Answer:
CaCO3
Explanation:
The molecule is formed by the calcium cation Ca+2 and the carbonate anion CO3−2.
Using the ideal gas law: PV = nRT; and given the initial conditions:
V1 = 20 cc
T1 = 25 C or 298 K
We are asked to determine the volume at 0 C or 273 K. Assume that the pressure and number of moles are constant. Thus,
V/T = constant, then
V1/T1 = V2/T2
Solve for V2:
20 cc/ 298 K = V2/ 273 K
V2 = 18.32 cc
Explanation:
IR (infrared) spectroscopy theory is based on the concept that the molecules tend to absorb some specific amount of the frequencies of light which are characteristic of corresponding structure of molecules. These energies are reliant on shape of molecular surfaces, associated vibration coupling, and mass corresponding to atoms.
It is used to detect the type of the functional group present in the organic compound.
Because there is a balloon to stop everything from coming out
Answer: The balloon will not survive.
Explanation:
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
where,
= initial pressure of gas = 1 atm
= final pressure of gas = 0.05 atm
= initial volume of gas = 4.0 L
= final volume of gas = ?
= initial temperature of gas =
= final temperature of gas =
Now put all the given values in the above equation, we get:
As the balloon has the capacity to expand to a 50 liter volume before bursting, it can not survive as it occupies volume higher than 50 L
