To answer this question, we must first look at the
reactivity series table. From the table, we can see that those which are
located above are the most reactive while those below are less reactive. Which
means that elements cannot replace those elements which are above them.
From the series, platinum is below lead, hence there will
be no reaction.
Answer:
No reaction
Answer:
The order of elements by volume-fraction (which is approximately molecular mole-fraction) in the atmosphere is nitrogen (78.1%), oxygen (20.9%), argon (0.96%), followed by (in uncertain order) carbon and hydrogen because water vapor and carbon dioxide, which represent most of these two elements in the air, are variable.

Answer:
The majority of the weight in an atom is found in the nucleus.
Explanation:
The protons and neutrons that make up the nucleus of the atom may take up a tiny amount of space in comparison to the rest of the atom, but they are far more dense than the electrons that orbit the nucleus.
