BRAINLIEST BRAINLIEST BRIANLIEST BRAINLIEST!! 1. Naturally occurring chlorine that is put in pools is 75.53 percent of 35CI
(mass = 34.969 amu) and 24.47 percent of 37CI (mass = 36.966 amu).
Calculate the average atomic mass. (5 sig figs)

2. Calculate the average atomic mass of bromine. One isotope of bromine
has an atomic mass of 78.92amu and a relative abundance of 50.69%. The
other major isotope of bromine has an atomic mass of 80.92amu and a
relative abundance of 49.31%.(4 sig figs)
Please help me out!:(

answer: they produce more slow than unicellular organisms.

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
