observed because there are different numbers of molecules in the reactants and the products.
Answer: b/c
Explanation:
what are the uses of the periodic table
Answer:
In today's world, the periodic table is very valuable for both students and scientists since it allows them to forecast the sorts of chemical reactions in which a specific element is likely to engage. Rather than memorizing facts and figures for each element, students and scientists can learn a great deal by simply looking at the table. They can learn about an element's reactivity, whether it is likely to conduct electricity, whether it is hard or soft, and many other characteristics by simply looking at the table.
Groups are made up of elements that are in the same column as one another and have attributes that are comparable to one another. If we look at the first column (the alkali metals), for example, we see that they are all metals that have a 1+ charge in reactions, react quickly with water and combine easily with nonmetals.
Periods are made up of elements that are arranged in a row next to one another and have the same maximum unexcited electron energy level as one another.
The periodic table also has the advantage of providing all the information you need to balance chemical processes at a glance, which is a very valuable feature. The atomic number and, in most cases, the atomic weight of each element are included in the table. The group of an element indicates the characteristic charge of that element.

Which molecule has the same empirical formula as molecular formula?
A. CH3COOH
B. C2H5OH
C. C2H4
D. C4H10
and what is the working
the answer is C ( i think )
The correct statement which has the same empirical formula as molecular formula is "CH3COOH".
What is empirical formula?A chemical compound's empirical formula is a representation of the simplest whole number ratio between its constituent parts.
What is molecular formula?The molecular formula is a depiction of the compound's actual whole number ratio between its constituent parts.
To put it another way, molecular formulas tell you how many atoms of each element are in a compound, whereas empirical formulas tell you the simplest or most reduced ratio of components.
Acetic acid has the molecular chemical formula CH3COOH. In the order C: H: O, the true whole number ratio is 2: 4: 2. In the order C: H: O, the smallest simple whole number ratio is 1: 2: 1. As a result, acetic acid's empirical formula is CH2O.
Hence, the correct option is A.

When the metal was added to the calorimeter, some of the water splashed out. How would the loss of water in the Styrofoam cup affect the final temperature
The final temperature of the cup may be less than accurate thereby affecting the entire results of the experiment carried out using the cup.
A styrofoam cup is an insulated material. A styrofoam cup prevents heat gain or looses from the cup. Heat is gained by the water inside the styrofoam cup. The cup prevents exchange of energy with the environment.
When water is lost from the styrofoam cup, the final temperature of the cup may be less than accurate thereby affecting the entire results of the experiment carried out using the cup.
