The answer would be the closest to the inside, so the last option. Hope I helped :)

Answer: Option (D) is the correct answer.

Explanation:

Strong nuclear force is defined as the force that is able to hold both the protons and neutrons together in an atomic nucleus.

Since protons have a positive charge and neutrons have no charge. And like charges repel each other. Therefore, protons repel each other due to electrostatic force of repulsion. This force of repulsion is overcome by nuclear binding energy that is also known as strong nuclear force.

This binding energy helps the protons to be bind with each other.

Thus, we can conclude that strong nuclear force will happen inside C.

How many grams of magnesium metal will react completely with 4.8 liters of 5.0 M HCl? Show all of the work needed to solve this

vovikov84 [41]

V=4.8 L
c=5.0 mol/L
M(Mg)=24.3 g/mol

1) n(HCl)=cv

2) m(Mg)=M(Mg)n(HCl)/2

3) m(Mg)=M(Mg)cv/2
m(Mg)=24.3*5*4.8/2=291.6 g

Calculate the pH of a solution that is 0.113 M HCI.

Alex Ar [27]

Simplified concentration

$\\ \rm\Rrightarrow 1.13\times 10^{-2}M$

Now

$\\ \rm\Rrightarrow pH=-log[H^+]$

$\\ \rm\Rrightarrow pH=-log(1.13\times 10^{-2})$

$\\ \rm\Rrightarrow pH=-log1.13-log10^{-2}$

$\\ \rm\Rrightarrow pH=-0.05+2$

$\\ \rm\Rrightarrow pH=1.95$

A piece of silver (Ag) metal weighing 194.3 g is placed in a graduated cylinder containing 242.0 mL of water. The volume of wate

mariarad [96]

Answer: The density of silver metal will be $10.50g/ml[\tex]Explanation:Density is defined as the mass contained per unit volume.[tex]Density=\frac{mass}{Volume}$

Given : Mass of silver = 194.3 grams

Volume of silver= volume of water displaced= $260.5-242.0=18.5mltex]Putting in the values we get:[tex]Density=\frac{194.3g}{18.5ml}=10.50g/ml/tex]Thus density of silver metal will be [tex]10.50g/ml$

Which best describes what happens when 50 mL of 0.0010M CaCl2 is added to 50 mL of 0.010M Na2SO4? (The Ksp of CaSO4 = 2.4 × 10–5

Julli [10]

When the solutions are diluted in half:
So [ Ca+2] = 0.001/2 = 0.0005 M
[SO4-2]= 0.01/2 =0.005

when Q = [Ca2+][SO4-2]
so by substitution:

Q = 0.0005*0.005 = 2.5x10^-6
by comparing with Ksp value
So when Q < Ksp
∴ the answer is no precipitation will occur, as the solution is unsaturated.
