Answer:
The rate is a mathematical relationship obtained by comparing reaction rate with reactant concentrations.
name= calcium
atomic mass= 40.078 atomic mass unit
no of protons= 20
no of electrons=20
The mass number = protons + neutrons. Bromine has a mass number of 80<span> and 35 protons so </span>80<span>-35 = </span>45<span> neutrons. b) How many electrons does the neutral atom of bromine have? The neutral atom of bromine has 35 electrons because the number of electrons equals the number of protons.</span>
the particles from solid to liquid start to move around faster then it was at the first state
