Answer:
Ammonia is an Arrhenius base and a Brønsted-Lowry base.
Explanation:
An Arrhenius base is any substance which, when it is dissolved in an aqueous solution, produces hydroxide (OH^-), ions in solution. An aqueous solution is a solution that has water present in it.
A Bronsted-Lowry base is a substance that accepts a proton, that is, a hydrogen ion (H^+).
Looking at the equation above, ammonia satisfies both characteristics. We can see that when ammonia is dissolved in water, hydroxide ions is produced in the solution. Hence it is an Arrhenius base. Similarly, the hydroxide ion is formed when ammonia accepts a proton. This is a characteristic of a Brownstead-Lowry base. Hence ammonia is both an Arrhenius base and a Brownstead-Lowry base.
Answer:
the time required for one half of a sample of a radioisotope to decay
Answer:
3) Ionic
Explanation:
The solid formed when a bond occurs between magnesium and oxygen is an ionic bond. This bond type occurs between a metal and non-metal.
- Magnesium is the metal
- Oxygen is the non - metal
- Due to the large electronegativity difference between the two species, the metal loses electrons which the non-metal oxygen gains
- They both complete their octet and electrostatic attraction leads to the formation of ionic bonds.
Answer:
Light
Explanation:
1 They were not albe to see at night because it was dark so the lack of light caused them to use echolocation.
Hope this helps
A bulk property is also an intensive property, meaning that it is a physical property that does not depend on the size of the system. examples of bulk properties are color, density, melting/boiling point, pressure, and solubility.
Based on your lists, choice d contains all bulk properties: boiling point, surface tension, vapour pressure.
