Answer:
chemical reaction are the processes in which new substances with new properties of from are called as chemical reaction ex double displacement reaction
Explanation:
For the first one the pattern is multiply the previous number by five as you see 1 x 5 = 5 and so on. To keep adding to it you would do
125 x 5 = 625 625 x 5 = 3125 3125 x 5 = 15625
Now for the second one the pattern is divide the previous number by three as you can see 2187 / 3 = 729 and so on. To keep going you would
81 / 3 = 27 27 / 3 = 9 9 / 3 = 3
I hope this helps you and if you have anymore questions i'll be glad to answer them.
Characteristic properties are used because the sample size and the shape of the substance does not matter.
They all have the same number of electrons in the electron cloud.
