boiling point (intensive): the temperature at which a substance boils.
melting point (intensive): the temperature at which a substance melts.
Decomposition is the example of a reaction in which hydrogen and oxygen are produced by running an electric current through water.
Decomposition of water through electrolysis of water into oxygen and hydrogen gas due an electric current passed through water. when an electric current is passed through water, oxygen gas is being produced at the anode and hydrogen gas is produced at the cathode.
The state of matter is liquid.
Answer:
a pencil being sharpened
freezing water
boiling water
Explanation:
a physical change doesn't change the chemical structure of an object. That is why the other 2 are wrong
Answer:
This question appears incomplete
Explanation:
However, it should be noted that addition of soluble salts generally lowers the freezing point of water hence after the addition, water will no longer freeze at 0°C but lower.
Soluble salts tend to form more ions in water, it is these ions that are responsible for interfering with the hydrogen bonds hence lowering the freezing. Thus, (since each bag are of the same weight) <u>the bag that contains the salt that ionizes more in water will lower the freezing point by the greatest amount</u>.
NOTE: Different weight of the salts could lead to more ions been formed in the water by some salts as against the other.
