Answer:
The answer is C. Simple cubic, face-centered cubic, body-centered cubic
Explanation:
Simple cubic: Containing one lattice point on each corner of the cube with each atom at the lattice point shared equally between the eight adjacent corners.
Body-centered cubic: having one lattice point in the center of the unit cell in addition to the eight corners. i.e 
Face-centered cubic: having lattice points on the faces of the cube giving exactly one half contribution.
Answer:
The major product is 2-methyl-2-pentene [ CH₃-CH₂-CH=C(CH₃)₂ ] and a minor product 2-methyl-1-pentene [ CH₃-CH₂-CH₂-C(CH₃)=CH₂ ].
Explanation:
Dehydration reaction is a reaction in which a molecule loses a water molecule in the presence of a dehydrating agent like sulfuric acid (H₂SO₄).
<u>Dehydration reaction of 2-methyl-2-pentanol</u> gives a major product 2-methyl-2-pentene and a minor product 2-methyl-1-pentene.
CH₃-CH₂-CH₂-C(CH₃)₂-OH (2-methyl-2-pentanol)→ CH₃-CH₂-CH=C(CH₃)₂ (2-methyl-2-pentene, major) + CH₃-CH₂-CH₂-C(CH₃)=CH₂ (2-methyl-1-pentene, minor)
<u>Since more substituted alkene is more stable than the less substituted alkene. So, the trisubstituted alkene, 2-methyl-2-pentene is more stable than the disubstituted alkene, 2-methyl-1-pentene.</u>
<u>Therefore, the trisubstituted alkene, 2-methyl-2-pentene is the major product and the disubstituted alkene, 2-methyl-1-pentene is the minor product.</u>
Answer:
I think it is A
Explanation:
A.They study how to make plants produce certain chemicals
Answer:
6.75 moles of Ba(NO₃)₂.
Explanation:
The balanced equation for the reaction is given below:
3BaCl₂ + 2Al(NO₃)₃ —> 3Ba(NO₃)₂ + 2AlCl₃
From the balanced equation above,
2 moles of Al(NO₃)₃ reacted to produce 3 moles of Ba(NO₃)₂
Finally, we shall determine the number of mole of Ba(NO₃)₂ produced by the reaction of 4.25 moles of Al(NO₃)₃. This can be obtained as illustrated below:
From the balanced equation above,
2 moles of Al(NO₃)₃ reacted to produce 3 moles of Ba(NO₃)₂.
Therefore, 4.25 moles of Al(NO₃)₃ will react to produce = (4.50 × 3)/2 = 6.75 moles of Ba(NO₃)₂.
Thus, 6.75 moles of Ba(NO₃)₂ were obtained from the reaction.
