Answer: 38L
Explanation:
Initial volume of helium V1 = 35 L
Initial temperature T1 = 20°C
Convert temperature in Celsius to Kelvin
(20°C + 273 = 293K)
New volume V2 = ?
New Temperature T2 = 45°C
(45°C + 273 = 318K)
Since, volume and temperature are involved while pressure is constant, apply the formula for Charles' Law:
(V1/T1) = (V2/T2)
35L/293K = V2/318K
0.119 = V2/318K
To get V2, cross multiply
V2 = 0.119 x 318
V2 = 38L
Thus, the new volume of the balloon is 38 liters
Answer:
C₇H₁₁N
Explanation:
To find the chemical formula, first, let's evaluate the given conditions.
1. <u>Is a primary amine</u>:
This means that the amine is connected to a carbon, like NH₂-R
2. <u>The degree of unsaturation of the five-membered carbon ring is equal to three</u>:
One of the degrees of unsaturation is for the five-membered carbon ring, the other two are for pi-bonds. This means that the five-membered carbon ring has 2 pi-bonds inside.
3. <u>There are seven carbon atoms</u>:
Five of these seven carbons are for the carbon ring and the other two are bonded to the primary amine.
From all of the above, we have that the chemical formula is:
C₅H₅-C₂H₄-NH₂ = C₇H₁₁N
I hope it helps you!
Tamam öğretmenim teşekkür ederiz çok güzel olmuş mu bir
Answer:
Both apply to a certain region
Choice C is correct
Explanation:
Weather refers to the atmospheric conditions of a given place over a short period of time, like a day.
On the other hand, Climate refers to the average climatic conditions of a particular region measured over a long period of time.
Both weather and climate apply to a certain region.
mm = 1500 x 10
