Answer:
Red, orange, yellow, green, blue, indigo, violet.
Explanation:
The atomic number is equal to the number of protons
Answer:
<em>Step 1: Write the balanced chemical equation with the states first:</em>
Ca(OH)₂ (aq) + 2NH₄Cl (aq) → CaCl₂ (aq) + 2NH₃ (g) + 2H₂O (l)
<em>Step2: Write the complete ionic equation, break only the aqueous ones only :</em>
Ca²⁺ + 2OH⁻ + 2NH₄⁺ + 2Cl⁻ → Ca⁺² + 2Cl⁻ + 2NH₃ (g) + 2H₂O (l)
<em>Step 3: cancel the spectator ions ( the ions which stay the same like calciumn and chlorine ions here)</em>
<h2> 2OH⁻ + 2NH₄⁺ → 2NH₃ (g) + 2H₂O (l)</h2>
