Answer: 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.
Answer:
Where the products are H2O and Ba(NO3)2
Explanation:
A base, as, barium hydroxide (Ba(OH)2) reacts with an acid (HNO3), producing water (H2O), and the related salt (Ba(NO3)2) in a reaction called <em>neutralization reaction.</em>
The balanced reaction is:
Ba(OH)2 + 2 HNO3 → 2 H2O + Ba(NO3)2
<em>Where the products are H2O and Ba(NO3)2</em>
Liquids are similar to gases in that they both have <span>no definite shape.</span>
Polar molecules HCl, CHCl3, CH3F is the answer. There is a difference between the electronegativity of the atoms. E.G. the F atom and the C in CH3F
This creates partial charges on them, which are responsible for dipole-dipole forces.
