QuestionAnswer
IN CARBON DIOXIDE OXYGEN IS ... ELECTRONEGATIVE THAN CARBON, SO IS NEGATIVE AND CARBON IS POSITIVE IN C02. HOWEVER THE MOLECULE IS LINER SO THE DIPOLES CANCEL OUT AND IS NON POLAR.
3 WAYS THE MOLECULE CAN VIBRATE ARE. .. ASYMMETRICAL STRETCHING, SYMMETRICAL STRETCHING AND BENDING.
DOES SYMMETRICAL STRETCHING CAUSE CHANGE IN DIPOLE... DOESN'T CAUSE A CHANGE IN DIPOLE MOMENT AND DOESN'T ABSORB INFRARED RADIATION.
ASYM STRETCHING , BENIDNG CAUSE.... A CHANGE IN DIPOLE MOMENT FROM ZERO AND ARE INFRARED ACTIVE. CO2 ABSORBS INFRARED RADIATION IS AN GREENHOUSE GAS.
WHY IS C02 A GREENHOUSE GAS .... ABSORBS INFRARED RADIATION IS AN GREENHOUSE GAS.
IN METHANE THE C-H BOND.... IS POLAR. ELCTRONEGATIVITY OF CARBON IS 2.5 =.
ARE TETRAHEDRALNON POLAR... YES , COZ DIPOLE CANCELL
ANY ASYMMETRICAL BENDING OR STRETCHING CAUSES THE MOLECULE.... TO HAVE A DIPOLE MOMENT SO METAL ABSORBS INFRARED RADIATION.
ALL POLAR MOLECULES ARE... INFRARED ACTIVE.
WATER THE OXYGEN ATOM... WATER IS NEG AND HAS 2 LONE PAIRS OR ELECTRONS.SO MOLECULE IS POLAR. IT ABSORBS INFRARED IN BENDING STRETCHING MODES.
WHEN DOES WATER ABSORB INFARED ... IN BENDING ANS STRCHING ,MODES IT IS A MAJOR GREENHOUSE GAS.
METHANE WATER AND METHANE ARE ALL ... IGREENHOUSE GASES.
ELCTORNEGATIVITY OF NITROGEN IS 3.0 & OXYGEN IS 3.5. SO... OXYGEN POLAR.
WHAT IS NITRIC OXIDE DIPOLE MOMENT.. NO, IS DIATOMIC POLAR MOLECULE AND HAS A DIPOLES MOMENT OF 0.16
D.NITROGEN DIOXIDE IS SHAPED... V SHAPED WITH DIPOLE MOMENT OF 0.40D. SO BOTH ABSORBED INFRARED AND ARE GREENHOUSE GASSES.
IF YOUR POLAR AND HAVE DIPOLE MOMENT ... YOU ABSORB INFRARED AND ARE GREENHOUSE GASES.
SOLAR RADIATION ON EARTH HAS WAVELENGTH... OF 400NM-700NM.
THE ATMOSPHERE ABSORBS ... UV BUT SOME RADIATION IS THE VISIBLE REGION PASSES THROUGH THE GASEOUS MOLECULES IN THE AIR.
WHAT HAPS TO RADIATION ABSORBED BY ATM ... RADIATION IS REFLECTED BACK TO SPACE,BY WHITE SNOW AND POLAR ICE ON MOUNTAINS.
WHAT HAPS TO REMAINDER... THE REMINDER IS ABSORBED BY THE CLOUDS AND EARTH.
WHAT IS THE RADIATION REFLECED BACK TO SPACE BY... WHITE SNOW , POLAR ICE ON MOUNTAINS.
THE RADIATION EMITTED BACK INTO SPACE BY EARTH WAVELENGTH... A LONGER WAVELENGTH, (IN THE INFRARED REGIONS).
