Answer:
Carbon Dioxide is an Infrared Radiation Absorber. The (CO2) molecules also emits the absorbed infrared (IR) radiation energy. The photon energy from the infrared radiation causes the CO2 molecule to vibrate. Only some of its vibrational modes absorb infrared radiation
Explanation:
Its linear structure is considered when working with the formula to calculate the number of molecular vibrational modes. It has 3n - 4 vibrational modes, where n is the number of atoms in a compound of CO2
With 3 atoms, CO2 has
3n−5=4 types or patterns of vibration
1. The symmetric stretch
2. The asymmetric stretch
3. The bend
The symmetric stretch vibrational mode is ir-inactive.
The asymmetric stretch is ir-active as it results in changes in dipole moment
The bend is ir-active as well as it results in a change in dipole moment too.
Answer:
2, 4, 1, 3, 5

i believe is this a test
please mark this answer as brainlest i got the answer from someone by the way which is my sis
but forget all of that
please mark brainlest

When discussing discordant and harmonious sound waves, the statement tat is false is : if the original waves combine to form irregular displacement of air, the sound will be discordant. The fact is, irregular displacement of air does not guarantee sound discordance
hope this helps
This deflection of the two hydrogen atoms to one side of the molecule is because of two love pairs of electrons on the other side of the oxygen atoms. In addition, due to the high electronegativity of an oxygen atom (since it has more protons) , it attracts most of the electron cloud of the molecule. The oxygen side of the water molecule is partially negative (negative dipole) while the hydrogen sides are partially positive (positive dipole).
