Question at position 3
Students in a chemistry class added sodium chloride to silver nitrate; both of these substances were colorless. However, the reaction produces a white cloudy product. The chemical equation for this is: AgNO3(aq) + NaCl(aq) → AgCl(s) + NaNO3(aq). What type of reaction is this?

The reaction you described is a double displacement reaction (also known as a double replacement reaction). In this type of reaction, the anions and cations of two different compounds exchange places to form two new compounds. In your case, sodium (Na) and silver (Ag) switch partners, leading to the formation of solid silver chloride (AgCl) and aqueous sodium nitrate (NaNO3).
