What is always conserved in a chemical reaction? (3 points) mass is always conserved in a reaction. energy is always conserved in a reaction. mass and energy are both conserved. nothing is always conserved in a reaction.

Which element in the third period would you expect to have the larger atomic radius, sodium (na) or sulfur (s)? a. sodium, because it has a higher effective nuclear charge attracting electrons in fewer energy levels. b. sodium, because it has fewer protons attracting electrons in the same energy levels. c. sulfur, because it has more protons attracting electrons in more energy levels. d. sulfur, because it has a higher effective nuclear charge attracting electrons in the same energy levels.

Smog is the term used to describe the combination of fog and smoke
