Isotopes are variants of a particular chemical element which differ in neutron number, and consequently in nucleon number. All isotopes of a given element have the same number of protons but different numbers of neutrons in each atom.
The term isotope is formed from the Greek roots isos ("equal") and topos ("place"), meaning "the same place".
Answer:
1140 mmHg
Explanation:
1 atmosphere is 760 mmHg, so 1.5 atmospheres is ...
1.5×760 mmHg = 1140 mmHg
Answer:
1.0975 atm.
Explanation:
<em>According to Boyle’s Law:</em> "
At constant temperature , the volume of a given quantity of a gas varies inversely with its pressure".
P α 1/V.
<em>∴ P₁V₁ = P₂V₂.</em>
P₁ = 4.39 atm, V₁ = 0.5 L.
P₂ = ??? atm, V₂ = 2.0 L.
<em>∴ P₂ = P₁V₁/V₂</em> = (4.39 atm)(0.5 L) / (2.0 L) = <em>1.0975 atm.</em>
I believe they are called Energy Levels or Energy Orbitals.
