Answer:
Answer:  What can experiments in a lab tell us about substances on Titan? Experiments in a lab can tell us that the lake did not evaporate in 2007 because the molecular attraction was a lot stronger, then it got weaker overtime.
How does Dr. Hayes' and Dr. Malaska’s research differ? Why are both research projects important? Their research differs because they were both talking about different things, Hayes was talking about how many lakes there were, while Malaska's was doing more hands on stuff like experiments. Both are important because we need to learn how the lakes formed, but we also need to do hands on experiments.

Well, a molecule of this carbohydrate would essentially have no electronegativity difference as it is a Nonpolar compound, and not that of a polar one. All electrons between the atoms would ultimately have a net dipole value of 0, indicating that the molecule is Nonpolar. Thus does not have a partial positive and or a partial negative charge.
        
             
        
        
        
Explanation:
The species with a positive charge over it, which means lack of electrons are called cations. Whereas the species with negative over it, meaning it has an excess of electrons with it are called anions. 
From the list given the cations are
H+, Ba2+, Hg2+, Li+, Ca2+ and Fe2+
Whereas anions from the list are 
O-2, Br-5, F-, S-2. 
A Combination of cation and anions make an ionic compound in which cation is written first and then anion. 
 
        
             
        
        
        
Answer:
Minera and Aragonite
Explanation:
Limestone is a common type of carbonate sedimentary rock. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3). Limestone forms when these minerals precipitate out of water containing dissolved calcium.
