Processes in which matter changes between liquid and solid states are freezing and melting. Processes in which matter changes between liquid and gaseous states are vaporization, evaporation, and condensation. Processes in which matter changes between solid and gaseous states are sublimation and deposition.
Molecular crystals does iodine, dry ice (CO2) , ice and plastic form. It is becuase<span> is that all four are made of nonmetal elements.Which implies any compounds are made up of molecule.</span>
Answer:
C. single replacement
Explanation:
In a single replacement reaction, one atom replaces another.
The general form of a single replacement reaction is: A + Bc ⇒ Ac + B
A + B × c ⇒ B + A × c
↓ ↓ ↓ ↓ ↓ ↓
Fe + Pb(NO₃)₂ ⇒ Pb + Fe(NO₃)₂
Iron switched places with lead so the reaction is a single replacement reaction.
Hope this helps.
I think the correct answer from the choices listed above is option A. It is the salt bridge that balances charges that may build up as reduction and oxidation occur in a voltaic cell. The salt bridge is to <span>maintain charge balance because the electrons are moving from one half cell to the other.</span>
