If you were to engineer an everyday solution for conserving water which activity do you think would be the most impactful ?
The answer is motion, this is what I would go with because when you are dealing with gases it puts motion in the term of particles.
The empirical formula of the given compound is 
.
The correct option is B.
<h3>What is an empirical formula?</h3>
The empirical formula of a chemical compound is the simplest whole-number ratio of atoms contained in the substance.
Given,
1.0 g of S
1.5 g of O
To calculate the empirical formula, we will divide the masses of the elements by their atomic weight.
For sulfur
For oxygen
Now, divide the greater value of mole came by the smaller value
Thus, the empirical formula for the given compound is 1 for S and 3 for O

Answer:
Two (2) electron pairs
Explanation:
The sharing of electron pairs by atoms forms a type of bond called COVALENT bond. Atoms that form covalent bonding (share electrons) do so in order to fill their outermost electron shells, hence, gain chemical stability.
However, when two atoms like carbon share TWO PAIRS of electrons with each other, a DOUBLE BOND is formed. An example is the double bond formed in Ethylene (2HC=CH2). A total of four valence electrons (a pair from each carbon) are shared between the two carbon atoms.
True! all matter is made out of atoms & molecules
