Which of the following is a synthesis reaction? 2Na + 2H 2O 2NaOH + H 2 2S + 3O 2 2SO 3 2H 2O 2 2H 2O + O 2 CaCl 2 + F 2 CaF 2 + Cl 2

2S + 3O 2 --->2SO 3 synthesis

Explanation:

2Na + 2H 2O -->2NaOH + H 2 single replacement

2S + 3O 2 --->2SO 3 synthesis

2H 2O 2 --->2H 2O + O 2 decomposition

CaCl 2 + F 2 ---> CaF 2 + Cl 2 single replacement

wanahton purified a portion of water with 900 grams of contaminants. each hour, a third of the contaminants was filtered out.

let g(n) be the amount of contaminants (in grams) that remained by the beginning of the nth hour. g is a sequence, what kind of sequence is it, arithmetic or geometric? then, write an explicit formula for the sequence, g(n)=
