boiling point (intensive): the temperature at which a substance boils.
melting point (intensive): the temperature at which a substance melts.
The balanced chemical reaction for this would be written as:
2Mg + O2 = 2MgO
We use this reaction and the amount of the reactant given to calculate for the amount of magnesium oxide that is produced. We do as follows:
1.5 g Mg (1 mol / 24.31 g) ( 2 mol MgO / 2 mol Mg ) (40.30 g /1 mol ) = 2.49 g MgO produced
Answer:
V₂ = 1223.2 mL
Explanation:
Given data:
Pressure of gas = 820.4 mmHg
Initial volume of gas = 900.0 mL
Initial temperature = 25.0°C (25+273=298K)
Final temperature = 132.0°C (132.0 +273 = 405 K)
Final volume = ?
Solution:
Solution:
The given problem will be solve through the Charles Law.
According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.
Mathematical expression:
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 = 900.0 mL × 405 K / 298 k
V₂ = 364500 mL.K / 298 K
V₂ = 1223.2 mL
