What can you infer about aspirin’s ester group?
Reil [10]

Answer:

Option B, aspirin’s ester group provides greater digestibility to aspirin

Explanation:

Aspirin ester group has three parts

  1. carboxylic acid functional group (R-COOH)
  2. ester functional group (R-O-CO-R')
  3. aromatic group (benzene ring)

Aspirin is a weak acid and hence it cannot dissolve in water readily. The reaction of Aspirin ester group with water is as follows -

aspirin

(acetylsalicylic acid) + water → salicylic acid + acetic acid

(ethanoic acid)

Aspirin passes through the stomach and remains unchanged until it reaches the intestine where it hydrolyses ester to form the active compound.

Copper atoms are used to produce pennies. The copper atoms in pennies share many electrons. Pennies contain
kaheart [24]

Answer:

Metallic bonds

Explanation:

Metallic bonds joins atoms of metals and atoms of alloys together. The copper used in making pennies is a metallic substance so it contains metallic bonds.

  • The formation of this bond type is predicated on the large atomic radius, low ionization energy and large number of electrons in the valence shell.
  • The bond is an attraction between the positive nuclei of all closely packed atoms in the lattice and the electron cloud.
  • The electron cloud is jointly formed by all the atoms by losing their outermost shell electrons.

This way the bond in pennies are metallic in nature.

What is the bond angle between the hydrogen atoms in an ammonia (NH₃) molecule?
dimulka [17.4K]
There are 4 electron pairs (3 bonding and 1 lone pair) so the angle is 107 degrees. The 4 electron pairs are repelled to give a tetrahedral arrangement but the molecule has a pyrimidal shape due to the lone pair.

Chemistry help please! 15 points!
Scilla [17]
Catalytic Converter is the correct answer. Toxic gases are produced in the combustion reaction of an engine, and when this gas adheres to the converter, it’s chemically transmuted into something that’s harmless.
