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.

How does One determine number of electron domains in molecul or ion
Answer:
The number of electron domains in a molecule or ion is the number of bonds (double and triple bonds count as one domain) plus the number of nonbonding (lone) electron pairs.

What effect does salt have on a marshmallow?
Answer:
The original marshmallow was named for the inclusion of marshmallow root in the recipe. The roots and leaves of the marshmallow plant contain mucilage, a slimy-textured demulcent best known for its use as a homeopathic cough suppressant. Marshmallow root is considered to be soothing and mildly antimicrobial. It has long been used as an herbal treatment for minor digestive issues and skin irritations, although its use in the creation of its namesake confection has long since fallen by the wayside.

A sample of H2 gas (12.28 g) occupies 100.0 L at 400.0 K and 2.00 atm. A sample weighing 9.49 g occupies ________ L at 353 K and 2.00 atm.
Considering the ideal gas law, a sample weighing 9.49 g occupies 68.67 L at 353 K and 2.00 atm.
Ideal gases are a simplification of real gases that is done to study them more easily. It is considered to be formed by point particles, do not interact with each other and move randomly. It is also considered that the molecules of an ideal gas, in themselves, do not occupy any volume.
An ideal gas is characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them constitutes the ideal gas law, an equation that relates the three variables if the amount of substance, number of moles n, remains constant and where R is the molar constant of the gases:
P× V = n× R× T
In this case, you know:
P= 2 atmV= ?n= [tex]9.49 gramsx\frac{1 mole}{2 grams} = 4.745moles[/tex] being 2g/mole the molar mass of H2, that is, the amount of mass that a substance contains in one mole.R= 0.082 [tex]\frac{atmL}{molK}[/tex]T= 353 KReplacing:
2 atm× V = 4.745 moles× 0.082[tex]\frac{atmL}{molK}[/tex]× 353 K
Solving:
V = (4.745 moles× 0.082[tex]\frac{atmL}{molK}[/tex]× 353 K)÷ 2 atm
V= 68.67 L
Finally, a sample weighing 9.49 g occupies 68.67 L at 353 K and 2.00 atm.

Blood has a mass-volume percent of NaCl of 0.9%. What mass (g) of NaCl is present in a liter of blood
The mass (g) of NaCl that is present in a liter of blood is 0.347g.
HOW TO CALCULATE MASS:
The mass of a substance can be calculated by multiplying the decimal mass-volume of the substance by its molar mass. According to this question, Blood has a mass-volume percent of NaCl of 0.9%. This means that 0.9/100 = 0.009g of NaCl is present in each 100g of blood. Molar mass of NaCl = 23 + 35.5 = 38.5g/molMass of NaCl in a liter of blood = 38.5 × 0.009Mass of NaCl in a liter of blood = 0.347g of NaCl. Therefore, The mass (g) of NaCl that is present in a liter of blood is 0.347g.Learn more at: https://brainly.com/question/15743584?referrer=searchResults

what is distillation used to seperate
Distillation is used to separate liquids from nonvolatile solids as in separation of alcoholic Liquors from fermented materials or in the separation of two or more liquids having different boiling points as in the separation of gasoline Carrison and lubricating oil from crude oil
Answer: It is used to separate a solvent from a solute.
Explanation:
the apparatus in the figure below is used for the electrolysis of water. hydrogen and oxygen gas are collected in the two inverted burets. an inert electrode at the bottom of the left buret is connected to the negative terminal of a 6 v battery, whereas the electrode in the buret on the right is connected to the positive terminal. a small quantity of sodium carbonate is added to speed up the electrolytic reaction.
At the left side; the balanced half equation is:
[tex]\mathbf{2H_2O _{(l)} + 2e^- \to H_{2(g)} + 2OH^{-}_{(aq)}}[/tex]
At the right side, the balanced half equation is:
[tex]\mathbf{4OH^-_{(aq)} \to O_{2(g)} + 2H_2O_{(l)} + 4e^-}[/tex]
The objective of this question is to determine the balanced half-reaction for the electrodes on the left and the right side.
A half-reaction is an oxidation-reduction reaction part of a redox reaction where we make sure both half-reactions are balanced by multiplication of the reactions with appropriate numbers in order to have an equal number of electrons.
According to the given information:
The overall cell reaction can be expressed as:
[tex]\mathbf{H_2O_{(l)} \to H_{2(g)} + \dfrac{1}{2}O_{2(g)}}[/tex]
At the left side; the balanced half equation can be expressed as:
[tex]\mathbf{2H_2O _{(l)} + 2e^- \to H_{2(g)} + 2OH^{-}_{(aq)}}[/tex]

When gravity is the only force acting on an object, the object is said to be in__.
How does calculating the kinetic energy of an object at different velocities help understand the relationship between kinetic energy and velocity?
Answer:
Kinetic energy depends on the velocity of the object squared
Explanation:
Kinetic energy depends on the velocity of the object squared. This means that when the velocity of an object doubles, its kinetic energy quadruples. ... Kinetic energy must always be either zero or a positive value. While velocity can have a positive or negative value, velocity squared is always positive.

To solve for number one we must follow these steps:
m = 703.55 g − 345.8 g
m = 357.75 g
Then we solve for the density-
d = 357.75 g / 225 mL
d = 1.59 g/mL
Answer for number 5) 1.59 g/mL
Density= Mass/Volume
therefor- Mass = 65.14g and Volume = 35.4mL
Density = 65.14g/35.4 mL = 1.84 g/mL
Answer for number 6) 1.84 g/mL
Question 7-
g = (0.8765 g/mL)(250.0 mL) = 219.1 g
Answer: 219.1 g
Question 8-
Density = mass/volume
Mass = 1587g
4.5cm x 5.2cm x 6cm = 140.4 cubic-cm
Volume = 140.4 cubic-cm
Mass/volume = 1587/140.4 = 11.3 g/cm^3
Answer: 11.3 g/cm^3
Question 9:
First calculate the volume of iron
49.10mL − 45.50mL = 3.60mL
Density = mass/volume;
density = 28.5g/3.60 mL= 7.92 g/mL
Answer: 7.92 g/mL
Question 10:
Volume = 2500.0g / 10.5g/cm3 = 238.095cm^3
Now we round up the answer to 238cm^3
Answer: 238cm^3
