Question

reflect on the laboratory experiment.

which substances were acids?

chlorine

cinnamaldehyde

sodium chloride

sodium bicarbonate

how good were your predictions in the warm - up?
0 out of 4 right
1 out of 4 right
2 out of 4 right
3 out of 4 right
4 out of 4 right

Explanation:

1. For the first question, the checkmarks next to "sodium chloride" and "sodium bicarbonate" indicate these are the ionic substances.
2. For the second question, the table shows that 4 out of 4 properties (crystalline structure, solubility in water, conductivity) match the ionic substance characteristics for the two marked compounds, meaning all predictions were correct.

Answer:

1. sodium chloride

sodium bicarbonate

1. 4 out of 4 right
