N76 [4]

Answer + Explanation:

1. The different ways tectonic plates move in relation to each other are:

        convergent (where plates move into one another)  

        divergent (where plates move apart)

        transform (where plates move sideways in relation to each other)

2. Convergent plate boundaries can result in:

       earthquakes, volcanoes, and the formation of mountains.

The Himalaya Mountains are the result of convergent plate boundaries.

3. Landforms that are a result of divergent boundaries are rift valleys and mid-oceanic ridges.

        Locations where this occurs are:  Mid-Atlantic Ridge, Red Sea Rift, Baikal Rift Zone

, East African Rift, East Pacific Rise,  Gakkel Ridge, Galapagos Rise, and Explorer Ridge.

4. Transforming plate boundaries results in shallow earthquakes, large lateral displacement of rock, and a broad zone of crustal deformation.

  A location where this occurs is: San Andreas Fault in western California

Answer:

160.3g

Explanation:

We know the equation:

No of moles = mass ÷ Mass of element

We need to find the mass, so make mass the subject of the formula.

Mass = No. of moles × mass of element

Mass = 5 × 32.06

Mass = 160.3g

The number of electrons in the outermost principal energy level of a chlorine atom is
Hitman42 [59]

Answer:

seven electrons

Explanation:

Chlorine is present in group seventeen of periodic table. It is halogen element. All halogens have seven electrons in outer most valance shell.

The require only one electron to gain the stable electronic configuration or to complete the octet.

Electronic configuration of chlorine:

Cl₁₇ = 1s² 2s² 2p⁶ 3s² 3p⁵

Abbreviated electronic configuration:

Cl₁₇ = [Ne] 3s² 3p⁵

Properties of chlorine:

1. it is greenish-yellow irritating gas.

2. its melting point is 172.2 K

3. its boiling point is 238.6 K

4. it is disinfectant and can kill the bacteria.

5. it is also used in manufacturing of paper, paints and textile industries.
