Answer:
luster
i just did it and its luster
Answer: option D) hypothesis
Explanation:
Kim proposal is an hypothesis, because it is an assumption that will ONLY be accepted as true (i.e becomes a theory) when butadiene successfully makes the glue stickier in several conducted experiments.
But, at the moment Kim proposal is an hypothesis.
Elements Y and elements Z would have similar properties due to the fact that they both posses the same number of valence electrons. They both have a single valence electron that determines the corresponding elements bonding properties and the fact that it can either donate 1 valence electron to produce an ion that would be attracted to another atom, that is also an ion. Assuming that these elements are group 1 elements, they do not undergo in covalent bonding.
Answer:
30 feet /second
Explanation:
60 feet/ 2 sec = 30 feet/sec
Answer: A solution forms when the attractive _forces_ between the solute and solvent are _similar/higher_ in strength to the solvent-solvent and solute-solute attractions and are therefore able to replace them.
Explanation: Intermolecular forces between solute and solvent must be able to match or exceed the natural intramolecular forces between the solvent-solvent atoms/molecules and solute-solute atoms/molecules.
This is where the solubility law of 'like dissolves like (polar dissolves polar and likewise)' comes into play. Only polar compounds can form such attractive forces with fellow polar compounds and the same story goes for non-polar compounds.
