The hot fuel particles reacted with water and caused a steam explosion, which lifted the 1,000-metric-ton cover off the top of the reactor, rupturing the rest of the 1,660 pressure tubes, causing a second explosion and exposing the reactor core to the environment.

Answer 2

Answer: C. Formation of a precipitate

Explanation:

Silver nitrate and sodium chloride solutions are both colourless. When they react, they produce white precipitate and a colourless solution. The chemical sodium nitrate is colourless and water soluble. When you gently add one chemical to another, drop by drop, you will notice a white precipitate forming in the solution. When one chemical is instantly added to another, precipitate is generated. When aqueous AgNO3 and aqueous NaCl compounds are mixed together, there is a good likelihood that a white precipitate will form if the original silver nitrate and salt chloride concentrations are high. That instance, the reaction between AgNO3 and NaCl is a precipitation reaction.
