Answer:

Explanation:
You should know that 'liquid' is a state of matter and aqueous means that there is water present.
-It is mentioned that barium chloride is a <u>solution</u>. So you can cut off the C option.
-Barium sulfate is a <u>salt</u> which means it's a solid, so you can cut off the D option.
We now have A and B as the only options remaining.
-Dilute sulfuric acid is definitely not a liquid because water is present. (dilute indicates that there is a greater proportion of water)
The answer should be A.

Ion with a 1+ charge. The atom would normally be neutral, since it has the same number of electrons as it does protons; removing an electron leaves one more proton than electron. Since protons are positive and there's one more of them than electrons in the new ion, it has a 1+ charge.
Answer:
When you heat ice, the individual molecules gain kinetic energy, but until the temperature reaches the melting point, they don't have energy to break the bonds that hold them in a crystal structure. They vibrate more quickly within their confines as you add heat, and the temperature of the ice goes up.
