Answer:
c. 2-dimethyl-2-butene or 3-dimethyl-1-butene
4.9 moles of salt are required to be added to 1 kg water to change the boiling temperature
by 5°C.
<h3>What is the moles of Salt required to change the temperature of water by 5°C?</h3>
Based on the given equation, the molality of the solution is calculated as follows:
- Molality = change in temperature/ Kb × I
Change in temperature = 5 °C
Kb = 0.51
i = 2
Molality = 5/0.51 × 2 = 4.9 molal
Also, Molality = moles/kg of water
Moles of salt = molality × kg of water
Moles of salt = 4.9 × 1 = 4.9 moles.
Therefore, 4.9 moles of salt are required to be added to 1 kg water to change the boiling temperature
by 5°C.

Answer:
(True) The answer to that is yes, global warming is a hotly debated topic.
Explanation:
As a matter of political controversy, global warming is often viewed from different political perspectives. Which is why it is still an issue. (In 1988, global warming became a topic of discussion.) A number of climate change-related phenomena are occurring due to climate change, including rising temperatures, droughts and wildfires, changing precipitation patterns, glaciers melting, and rising sea levels.
Hope this helps! :D
The substance that gets dissolved is the solute and the substance that dissolves the solute is the solvent. Example: water is a solvent and salt is a solute
