Answer:
1 - Weak electrolyte
2- Non electrolyte
3- Weak electrolyte
4- Strong electrolyte
Explanation:
A strong electrolyte refers to an electrolyte that decomposes completely in solution. This means that there are more charge carriers in solution when a strong electrolyte is dissolved in water. A strong electrolyte produces a strong glow. LiOH is a strong electrolyte.
A weak electrolyte is not completely dissociated in water. Only a small amount dissociates in water. HF is a weak electrolyte. A weak electrolyte does not produce a bright light.
A non-electrolyte does not dissociate in solution at all hence it does not power a bulb E.g C12H22O11.
D. All of the answers are true
It should be a chemical change
Answer:
Explanation:
Some signs of a chemical change are a change in color and the formation of bubbles. The five conditions of chemical change: color chage, formation of a precipitate, formation of a gas, odor change, temperature change. Or Light is given off, a permanent color change occurs, gas is given off, heat is given off, and a precipitate is formed
