Quantitative observations include numerical data. Ex: 32 degrees, 10 inches, etc.
The density is 3.144 g / cm^3.
<u>Explanation</u>:
If effective number of atom in NaCl type structure, z = 4
a = 705.2 pm ⇒ In centimeter = 705.2 
10^-10
Na = 6.023 10^23
density = (molecular weight) (z) / (Na) (a^3)
where molecular weight of KI is 166 g,
Z represents the atomic number
density = (molecular weight) (z) / (Na) (a^3)
= (166 4) / (6.023 10^23) (705.2 10^-10)
density = 3.144 g / cm^3.
Answer: 
Explanation:
Heat of reaction or enthalpy change is the energy released or absorbed during the course of the reaction.
It is calculated by subtracting the enthalpy of reactants from the enthalpy of products.
= enthalpy change = ?
= enthalpy of products
= enthalpy of reactants
For the given reaction :
Answer:
The relative strength of the four intermolecular forces is: Ionic > Hydrogen bonding > dipole dipole > Van der Waals dispersion forces. ...
Boiling points increase as the number of carbons is increased.
Branching decreases boiling point.
Explanation:
Correct option:
The statement "America is the world’s number one producer of natural gas derived from shale oil" is True.
Shale gas:
- Shale, a form of sedimentary rock, is used to make shale gas, which is natural gas.
- Over the past ten years, shale gas has gained importance as a natural gas source in the United States. Interest has also grown in possible shale gas reserves in Canada, Europe, Asia, and Australia.
- With large production in the US and Canada, North America is the region that produces the most shale gas globally. Only Argentina and China have so far produced shale gas on a commercial basis outside of the US and Canada.
- The environmental dangers associated with shale gas production like, Induced seismicity from hydraulic fracturing has been known to cause earthquakes in three different places across the world and leaks of extraction waste and chemicals into water systems, the release of greenhouse gases during extraction, and the pollution brought on by the poor processing of natural gas have led to its suspension in numerous nations.
