Answer:
It is 12.00 g of carbon-12.
Explanation:
On yeeeeeeeeeeeee
Answer:
44.11 g/mol
Explanation:
In order to calculate the molar mass of any molecule, we need to add the molar mass of each atom that compounds it:
- Molar Mass of C₃H₈ = (Molar Mass of C) * 3 + (Molar Mass of H)*8
- Molar Mass of C₃H₈ = (12.01) * 3 + (1.01) * 8
- Molar Mass of C₃H₈ = 44.11 g/mol
The molar mass of propane is thus 44.11 g/mol.
combustion reaction are always exothermic in nature...so heat liberated is one of way to identify it
Answer:
338.38 K
Explanation:
Applying,
PV = nRT............... Equation 1
Where P = pressure, V = Volume, R = Temperature, n = number of moles, T = temperature.
Make T the subject of the equation,
T = PV/nR............. Equation 2
From the question,
Given: P = 1.95 atm, V = 12.3 L, n = 0.854 moles
Constant: R = 0.083 L.atm/K.mol
Substitute these values into equation 2
T = (1.95×12.3)/(0.854×0.083)
T = 338.38 K
<span>The correct answer is because there are strong adhesive forces exist between glass and the water molecules. They're not as strong as let's say glue or similar adhesives, but are good and water connected to glass has bigger adhesivity then if it was inside of a wooden cup for example or a bowl.</span>
