<span>The
Pair Of Compounds that Are Isomers are CH3COCH3 and CH3CH2CHO. The answer is
number 4. Isomers have the same formula but different structures. In number 4,
both compounds contains three carbon atoms, one oxygen and 6 hydrogen atoms
that makes them isomers.</span>

Answer:
1) Sound waves are stores as electrical signal in the digital recording.
2) the electrical signal of the digital recording is transcribed and sent to the voice coils.
3) the voice coil changes this electrical signal into varying magnetic fields.
4) The magnetic field pushes and pulls the diaphragm of the speakers.
5) the pushing and pulling of the diaphragm generates sound waves in the speaker.
Hydrogen ions in acids and hydroxide ions in bases
Answer: E
Explanation:
The lattice energy is the energy change when one mole of a crystal is formed from its components ions in its gaseous sate
Therefore lattice energy = heat of Sublimation+ ionization energy +electron affinity-(heat of formation)
Therefore lattice Energy = 109 +495 -328 +570.
Lattice energy = --923kjmol-1
