Explanation:
Metals are good reducing agents because they are electron donor which causes co-reactant to be reduced in a reaction.
The position of an element in the activity series determines the strength as a reducing agent or not.
Elements higher in the series are good reducing agents, those lower in the series are poor reducing agents.

Answer:
1.204 x 10²⁴ atoms of oxygen in 1 mole of CO₂
Explanation:
1 mole of CO₂ contains 6.02 x 10²³ molecules of CO₂
1 molecule of CO₂ contains 2 atoms of oxygen
Therefore, Atoms of oxygen in 1 mole of CO2 => 6.02 x 10²³ molecules CO₂ x
2 atoms oxygen / molecule CO₂ = 2 X 6.02 X10²³ atoms of oxygen = 1.204x10²⁴ atoms of oxygen in 1 mole CO₂
Explanation:
Electrons are closer to the nucleus are in filled orbitals and are called core electrons. More energy which in nucleus called nuclear strOng energy to remove electron thars why its also a way harder too..
Answer: Element is a substance that is made entirely from one type of atom. For example, the element hydrogen is made from atoms containing a single proton and a single electron
