A pure substance that cannot be separated into simpler substances by physical or chemical means. A pure substance composed of two or more elements that are chemically combined.
Answer:
The answer is: 0,13 moles of CO2
Explanation:
We use the formula PV=nRT. The conditions STP are 1 atm of pressure and 273K of temperature:
PV=nRT n=PV/RT
n=1 atm x 2,8 L/ 0,082 l atm/K mol x 273K
n= 0,125078173 mol
The amount of kinetic energy required for the molecules to break free of the intermolecular forced in the liquid is raised because the other ones don’t make sense
Cause its the strongest force inside water
Ionic compounds form between metals and non metals.
