Answer:
1072 torr
Explanation:
To answer this problem we can use <em>Gay-Lussac's law</em>, which states:
Now we convert the given temperatures into K:
- T₁ = 15°C ⇒ 15+273.16 = 288.16 K
- T₂ = 36°C ⇒ 36+273.16 = 309.16 K
We <u>input the data</u>:
- 1000 torr * 309.16 K = P₂ * 288.16 K
And <u>solve for P₂</u>:
The correct answer based on the given question above would be the first option. <span>When a perfume bottle is opened, some liquid changes to gas and the fragrance spreads around the room because gases do not have a definite volume. Hope this answer helps.</span>
Answer:-
The hydrogen atoms have partial positive charges
Explanation:-
In a water molecule there are twp atoms hydrogen and oxygen.
Oxygen has more electronegativity than hydrogen. So the electrons in the bond between Oxygen and hydrogen are more towards oxygen. So hydrogen has a partial positive charge.
The Cl- has negative charge. Positive charge is attracted by negative charge.
Due to this hydrogen atoms in a water molecule are attracted to Cl- ions in sodium chloride (NaCl).
In this case, you are given the water density (62.4lb/ft3) and the water volume (10,000 gallons). But the unit used in the density and gallon is different, so you need to convert it. The calculation would be:
mass= density * volume
mass= 62.4 lb/ft3 * 10,000 gallons * (231 inch3/gallon) * (1 ft3/ 1728 inch3)
mass= 83,416.66 lbs= 81417 lbs
Answer:
Explanation:
The pressure is constant, so, to calculate the volume, we can use Charles' Law:
\dfrac{V_{1}}{T_{1}} = \dfrac{V_{2}}{T_{2}}
Data:
V₁ = ?; T₁ = 450 K
V₂ = 103.4 L; T₂ = 284.9 K
Calculation:
