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

Vlada [557]

Answer:

the mass required to inflate a 72 L bag is 191.491 g

Explanation:

reaction:

  • 2 NaN3 ↔ 2 Na + 3 N2

conditions:

  • V = 72.0 L
  • STP: P = 1 atm  ∧ T = 298 K

gas law:

  • PV = RTn
  • R = 0.082 atm * L / K * mol

⇒ n = PV / RT

⇒ n = ((1 atm) * ( 72.0 L)) / (0.082 atm*L / K*mol) * (298 K)

⇒ n = 2.946 mol

⇒ m = n * Mw = ( 2.946 mol ) * ( 64.99 g/mol)

⇒ m = 191.491 g

Electrophilic addition of bromine, Br2, to alkenes yields a 1,2-dibromoalkane. The reaction proceeds through a cyclic intermedia
Taya2010 [7]

Answer:

See explanation and image attached for details

Explanation:

The reaction involves the heterolytic fission of the Br-Br bond in the bromine molecule to yield a bromine cation which attacks the but-1-ene to form a cyclic intermediate called the brominium ion. The bromine anion must now attack from the opposite face of the brominium ion due to steric clashes to form a product of a 1,2-dibromoalkane having the anti- stereochemistry.
