Mass %abundance # of atoms (pick 1000 sample)
68.9257 60.4% 604
70.9249 39.6% 396
*39.6* ( i got this by subtracting 100 as most percentage is out of 100)
*# of atoms* ( i just moved it one decimal place, then i am going to make the sample out of 1000, to get the decimal place)
Formula= total mass/ total #atoms
x= (68.9257u* 604) + (70. 9249*396)/ 1000
x- 69717. 3832/ 1000
x= 69.717amu or 69.72 amu
if you look on the periodic table the closet element with that mass is gallium ( amu is 69.72)
Answer:
Double-Replacement Reaction
Explanation:
Mg is Oxidized, and O2 is the cause of the oxidation, hence the Oxidizing agent. That means that O2 is Reduced and Mg is the cause naming it the Reducing agent.
OIL - RIG Oxidation is Loss-Reduction is Gain
<span>Nuclear reactions have two main types: fission reactions and fusion reactions. When two light nuclei are joined to create a heavier and more stable nucleus, this process is called the fusion reaction. In the fission reaction, the heavy nucleus split into two nuclei with a smaller mass number. In other words, fission is splitting of atoms although not all atoms undergo fission, only few went through normal circumstances (that is a fact). </span>
