The purpose of the scientific method "to use an experiment to test a scientific theory".
<u>Answer:</u> Option C
<u>Explanation:</u>
Researchers use the scientific method when conducting experiments to collect observable, empirical data in a hypothesis-related experiment , the findings that tend to justify or oppose a theory. It's also very important that other researchers can repeat and independently verify the conclusions, logic, and experiments.
Scientific method retains inductive reasoning its position. Scientists use this to formulate theories and hypotheses. In order to adapt the ideas to particular situations, deductive reasoning allows them to do so. Overall scientific methods have become path of analyzing different processes, going in our environment.
I believe it’s b sorry if it’s wrong I took this kind of class last year
Answer:
Ksp = 3.47x10⁻⁹
Explanation:
When Lead (II) iodide (PbI₂) is added to water, the equilbrium produced is:
PbI₂(s) → Pb²⁺(aq) + 2 I⁻(aq)
And solubility product constant, ksp is:
Ksp = [Pb²⁺] [I⁻]²
A solubility of 9.54x10⁻⁴ M means the maximum concentration of Pb²⁺ is 9.54x10⁻⁴ M and 9.54x10⁻⁴ M×2 of I⁻. Replacing in ksp formula:
Ksp = [9.54x10⁻⁴] [2×9.54x10⁻⁴]²
<em>Ksp = 3.47x10⁻⁹</em>
Answer:
"Water and ethyl alcohol will both have dipole-dipole interactions.
Technically they will both have Hydrogen bonding, which is a type of dipole-dipole. This is due to the high electronegativity values of oxygen atoms compared to the carbon and hydrogen atoms the oxygens bond to. This causes regions of both of these molecules that have partial negative charges and other regions wind up with partial positive charges.
Hexane will not have any dipole-dipole interactions because it is a non-polar molecule. The intermolecular forces between hexane molecules will be dispersion forces."
