Answer:
Acid solutions will be those which lights up a bulb when a circuit is connected through them.
Explanation:
Acid solutions such as HCl and HNO3 are polar in nature and permits the flow of electricity through them. Whereas non-polar solutions like ethanol and glucose solution will not allow the flow of electricity through them.
Therefore, when an electric circuit is completed by dipping the nails connected to a battery and a bulb into the different solutions, the lighting up of the bulb indicates which solutions are acids.
Answer:
Hydrogen bonding
Explanation:
Water is a compound found readily in nature. It is made up of interatomic forces of covalent bonds that connects the hydrogen and oxygen bonds together in a definite ratio.
- The intermolecular forces are responsible for the physical properties of substances.
- These forces allows a compound to behave in certain ways.
- In water, the intermolecular bonding present are the very strong hydrogen bonds.
- For this bond type, the hydrogen of one water molecule is firmly attached to the oxygen of another water molecule.
- The bonds are very strong forces.
