Freddy mixed 10 g of a powdery substance with 200 g of an acid solution. A bubbly solution weighing 205 g was formed. Which best explains why the mass of the new product does not equal the mass of the reactants?

Question 2 options:

A:the other 5 grams weighed less in the acid

B:the other 5 grams created a percipitate (solid)

C:the other 5 grams were released as a gas

D:the other 5 grams changed colors

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
