The answer is C.
the ice is changing its state of matter but not its composition. it is still water, you just have to freeze it up again.
hope this helps!
Dissolution means to make the compound apart, So when we have ionic compounds like NaI which has metal and non-metal ions, It separates into parts of positive ions and negative ions. After we separate this compound apart we will put the charge of each on above its symbol and then start to balance the equation of the dissolution.
So the dissolution equation of NaI is:
NaI(s) → Na^+(s) + I^-(Aqu)
Oxygen, should be correct
sometimes we use and need mandatory
<span>Gather your materials. Gather the sand, salt and iron filing mixture; a magnet; a paper towel; a cup of warm water; an empty cup; and a piece of filter paper.Use the magnet to remove the iron. ...Use warm water to dissolve the salt. ...<span>Remove the sand from the salt water.</span></span>
The greatest visual evidence you can use when trying to determine if a solution is saturated is to look and see if everything in the test tube is a single color and a single consistency.
