The one question that would give the scientist information about a chemical property of the substance is "Does the substance corrode when left in water?" The correct answer is B.
Answer:
An Atom.
Explanation:
An atom is the smallest particle of a chemical element that can exist. It the fundamental piece of matter. Therefore, splitting carbon into smaller pieces , the smallest piece that would still be called "carbon" would be an Atom of carbon. However, atom is also made of three subatomic particles called electrons, protons and neutrons.
Hey there!
There are 6.022 x 10²³ atoms in one mole.
We have 2.50 moles.
2.50 x 6.022 x 10²³ = 1.51 x 10²⁴
There are 1.51 x 10²⁴ atoms of zinc in 2.50 mols of zinc.
Hope this helps!
Answer:
d) Ni < Co < Fe < Zn < Al
Explanation:
electronegativity of Aluminium 1.6
electronegativity of Zinc 1.7
electronegativity of iron 1. 83
electronegativity of Cobalt 1.88
electronegativity of Nickel 1.91
As the electronegativity of aluminium is lower as compared to other, so it will have high tendency to easily lose electron and that is why Aluminium is more reactive than the other mentioned
Increasing one charged particle by 16 will lead to increasing the electrical force between two charged particles by a factor of 16.
<h3>What is Electrical force?</h3>
This is referred the attractive or repulsive interaction between any two charged bodies present.
F= kq1q2/r²
F1/F2= kq1q2/r² / 16kq1q2/r²
F1/F2 = 1/16
F2 = 16F1
This is therefore how to increase the electrical force between two charged particles by a factor of 16.
