A. A lake freezes solidB. Gravel, sand, and water are mixedC. A copper bar is rolled into a flat sheet.D. Vinegar bubbles when baking soda is added
a long time, longer than the front. the ones from the factory are better. Once they are replaced once they last about 30,000 miles. You might get 90,000 but I bet they are getting close.
It will be the way some people drive, i.e. if going down a bank you constantly have your foot on the brakes they will ware down more, so the best thing to do it keep tapping the brake instead of riding it
It's D. The freezing of a lake doesn't is only the changing of water into ice; they both still have the same chemical formula When gravel, sand, and water are mixed, they don't react chemically to each other, so they don't change chemical composition. A copper bar being rolled into a flat sheet is only a change in its appearance; it isn't reacting with anything and it doesn't under go any chemical process. When vinegar and baking soda are mixed, they react with each other, forming new compounds in the process; though I don't know the exact reaction that happens.
its the kind of brakes you get and the way you use your brakes and if you havent changed your braakes and it has 92,000 on it i really higly sugest you get them changed and if you hear them sqeek and you press the breaks get them changed becuase thats just meteal on metal rubbing when you brake not good
