Answer:
es esto OH−
Explanation:
el hidróxido es hidrógeno unido covalentemente al oxígeno. Es un anión y tiene carga negativa.
The tool or instrument which is used to measure an object’s mass is electronic balance
Mass is a fundamental quantity
<h3>What is fundamental quantities?</h3>
Fundamental quantities can be defined as those physical quantities which forms the basic unit of measurement. They are the quantities upon which other quantities and units are derived from.
Mass is measured in kilograms (kg)
Other examples of fundamental quantities apart from mass are as follows:
- Length
- Time
- Amount of substances
- Luminous intensity
- Temperature
- Magnetic flux
So therefore, the tool or instrument which is used to measure an object’s mass is electronic balance

Cerebrospinal fluid of the central nervous system and synovial fluid of joint capsules are both examples of <u>extracellular </u><u>fluid</u>
- Extracellular fluid called cerebrospinal fluid is present throughout the CNS
- It acts as a protective layer for CNS ftom injury and shock
- Cerebrospinal fluid is clear, colorless fluid produced by the choroid plexus.
- It surrounds the brain and spinal cord.
Synovial fluid is a viscous solution found in cavities of synovial joints. The principal role of synovial fluid is to reduce friction between articular cartilages of synovial joints during movement.
- Synovial fluid is a small component of transcellular fluid component of extracellular fluid.

It is not correct to say " a molecule of salt " because salt is a compound.
Explanation:
- As we know a molecular bond is present in each molecule.
- Salt (NaCl) is considered as a compound because it is made up of two types of elements that are sodium as well as chlorine.
- On the other hand it is not considered as a molecule as it is not holding an ionic bond.
- As a result we can name it as an ionic compound. Hence it is not considered as a molecule of salt.
