Answer:
2
Explanation:
The atom shown in the image has 2 core electrons.
Electrons are the negatively charged particles within an atom. Therefore the total number of electrons surrounding the nucleus in the given specie is 7.
So;
We have 2 core electrons
And 5 valence electrons
The core electrons are the inner orbital electrons.
The valence electrons are the outermost electrons.
Answer:
C) a low heat of vaporization.
Explanation:
It is C) a low heat of vaporization.
Low heat of vaporization means less amount of energy is required to vaporize a liquid. This further means the liquid has weaker intermolecular force of attraction that is why on provide lesser heat only it vaporizes.
Low vapor pressure, high boiling point and high critical temp. all contribute to strong intermolecular forces in a liquid
Hey there!
No !! there is nothing to react. What else other than tin sulphate and zinc sulphate can you make - but then you have only what you started with .
Hope that helps!
Answer:
1/45 or 0.0222 g/s
Explanation:
rate of reaction = quantity of reactant used/time taken
= (10-8)/90
= 1/45 or 0.0222 g/s
p.s add as brainliest
