Answer:
146.885 kPa
Explanation:
1 atm= 101.3 kPa =1.013 barr= 760 torr = 760 mmHg= 14.7 psi
So to convert atm to kpa we would multiply 1.45 by 101.3 which gives us 146.885.
1.45atm×
=146.885 kPa
This is true they are defined as protons
The oxygen atom has 4 valence electrons. Valence electrons are the electrons found in the outermost shell of an atom. These are the electrons that participate in chemical reactions during bonding. Since 4 electrons make up 2 pairs, an oxygen atom is capable of making <em>2 covalent bonds</em>.
Among the choices, the polyatomic ion is only the third choice, NH4+ where it is composed of nitrogen one atom of nitrogen and 4 atoms of hydrogen. Choice 2 is a monoatomic atom being composed only of calcium. Then, the first and fourth choices are not ions because they are not charged.
