Explanation:
Regulate body temperature in the extremes of space. maybe
Answer:
It starts to become a red giant!
Explanation:
When we can get Pka for K2HPO4 =6.86 so we can determine the Ka :
when Pka = - ㏒ Ka
6.86 = -㏒ Ka
∴Ka = 1.38 x 10^-7
by using ICE table:
H2PO4- → H+ + HPO4
initial 0.4 m 0 0
change -X +X +X
Equ (0.4-X) X X
when Ka = [H+][HPO4] / [H2PO4-]
by substitution:
1.38 X 10^-7 = X^2 / (0.4-X) by solving for X
∴X = 2.3x 10^-4
∴[H+] = X = 2.3 x 10^-4
∴PH = -㏒[H+]
= -㏒ (2.3 x 10^-4)
∴PH = 3.6
Answer: The energy of an electron in the n = 2 level of a hydrogen atom is 3.40 eV.
Explanation:
Given: n = 2
The relation between energy and 
orbit of an atom is as follows.
Substitute the values into above formula as follows.
The negative sign indicates that energy is being released.
Thus, we can conclude that the energy of an electron in the n = 2 level of a hydrogen atom is 3.40 eV.
Answer:
You weight would be doubled because gravitational force is doubled
2. Challenges:
a. Everyone’s body would have to adjust to the new weight and learn to walk again
b. Earth would be closer to the sun, so everything would be hotter on Earth
c. Flying airplanes and driving cars might no longer work at all (talk about how difficult this would make traveling)
3. Benefits:
a. Time would go by much slower so technically everyone would live longer
b. Balloons wouldn’t fly off anymore
4. You have to decide for yourself if you’d like it better or worse
