Answer:
Wave particle duality is most apparent in analyzing the motion of. an electron. A photon of which electromagnetic radiation has the most energy.
We have to fill the gap
The correct answer is: Metals with the largest atoms and the smallest number of valence electrons and non-metals with the smallest atoms and the greatest number of valence electrons are the most reactive.
Reactivity of any species depends on ease of release or gain of electron. The species which can release electron easily from valence shell, the species is more reactive whereas the species which can accept electron to its valence shell easily is also more reactive.
Answer:
Mass = 684.2 g
Explanation:
Given data:
Moles of Aluminium = 25.36 mol
Mass of Al = ?
Solution:
Formula:
Number of moles = mass/ molar mass
Mass = number of moles × molar mass
Molar mass of Aluminium = 27 g/mol
Now we will put the values:
Mass = 25.36 mol × 26.98 g/mol
Mass = 684.2 g
