A Scottish scientist Graham, Thomas formulated Graham's law of effusion or simply Graham's law. This law states that rate of gas 1 over gas 2 is equal to the square root of the molar mass of gas 2 over <span>he square root of the molar mass of gas 1. Since the molar mass of Neon is 4, the answer is then 8.16 g/mol</span>

- Explain how ionic bonds, covalent bonds, and metallic bonds each form and how.
-Dominant- [34]

Answer:  -Ionic bonds form when one atom provides electrons to another atom. Covalent Bonds: Covalent bonds form when two atom shares their valence electrons. Metallic Bonds: Metallic bonds form when a variable number of atoms share a variable number of electrons in a metal lattice.

-Covalent Bonds.

Covalent Compounds. Contain no metals and no ions. Covalent compounds contain nonmetals only.

Example:

Ionic Compounds. A metal with a non-metal. Doesn't use prefixes for naming. Name the metal and change the nonmetal ending to -ide.

Explanation: Ionic bonds form when a nonmetal and a metal exchange electrons, while covalent bonds form when electrons are shared between two nonmetals. An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions.

What does the total thermal energy of a system depend on?
IrinaVladis [17]

Answer:

The correct answer is - temperature, state of molecules, and the number of molecules.

Explanation:

The total thermal energy of a system or the total internal energy of a system solely depends on three major aspects of the system's or objects that are the number of molecules or atoms in the system, the temperature of the system, and the state or arrangement of the molecules of the system. More the molecules or atoms present in a system at a particular temperature higher the total thermal energy the system has.

Thus, the correct answer is - temperature, state of molecules, and the number of molecules.

(plsss help meh.) Describe how you could find the density of a gold crown.
Lynna [10]

Answer:

Below! ;)

Explanation:

The formula for finding density is:

Mass/Volume

So for example I have a cube, it has a mass of about 20 grams (not weight) and it's dimensions are about an inchxinchxinch. So basically it is a 20 gram cubic inch cube.

So to find it's density I have to divide mass(=20)/Volume(=1 inch^3). or simplified, 20 ÷ 1 = 20

So the density of my cube is 20..

Hope this helps!

Have a nice day!
