Best describes the forces in the nucleus of a stable atom is the strong nuclear force balances out the electrostatic force.
The center region of an atom, which is composed of two different types of particles, is known as the atomic nucleus. Protons with positive charges and neutrons with no charges are present. Because of the strong electrostatic attraction between positively charged protons, atomic nuclei should be unstable, however they occasionally remain stable for more than a billion years.
The stability of nuclei suggests that protons and neutrons are attracted to one another by an attractive force. The strong nuclear force, also known as the residual strong force, is responsible for every individual atomic nucleus' stability. Neutrons and protons are held together by this basic force of nature. It is used to explain the atom's and its nucleus' stability, which is otherwise puzzling. It can be used to explain the origin of all atoms and, consequently, the origin of all known simple and complex molecules.

At body temperature, 2404 J is required to evaporate 1 g of water. After vigorous exercise, a person feels chilly because the body is giving up heat to evaporate perspiration. A typical person perspires 25 mL of water after 20 minutes of exercise. How much body heat is used to evaporate this water
Answer: - 1.45 kJ
Explanation:
Using q = m x C x (ΔT)
Given : m = 3.8 g , C = 0.900 J/g°C, = -(450-25)°C = -425°C (Since final temperature is less than the initial, the sign is negative)
q = (3.8 g) x (0.900 J/goC) x ( -425 °C)
= -1453.5 J
= -1.45 kJ
Note that negative sign of q indicates that this much heat is released, when the metal cools down.

If you have a closed container that has a pressure of 2.35atm, and a volume of 1.2L, and contains 76.33g Cl2, what is the resulting temperature in K
The resulting temperature of a closed container that has a pressure of 2.35atm, and a volume of 1.2L, and contains 76.33g Cl2 is 31.8K.
How to calculate temperature?The temperature of a given gas can be calculated by using the ideal gas law equation:
PV = nRT
Where;
P = pressure V = volume n = number of molesR = gas law constantT = temperatureno of moles of Cl2 = 76.33g ÷ 70.91g/mol = 1.08mol
2.35 × 1.2 = 1.08 × 0.0821 × T
2.82 = 0.088T
T = 2.82/0.088
T = 31.8K
Therefore, the resulting temperature of a closed container that has a pressure of 2.35atm, and a volume of 1.2L, and contains 76.33g Cl2 is 31.8K.

How does a noncompetitive inhibitor decrease the rate of an enzyme-catalyzed reaction?.
Answer:
In fact, the inhibitor and substrate don't affect one another's binding to the enzyme at all. However, when the inhibitor is bound, the enzyme cannot catalyze its reaction to produce a product. Thus, noncompetitive inhibition acts by reducing the number of functional enzyme molecules that can carry out a reaction.

what volume of N2 is required to convert 5.0L of hydrogen gas to ammonia? assume that all gases are at the same temperature and pressure and that the reaction is complete
Answer:
Approximately [tex]1.7\; {\rm L}[/tex].
Explanation:
Nitrogen [tex]{\rm N_{2}}\, (g)[/tex] reacts with hydrogen [tex]{\rm H_{2}}\, (g)[/tex] at a [tex]1:3[/tex] ratio to produce ammonia [tex]{\rm NH_3}\, (g)[/tex]:
[tex]{\rm N_{2}}\, (g) + 3\; {\rm H_{2}}\, (g) \to 2\; {\rm NH_{3}}\, (g)[/tex].
The ratio between the coefficient of [tex]{\rm N_{2}}\, (g)[/tex] and the coefficient of [tex]{\rm H_{2}}\, (g)[/tex] is:
[tex]\begin{aligned}\frac{n({\rm N_{2}})}{n({\rm H_{2}})} = \frac{1}{3}\end{aligned}[/tex].
Under the ideal gas assumptions, the same ratio would apply to the volume of [tex]{\rm N_{2}}\, (g)[/tex] and [tex]{\rm H_{2}}\, (g)[/tex] in this reaction:
[tex]\begin{aligned}\frac{V({\rm N_{2}})}{V({\rm H_{2}})} = \frac{n({\rm N_{2}})}{n({\rm H_{2}})} = \frac{1}{3}\end{aligned}[/tex].
[tex]\begin{aligned}V({\rm N_{2}})= \frac{1}{3}\, V({\rm H_{2}})\end{aligned}[/tex].
Given that [tex]V({\rm H_{2}}) = 5.0\; {\rm L}[/tex]:
[tex]\begin{aligned}V({\rm N_{2}}) &= \frac{1}{3}\, V({\rm H_{2}}) \\ &= \frac{1}{3}\times 5.0\; {\rm L} \\ &\approx 1.7\; {\rm L}\end{aligned}[/tex].

NO LINKS PLEASE! Why does dye dropped into a cup of water eventually spread throughout the water?
A. The water has lattice vectors.
B. The water undergoes a phase transition.
C. The water particles and dye particles exhibit Brownian motion.
D. The water exerts pressure on the container.
Answer:
C
Explanation:
okay, you need to look at the structures of the particles of matter in the solid, liquid and gas.
particles in a solid are in fixed positions, where they can only vibrate in those positions ( take a look at ice, or rather, a brick)liquids have very small or rather, no spaces between them, but they can slide or rub against each other, like people in a really tight crowd I guessgas particles have very large spaces between them and they move randomly. these exibit what's called brownian motion.since water particles (and all other liquid particles) have negligible spacings and limited movement, that allows the dye particles to move from a region of high concentration to that of a low concentration. the aim for this is for the mixture/solution to reach an equilibrium, that is the mixture must get to a point where all regions have the same concentration of the dye.you can refer to your coursebooks :)
