Answer:
An acid is a substance that donates hydrogen ions. Because of this, when an acid is dissolved in water, the balance between hydrogen ions and hydroxide ions is shifted. Now there are more hydrogen ions than hydroxide ions in the solution. This kind of solution is acidic.

Answer:
Ion-dipole forces
Explanation:
Na⁺ is a cation, that is, an ion with a positive charge.
NH₃ has polar covalent bonds (due to the difference in electronegativity between nitrogen and hydrogen). According to the VESPR theory, it has a trigonal pyramidal shape with a lone pair. As a consequence, it has a net dipole moment and the molecule is polar.
The intermolecular forces between Na⁺ (ion) and NH₃ (dipole) are ion-dipole forces.
Answer: Option (B) is the correct answer.
Explanation:
It is known that flow of electrons is known as current. Also, we know that electrons carry a negative charge.
Therefore, when parallel wires carrying current in the same direction then due to the same charge there will be repulsion between the electrons.
Thus, we can conclude that Ampere showed that parallel wires carrying current in the same direction would repel each other.
I believe the answer is surface
Hope this helps :3
After 3 days = 500g becomes 250g
After 6 days = 250g becomes 125g
After 9 days = 125g becomes 62.5g
After 12 days = 62.5g becomes 31.25g
After 15 days = 31.25g becomes 15.625g
After 18 days = 15.625g becomes 7.8125g
After 18days, you would have about 7.813g left.
