Independent would be the amount of sugar given and the dependent would be the amount of cavities
Scientists have control groups so they can have evidence to show the difference between that one and the experimental ones.
And the independent variable is the one that changes because with out it changing you wouldn't get different results.
I could be wrong tho sorryyy! but i hope this helps
Some people weren't convinced with the theory. Also many people tried to prove that the atom didn't exist, or at least prove the theory wrong.
According to Dalton's Atomic Theory, the <em>Law of Definite Proportion is applied when a compound is always made up by a fixed fraction of its individual elements.</em> This is manifested by the balancing of the reaction.
The reaction for this problem is:
H₂ + Cl₂ → 2 HCl
1 mol of H₂ is needed for every 1 mole of Cl₂. Assuming these are ideal gases, the moles is equal to the volume. So, if equal volumes of the reactants are available, they will produce twice the given volumes of HCl.
Because it's oil and oil always sits on top of water
Answer: The statement molecule 
cannot be accurately described by a Lewis structure consistent with the octet rule, is true.
Explanation:
As the chemical formula of water is 
and since it contains electronegative oxygen atom which also has 2 lone pair of electrons. Hence, lone pair-bond pair repulsion occurs due to which water has a bent shape structure.
The compound LiF contains metal lithium and non-metal fluorine. In order to obtain stability lithium donates its valence electron to the fluorine atom leading to the formation of an ionic bond. Hence, LiF is an ionic compound and not a covalent compound.
Generally, ionic compounds are polar in nature. For example, KOH is a polar compound and 
is a non-polar compound.
Thus, we can conclude that the statement molecule cannot be accurately described by a Lewis structure consistent with the octet rule, is true.
