Answer:
V₂ = 119.59 cm³
Explanation:
Given data:
Initial volume = 150 cm³
Initial temperature = 72°C
Final volume = ?
Final temperature = 2°C
Solution:
Initial temperature = 72°C (72 +273.15 K = 345.15 K)
Final temperature = 2°C (2 + 273.15 k = 275.15 K)
Solution:
According to the Charles Law.
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
V₂ = V₁T₂/T₁
V₂ = 150 cm³ × 275.15 K /345.15 K
V₂ = 41272.5 cm³.K / 298 K
V₂ = 119.59 cm³
Answer:
they just add heat, then it turns to water vapor
Explanation:
The first h20 is water the arrow represents adding heat, and the second h20 represent water vapor (water as a gas)
Answer: 
Explanation: Hydrocarbons are the compounds which contain only carbon and hydrogen as their constituent elements. These are considered to be as the non polar species as because of the less electronegativity difference between the two components.
Now as it is a non polar species thus it will dissolve only a non polar solute following the principle of 'Like dissolves Like'. Thus the most non polar species given in the options is pentane. Cyclohexane will definitely dissolve this pentane as both are non polar in nature.
, HI and NaBr are polar specie which cannot be dissolved in non polar species.
It addressed the problem concerning why electrons didn't fall into the positive nucleus. HOPE THIS HELPS BRAINLIEST PLEASE
