<h3>
Answer:</h3>
AgCl + NaNO₃
<h3>
Explanation:</h3>
- The reaction between silver nitrate and sodium chloride is an example of a double displacement reaction.
- In a double displacement reaction compounds or salts reacts and exchange cations or anions to form new compounds or salts.
- In this case, silver nitrate and sodium chloride exchange anions and cations to form silver chloride and sodium nitrate.
- Therefore, the complete reaction is given by;
AgNO3 + NaCl → AgCl + NaNO₃
- But since silver chloride is a precipitate, the reaction may also be an example of a precipitation reaction.

Answer:
The current is reduced to half of its original value.
Explanation:
- Assuming we can apply Ohm's Law to the circuit, as the internal resistance and the load resistor are in series, we can find the current I₁ as follows:

- where Rint = r and RL = r
- Replacing these values in I₁, we have:

- When the battery ages, if the internal resistance triples, the new current can be found using Ohm's Law again:

- We can find the relationship between I₂, and I₁, dividing both sides, as follows:

- The current when the internal resistance triples, is half of the original value, when the internal resistance was r, equal to the resistance of the load.
