Answer:

Valence electrons are involved in Reaction B but not in Reaction A.

Explanation:

The description of reaction A in which protons are lost or gained by the atom of the element is a nuclear reaction. In nuclear reactions, the nucleons which are the protons and neutrons drives the reaction. No valence electrons in the orbiting shells are involved in this kind of reaction. During this type of reaction, an atom changes it identity to that of another.

Reaction B in which no identity change occurs is a chemical reaction. In chemical reactions bonds are formed by the atoms using the valence electrons that orbits round the central nucleus. The atoms remain the same but it chose to attain stability and an inert configuration by losing or gaining electrons.

Answer:

  1. Compress
  2. Fixed
  3. Melts
  4. Melting Point
  5. Freezing Point
  6. High
  7. Crystalline
  8. Lattice
  9. Unit cell
  10. Amorphous solids

Explanation:

Solids tend to be dense and difficult to <u>compress.</u>

They do not  flow or take the shape of their containers, like liquids do, because  the particles in solids vibrate around <u>fixed</u> points.

When a solid  is heated until its particles vibrate so rapidly that they are no longer  held in fixed positions, the solid <u>melts</u>.  

<u>Melting point</u> is the  temperature at which a solid changes to a liquid. The melting and <u>freezing point</u>  of a substance are at the same temperature.

In general,  ionic solids tend to have relatively <u>high</u>  melting points, while  molecular solids tend to have relatively low melting points.

Most  solids are <u>crystalline</u>

The particles are arranged in a pattern known  as a crystal <u>lattice</u>

The smallest subunit of a crystal lattice is the <u>unit cell</u>  

Some solids lack an ordered internal structure   and are called <u>amorphous solids.</u>

The temperature of a 10.0 L sample of nitrogen in a sealed container is increased from 22°C to 202°C, while its pressure is incr
stiks02 [169]

Answer:

The new volume is 5.37 L

Explanation:

Step 1: Data given

Initial volume = 10.0 L

Initial temperature = 22.0 °C

Initial pressure = 1.00 atm

Final temperature = 202 °C

Final pressure = 3.00 atm

Step 2: Calculate final volume

(P1*V1)/T1  = (P2*V2)/T2

⇒ with P1 = The initial pressure = 1.00 atm

⇒ with V1 = The initial volume = 10.0 L

⇒ with T1 = The initial temperature = 22 °C = 295 Kelvin

⇒ with  P2 = The final pressure = 3.00 atm

⇒ with V2 = The final volume = TO BE DETERMINED

⇒ with T2 = The final temperature = 202 °C = 475 Kelvin

(1.00 * 10.0) / 295 = (3.00 * V2) / 475

10 / 295 = 3V2/ 475

3V2 = 4750/295

V2 = 5.37 L

The new volume is 5.37 L
