Which of the conservationists discussed earlier in this unit is
Arte-miy333 [17]

The correct answer is A. The conservationist credited with founding the Wilderness Society is Bob Marshall.

Bob Marshall was an American forester, botanist, traveler, climber, writer and social activist who advocated the preservation of unspoiled wildlife.

 

He actively contributed to the development and adoption of environmental regulations prohibiting the construction of roads in vast federal specially protected natural areas. In 1935 he became one of the founders of the public environmental organization The Wilderness Society and its main sponsor.  

Today Bob Marshall is considered one of the main initiators of the wildlife movement in the United States. Several geographic features are named after him, including the Bob Marshall Wilderness Nature Reserve in Montana and the Marshall Mountain on the Adirondack Ridge.

If excess ammonium sulfate reacts with 20.0g of calcium hydroxide how many grams of ammonia are produced
bagirrra123 [75]
The reaction between ammonium sulfate and calcium hydroxide is given below. 
            (NH₄)₂SO₄ + Ca(OH)₂ --> 2NH₃ + CaSO₄ + 2H₂O
From the balance equation, we can conclude that every 74 g of calcium sulfate reacted with enough amount of ammonium sulfate will yield 34 grams of ammonia. From the given amount,
               (20 g calcium sulfate) x (34 grams ammonia / 74 g calcium sulfate)
                               = <em>9.19 g ammonia</em>

the double bond in ethene is made up of a pi bond and a sigma bond formed by lateral overlap of two p orbitals
Deffense [45]

The unhybridized pz orbitals on each carbon overlap to a π bond (pi).The sigma bond framework of the ethylene molecule is produced by the overlap of hybrid orbitals or by the interaction of a hybrid orbital and a 1s hydrogen orbital.

Each carbon still has its unhybridized pz orbital, though. Sigma bond are typically the only types of single bonding between atoms. One sigma bond and two pi bonds make up triple bonds. One sigma () bond makes up a single bond, one and one pi () bond makes up a double bond, and one and two bonds make up a triple bond.
