Answer:
E - Atomic mass is calculated by weighted atomic average using all the isotope data available.
G - Mass number is equal to the sum of protons and electrons in an atom.
Explanation:
Take an element

- Mass no is 25 and atomic no is 12.
The answer is - ide.
That is how you name the anions in a ionic compound, you replace the ending of the name of the element with ide.
Some examples:
Ionic compound anion name of the anion
NaCl Cl- chloride
KF F- fluoride
NaI I- iodide
CaBr2 Br- bromide
We expect the release of PCO2 from the bottle, When the cork is pulled.
<h3>What do you expect to happen?</h3>
When the cork is pulled, we expect the release of PCO2 in the atmosphere to happen because there is high concentration of PCO2 in the bottle but there is no concentration of PCO2 in the atmosphere so due to diffusion, the PCO2 gas moves outside the bottle.
So we can conclude that When the cork is pulled, the release of PCO2 from the bottle will be expected.
