Answer: A
The protons in the nucleus repel each other
Explanation:
the number of protons inside a nucleus increases the electrostatic repulsion between protons increase reducing the binding energy. Thus the electrostatic force determines the stability of a nuclear configuration
Explanation:
(a)
The given data is:-
Energy = 2391 Calories
The conversion of calories to J is shown below as:-
1 calorie = 4.184 J
So,
Energy = 4.184 * 2391 J = 10003.944 J
Answer in four significant digits: - 
(b)
The conversion of calories to kJ is shown below as:-
1 calorie = 0.004184 kJ
So,
Energy = 0.004184 * 2391 kJ = 10.003944 kJ
Answer in four significant digits: - 
(c)
The conversion of calories to kWh is shown below as:-
1 calorie = 
kWh
So,
Energy = 
kWh = 0.002778873 kWh
Answer in four significant digits: - 
Answer:
The planets Mercury, Venus, Earth, and Mars, are called terrestrial because they have a compact, rocky surface like Earth's terra firma. The terrestrial planets are the four innermost planets in the solar system.

Answer:
0.20 moles
Explanation:
The pressure is proportional to the quantity of gas at a given temperature and volume. So, the quantity needs to be increased by a factor of ...
(35 psi)/(29.2 psi) = 175/146 ≈ 1.19863
The fractional increase required is ...
1.19863 -1 = 0.19863
__
The quantity of air currently in the tire is ...
1 mol·519.67°R/(atm·23.6442 L) × (29.2/14.7 atm) × (11.6 L) / (45+459.67)°R
= 1.0035 mol
so we need to add ...
(fraction to add) × (current quantity) = amount to add
0.19863 × 1.0035 mol = 0.1993 mol = amount to add
About 0.20 moles of air must be added to the tire to bring the pressure up.
Hey there!
Molar mass of CaCl₂:
Add the molar masses of each element multiplied by the amount of that element we have.
Ca: 1 x 40.078
Cl: 2 x 35.453
---------------------
110.98 grams
The molar mass of calcium chloride is 110.98 grams.
Hope this helps!
