Answer:
Gains Kinetic Energy
Explanation:
Kinetic energy (KE) is the energy inserted on the object in motion. Having gained this energy enerted upon, the body maintains this kinetic energy unless its speed changes.
First, we write the reaction equation:
NiCO₃ + 2HBr → NiBr₂ + H₂CO₃
Now, writing this in ionic form:
NiCO₃ + 2H⁺ + 2Br⁻ → NiBr₂ + 2H⁺ + CO₃⁻²
(NiCO₃ is insoluble so it does not dissociate in to ions very readily)
Overall equation:
NiCO₃ + 2Br⁻ → NiBr₂ + CO₃⁻²
Answer:
Explanation:
The name of the compound is:
Al(NO₃)₃ is Aluminium nitrate
Aluminium nitrate is an ionic compound formed when Al loses 3 valence electrons to the nitrate.
