Answer:(16)(2000)m/s=32000m/s
Explanation: A diatomic oxygen has a molar mass of 16
Exothermic releases energy(heat) from the system to the surrounding
endothermic takes energy (heat) from the surrounding to the system
Answer:
Cr(NO₃)₂(s) → Cr⁺²(aq) + NO₃⁻(aq)
Explanation:
A strong electrolyte is a substance that dissolves in water, dissociating in its ions, and making the solution an electric conductor. The conduction will happen because of the presence of the ions. The dissociation will be complete and irreversible.
The chromium (II) nitrate is formed by the cation chromium (II), Cr⁺², and the anion nitrate, NO₃⁻, so it is the compound Cr(NO₃)₂.
Cr(NO₃)₂(s) → Cr⁺²(aq) + NO₃⁻(aq)
