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
The rapid motion and collisions of molecules with the walls of the container causes pressure.
Answer:
<h2>28,800 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volume
From the question we have
mass = 24 × 1200
We have the final answer as
<h3>28,800 g</h3>

Answer:
pluto is considered a dwarf planet because it did not meet the three criteria the IAU uses to define a full sized planet
Explanation:
If you are talking about bonds they are influenced by electronegativity and how many valence electrons they have.
