Answer:
An atom that gains a negative electron, it becomes a negative ion. If it loses an electron it becomes a positive ion. Picture 1.8 Some atoms lose electrons and become positive ions. Others gain electrons and become negative ions.

Answer:
C) As a gas is heated, the pressure decreases.
Explanation:
From the choices given, the statement that "as a gas is heated, the pressure decreases is false".
When gases are heated, their molecules expands and the volume of the gas increases. In a fixed container, the pressure of the gases will also increases.
- Gases lack internal cohesion and very weak to no intermolecular forces binding them together.
- When they are subjected to heat, they gain more energy(kinetic energy) which causes them to begin to spread out.
- Thus, they take up even more space allowing volume to increase appreciably.
N2o5 would diffuse more slowly
CH3OCH3 and C2H5OH are isomers. They have same molecular formula. But with another formation.
Answer:
Explanation:The buffer is a mixture of ammonia (NH3) and ammonium (NH4+). ... Since ammonia (NH3) is a weak base, it will have a pH above 7 and since ammonium (NH4+) is a weak acid, it will have a pH below 7. Ammonia (NH3) is a weak base and ammonium (NH4+) is a weak acid. Ammonia (NH3) is the conjugate base of ammonium (NH4+).
