Question

question 56 (1 point)
the correct names of ba(no₃)₂ and nahco₃ are:

1. boron nitrate and sodium hydrogencarbonoxygenate
2. barium nitrate and sodium hydrogen carbonate
3. berrylium nitride and sodium carbide
4. barium nitride and sodium carbonate

Explanation:

Step1: Analyze \( \text{Ba(NO}_3\text{)}_2 \)

The cation is \( \text{Ba}^{2+} \) (barium ion), and the anion is \( \text{NO}_3^- \) (nitrate ion). So the compound is named by combining the cation and anion: barium nitrate.

Step2: Analyze \( \text{NaHCO}_3 \)

The cation is \( \text{Na}^+ \) (sodium ion), and the anion is \( \text{HCO}_3^- \) (hydrogen carbonate ion, also called bicarbonate). So the compound is sodium hydrogen carbonate (or sodium bicarbonate).

Now check the options:

• Option 1: Incorrect names (boron instead of barium, wrong anion name).
• Option 2: Matches the correct names (barium nitrate and sodium hydrogen carbonate).
• Option 3: Incorrect (beryllium, nitride, and carbide are wrong).
• Option 4: Incorrect (nitride and carbonate are wrong for the anions).

Answer:

1. Barium nitrate and Sodium hydrogen carbonate
