The statement “Only the “Conclusion” section discusses whether the original hypothesis was supported, and both sections suggest further research”, best describes the difference between analysis and conclusion.
Answer: Option 4
<u>Explanation:
</u>
In research, we do experiments and derive the results. Then, those results were analyzed by us. In this analysis part, we compare our results with the related results published elsewhere. Also, we correlate the similarities and point out the differences between our analysis and other reported results.
In conclusion part, we have to check hypothesis or it supported. And, we summarise our analysis and figure out the further research need to be done on that to improvise our research. So, the final statement is the correct option which best describes the difference between analysis and conclusion.
Answer:
V₂ = 0.98 L
Explanation:
Given data:
Initial volume = 750 mL =0.75 L
Initial pressure = 745 mmHg (745/760 =0.98 atm)
Initial temperature = 25 °C (25 +273 = 298 K)
Final temperature = -35°C (-35+273 = 238 K)
Final volume = ?
Final pressure = 0.60 atm
Formula:
P₁V₁/T₁ = P₂V₂/T₂
P₁ = Initial pressure
V₁ = Initial volume
T₁ = Initial temperature
P₂ = Final pressure
V₂ = Final volume
T₂ = Final temperature
Solution:
P₁V₁/T₁ = P₂V₂/T₂
V₂ = P₁V₁T₂/T₁ P₂
V₂ = 0.98 atm × 0.75 L × 238 K / 298 K × 0.60 atm
V₂ = 174.93 atm .L. K / 178.8 K.atm
V₂ = 0.98 L

now plz give me 5 stars and press on the heart plz
Here are the given:
<span>ΔHf° = –423 kJ/mol
</span> ΔHsub = 119 kJ/mol
IE = 469 kJ/mol
ΔHEA = –301 kJ/mol
BE = 161 kJ/mol
The lattice energy of the compound is solved using the formula:
U = <span>ΔHf° - </span>ΔHsub - BE - IE - ΔHEA
U = -423 - 119 - 161 - 469 - (-301)
U = -871 kJ/mol
Therefore, the lattice energy is 871 kJ/mol (released).
