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.
Explanation:
Molar mass of O2: 32g/mol
Moles of O2 = 19.5 / 32 = 0.609mol
Answer: When the reaction reaches equilibrium, the cell potential will be 0.00 V
Explanation:
Equilibrium state is the state when reactants and products are present but the concentrations does not change with time.
The equilibrium is dynamic in nature and the reactions are continuous in nature. Rate of forward reaction is equal to the rate of backward reaction.
The standard emf of a cell is related to Gibbs free energy by following relation:
The Gibbs free energy is related to equilibrium constant by following relation:
For equilibrium 
Thus 
Thus When the reaction reaches equilibrium, the cell potential will be 0.00 V
Answer:
5 moles
Explanation:
From the coefficients of the equation, we know that for every 8 moles of nitric acid consumed, 4 moles of water are produced.
So, the answer is 9(4/8), which is 5 moles to 1 sf.
