How many moles of water are created if 3 moles of hydrogen react completely with excess oxygen?

Chemistry
1 answer:
Alenkinab [10]3 years ago
4 0

Answer:

3.0 moles.

Explanation:

  • It is a stichiometry problem.
  • The chemical reaction of reacting hydrogen with oxygen to produce water is:

<em>H₂ + 1/2 O₂ → H₂O.</em>

  • It is clear that <em><u>1.0 mole of H₂</u></em> reacts with 0.5 mole of O₂ to produce <u><em>1.0 mole of  water</em></u>.
  • The ratio of the reacting hydrogen to the produced water is 1:1.

∴ The number of moles of water created from reacting 3.0 moles of hydrogen completely with excess oxygen = 3.0 moles.

What is the product of reduction of ethyl 4-oxobutanoate with sodium borohydride in ethanol at room temperature for 30 minutes?
zheka24 [161]

The product of reduction of ethyl 4-oxobutanoate with sodium borohydride in ethanol at room temperature for 30 minutes is ethyl 4- hydroxybutanoate .

Sodium borohydride is a relatively selective reducing agent  Ethanolic solutions of Sodium borohydride reduces aldehyde , and ketone , in the presence of acid chloride , ester , epoxide , lactones , acids , nitriles , nitro groups.

The sodium borohydride does not reduce ester group because sodium borohydride is not strong enough and the electrophilicity at carbony carbon of ester is not more as compare toaldehyde , and ketone

The product of reduction of ethyl 4-oxobutanoate with sodium borohydride in ethanol at room temperature for 30 minutes is ethyl 4- hydroxybutanoate .

Define what chemical and radiant energy is
juin [17]
Radiant energy is energy contained in electromagnetic waves. These include visible light, infrared, radio waves, ultraviolet and microwaves. ... Chemical energy is energy stored in chemical bonds between atoms.

Photosynthesis is the transformation of radiant energy to chemical energy. Plants take in water, carbon dioxide, and sunlight and turn them into glucose and oxygen. Called photosynthesis, one of the results of this process is that carbon dioxide is removed from the air.
