They become more stable because they achieve a full outer shell of valence electrons with the magic number of 8.
Answer:
0.40 g/cm3
Explanation:
density = mass / volume.
mass = 65.2 grams
volume = 10*1.1*15=165 cm3
so density = 65.2/165=0.40 g/cm3
If an atom has 2 protons, then it must also have 2 electrons for there to be no charge. An extra electron will cause for you to have a negative charge, and if you have more protons than electrons, then you will have a positive charge. :)
D, the rate increases as concentrations increase.
Typically, reaction rates decrease with time because reactant concentrations decrease as reactions are converted to products. Reaction rates generally increase when reactant concentrations are increased.
So really you only need to answer the first one because you have more than enough og everything. 2×(what)=14 then that will be your answer
