Answer:

Option b) Carbon dioxide and oxygen

Explanation:

Thinking process:

Sodium hydroxide is an alkaline solid substance. It reacts with acids to form salts and water. In this case, it is known that carbon dioxide, CO₂, is an acidic gas. Therefore, the reaction gives a salt that results in carbon dioxide being absorbed by the sodium hydroxide.

Heated copper is an excellent removal of oxygen. This is because monovalent copper, Cu, has a deep binding affinity for oxygen.  Hence the the oxygen trapped by the atom.

One problem with elimination reactions is that mixtures of products are often formed. For example, treatment of 2-bromo-2-methyl
NikAS [45]

Answer:

Structures are given below.

Explanation:

  • Treatment of 2-bromo-2-methylbutane with KOH in ethanol will give elimination of HBr through E2 mechanism.
  • H atoms adjacent to Br will be eliminated.
  • 2-bromo-2-methylbutane has two possible adjacent H atoms that can be eliminated giving mixture of products.
  • Product of this elimination reaction is alkene. Here saytzeff fule is followed during elimination. So most substituted alkene will be major product.
  • Structure of alkenes are given below.

When doing a titration what is the equivalency point of the neutralization reaction?
KengaRu [80]
The equivalency point is at the point of the titration where the amount of titrant added neutralize the solution. When it’s a strong acid strong base titration, the equivalence point will be 7. When it is a weak acid strong base, the equivalence point it more basic (the exact number depends on what acid and base you use). And when it is a strong acid weak base, the equivalence number is more acid (the exact number depends on what acid and base you use). Hope this helps!
