Car tires would look fuller after a car is on a trip. (1) between the tires and the road causes the molecules in the tire to (2). When the molecules (3), they get (4). That causes them to bump into each other and (5), which causes the tires to look (6). Options: faster, slower, spread out, get closer, fuller, flatter, friction, heat up, cool down. ONLY USE EACH ONCE, NOT ALL WILL BE USED.

Idid a lab for chemistry where we put nails in a copper (ii) chloride solution. 1. why did the reaction stop? which reactant was used up? how do you know? 2. describe what was happening to the atoms of iron and copper during the reaction. what is this type of reaction called? 3. what would happen to the ratio of copper to iron if you had placed more nails in the beaker? if you had let the reaction go for less time? 4. what is the accepted ratio of copper atoms to iron atoms in this reaction? account for differences between your experimental value and the accepted value. write the balanced equation for the reaction.
