Answer: D
Explanation:
the atom of the metal loses one electron which becomes delocalised and is attragted by the positive nucleus leading to formation of metallic bond.
<span>chemical is converted into mechanical energy.</span>
Answer:
Sodium chloride will conduct electricity only when it is in a liquid state or in solution, this is because the ions are free to move in this state, allowing them to carry charge and conduct electricity
Explanation:
hope this helped you learned this in 5th grade
Answer is: in chemical reaction with with weak acid, sodium carbonate produce carbonic acid (H₂CO₃), which decomposes into carbon(IV) oxide (fizzy bubbles) and water.
Balanced chemical reaction:
Na₂CO₃ + 2HClO → CO₂(g) + H₂O + 2NaClO.
Chemical decomposition is the separation of a carbonic acid into water and carbon dioxide: H₂CO₃ → CO₂ + H₂O.
Liquids are similar to gases in that they both have <span>no definite shape.</span>
