D. Common characteristics
Answer: The energy of the products exceeds the activation energy threshold.
Explanation:
In the reverse reaction, the reactants of the forward reaction are now the products of the reverse reaction and vice versa.
This means that normally since you would need the energy of the reactants of the forward reaction to exceed the activation energy threshold, in the reverse reaction, the energy of the products would need to exceed the activation energy threshold.
P1V1=P2V2
100mL•500 mmHg=V2•1000mmHg
50000=V2•1000mmHg
50000/1000mmHg=V2
V2=50mL
Answer:
The energy for the transition of an electron from the n = 5 level to the n = 6 level of a hydrogen atom is .
Absorption is taking place.
Explanation:
where,
= energy of orbit
n = number of orbit
Z = atomic number
Energy of n = 5 in an hydrogen atom:
Energy of n = 2 in an hydrogen atom:
Energy for the transition of an electron from the n = 5 level to the n = 6 level of a hydrogen atom = E
Positive value of energy means that absorption is taking place that electron excite from lower energy level to higher energy level by absorbing the energy.
E =
The energy for the transition of an electron from the n = 5 level to the n = 6 level of a hydrogen atom is .
Answer:
Waters' boiling point decreases with increases in elevation because of the atmospheric pressure.
For example, the higher in elevation you are. The lower the atmospheric pressure is. In other words heated water reached boiling point quicker.
