That happens because in oil and vinegar have a certain density weight.
-A<span>n object will float if it is less dense than the liquid it is placed in.

The sum of all energies involved in breaking and or forming chemical bonds within the reactants side of the reaction is equal to the sum of all energies involved in the formation and rearranging of atoms within the product side of the chemical reaction.
The total energies of reactants = the total energies of products.
Answer:
Stars are made of very hot gas. This gas is mostly hydrogen and helium, which are the two lightest elements. Stars shine by burning hydrogen into helium in their cores, and later in their lives create heavier elements.Stars are huge celestial bodies made mostly of hydrogen and helium that produce light and heat from the churning nuclear forges inside their cores.
Explanation:
1=2 atoms
2=4-n where n is the number of bonds to that carbon
3=10
4=2
