v= 3 m/s
Answer:
A. a technique that separates amino acids on the basis of their polarity
Explanation:
When compounds form, the atoms that bonded get a stable arrangement of electrons.
Compounds form because their atoms get a more stable arrangement than they had in the reactants.
A stable arrangement is a <em>complete octet</em> of eight electrons in the valence shell
.
When the neutrons and electrons are the same. For example, sodium (Na) has an atomic mass of 11, meaning it has 11 protons and 11 electrons etc.
I think the volume should be still 14.3L. In this question, the gas is being held in a tank. The tank has a constant volume. The gas in the tank has the property to fill the space. So when the temperature changes, the pressure changes too. But the volume doesn't change.
