Answer:

True

Explanation:

The strong nuclear force is at times more rapidly than the electromagnetic force (EM). In essence, this can be given by the relationship:

\frac{1}{r^{-7} } instead of \frac{1}{r^{-2} }

Therefore, the strong proton – proton repulsion between two atoms with smaller radii is able to overcome to overcome non-charge forces, in this case, the gravitational and electromagnetic forces.

Protons and neutron exist of quarks. It requires a strong magnetic force to overcome the strong residual repulsion between two protons.

a balloon filled with 750.0 ml of helium at a temperature of 25 degrees celsius and an atmosphere pressure of 745 mm Hg. What vo
Softa [21]

Answer:

V₂ = 0.98 L

Explanation:

Given data:

Initial volume = 750 mL  =0.75 L

Initial pressure = 745 mmHg (745/760 =0.98 atm)

Initial temperature = 25 °C (25 +273 = 298 K)

Final temperature = -35°C (-35+273 = 238 K)

Final volume = ?

Final pressure = 0.60 atm

Formula:

P₁V₁/T₁ = P₂V₂/T₂  

P₁ = Initial pressure

V₁ = Initial volume

T₁ = Initial temperature

P₂ = Final pressure

V₂ = Final volume

T₂ = Final temperature

Solution:

P₁V₁/T₁ = P₂V₂/T₂  

V₂ = P₁V₁T₂/T₁ P₂

V₂ = 0.98 atm × 0.75 L × 238 K / 298 K × 0.60 atm

V₂ = 174.93 atm .L. K / 178.8  K.atm

V₂ = 0.98 L

Romashka-Z-Leto [24]
A solution with a pH of 6 is acidic.  a solution is considered acidic when the pH<7 while a solution is considered basic when the pH>7 (a neutral solution has a pH=7).

I hope this helps.  Let me know if anything is unclear.
