Answer: B
. particle size
Explanation:
Let's begin by explaining that a molecular sieve is a device, whose composition allows the absorbtion of molecules that are small enough to pass through its pores, since it is made up of small pores of a precise and uniform size.
Thus, very small molecules manage to pass through the pores of the sieve, while large ones do not.
So, based on this premise, a molecular sieve separates the substances by their size.
Hence, the correct option is B.
Answer: Image result for What is the Lewis dot structure for N2socratic.org
Transcript: For the N2 Lewis structure, we have five valence electrons for Nitrogen--it's in group 5 or 15 on the periodic table. We have two Nitrogens. Multiply those together, we have a total of 10 valence electrons for the N2 Lewis structure.
Answer:
The ratio of reactants and products in a chemical reaction is called chemical stoichiometry . Stoichiometry depends on the fact that matter is conserved in chemical processes, and calculations giving mass relationships are based on the concept of the mole . One mole of any element or compound contains the same number of atoms or molecules, respectively, as one mole of any other element or compound.
