Answer:
energy
Explanation:
The photon of light that is emitted as an electron drops back to its original orbit is energy and this energy is released during de-excitation process.
The electron is jumped into higher level and back into lower level by absorbing and releasing the energy.
The process is called excitation and de-excitation.
Excitation:
When the energy is provided to the atom the electrons by absorbing the energy jump to the higher energy levels. This process is called excitation. The amount of energy absorbed by the electron is exactly equal to the energy difference of orbits. For example if electron jumped from K to L it must absorbed the energy which is equal the energy difference of these two level. The excited electron thus move back to lower energy level which is K by releasing the energy because electron can not stay longer in higher energy level and comes to ground state.
De-excitation:
When the excited electron fall back to the lower energy levels the energy is released in the form of radiations. this energy is exactly equal to the energy difference between the orbits. The characteristics bright colors are due to the these emitted radiations. These emitted radiations can be seen if they are fall in the visible region of spectrum
Answer:
3,4-dimethylhexane, CH3CH2CH(OH)CH3, CH3CH2CH(CH3)CH2CH2CH3
Explanation:
A chiral carbon atom is also referred to as a asymmetric carbon atom. This is a carbon atom that is bonded to four different substituents.
So what we need to do is to look at each compound and consider all the carbon atoms in each compound. Drawing out the full structural formula is very helpful here.
After drawing each structure out, we now look out for carbon atoms that have four dissimilar substituents. Those are the chiral carbons. If we do so for all the molecules listed in the answer, we will discover that each of them contains an asymmetric carbon atom.
Answer: the pressure
Explanation: the pressure of the carbonation is in the can and builds up
Answer:
2.174 gm
Explanation:
PV = nRT n = number of moles
R = gas constant = .082057 L-atm/(K-mol)
T must be in units of K
.870 (3.95) = n (.082057)(35+273.15)
solve for n = .1359 moles
Methane mole weight (CH4) = 16 gm / mole
.1359 moles * 16 gm/mole = 2.174 gm
