1) The time depends on what the lab wanted you to do. It will tell you in the procedure when you are supposed to considered a reaction to be complete and you just measure the time for that to happen.
2) Most text books say that increasing the concentration of one or more reactants will increase the rate of the reaction. To prove this with your data you need to show that when you increased the concentration of one of the reactants, the reaction rate did increase. The results of this experiment are not enough to make a general statement since the experiment was not on a large enough scale to diffidently prove anything. (you could have been testing the one exception or had a error in one of your trials)
I hope this helps. Let me know in the comments if anything is unclear.
(The concentration of one or more of the reactants will increase the rate of the reaction. This is explained through the fact that all reactions require collisions that have certain orientations and a minimum energy level. By increasing the concentration of one or more reactants, you increase the number of collisions which increases the rate since requires collisions in order to occur.) <span />
Answer:
Sharing or covalent bonding is taking place.
Explanation:
The valence electron will be shared by both the atoms so that means that the election will move around both of the atoms.
If you mean what is in the solution, then that would be water, sugar, and lemonade powder (That is, if it is not homemade). If this is homemade lemonade, then is is water, sugar, lemon juice, and if you've ever seen homemade lemonade, there's also little bits of lemon floating around too, in which case this would technically be a suspension rather than a solution.
The answer is (3) HCl. The definition of electrolyte is a substance which forms ion in an aqueous solution. Usually it is an ionic compound. While CCl4, C2H6, and H2O are covalent compounds.
Answer:
Ionic bonds are a type of linkage formed from the attraction between oppositely charged ions. The atom that has lost an electron becomes a positively charged ion (called a cation) while the atom that picks up the extra electron becomes a negatively charged ion (called a anion).
Explanation:
I don't exactly know the answer to your question but this is what I know.
Hope it helps:))
