Answer : The correct option is, The solvent molecules surround the solute particles.

Explanation :

Dissolving process : It is defined as the process in which solute particles interact with solvent molecules.

When solute particles comes in contact with the solvent particles, firstly the solute particles break down into ions and this result in the Lattice energy of the solute particles.

When solute particles break down, it gets surrounded with the solvent particles and it results in the Hydration enthalpy of the particles.

Hence, the second step of dissolving process is when solvent molecules surround the solute molecules.

A potassium permanganate solution is prepared by dissolving 22.14g of KMnO4 in water and diluting to a total volume of 1.000 L.
gladu [14]

Answer:

The concentration of H₂C₂O₄ is 7,1800x10⁻³ M

Explanation:

The reaction of the titration is:

2 KMnO₄ + H₂C₂O₄ → 2 CO₂ + K₂O + 2 MnO₃ + H₂O

22.14g of KMnO₄ in 1,00L of water have a molarity of:

22,14g KMnO₄/L×\frac{1mol}{158,034g} = 0,14 M of KMnO₄

The moles you required for a complete reaction are:

0,14 mol KMnO₄/L× 0,02050L = 2,872x10⁻³ mol KMnO₄

By the reaction 2 moles of KMnO₄ reacts with 1 mole of H₂C₂O₄, thus, the moles of H₂C₂O₄ that react were:

2,872x10⁻³ mol KMnO₄×\frac{1mol H_{2}C_{2}O_{4}}{2molKMnO_{4}} = 1,436x10⁻³ moles of H₂C₂O₄

As the volume of the sample was 200,0mL≡ 0,2000L, The concentration of H₂C₂O₄ is:

\frac{1,436x10^{-3} mol}{0,2000L} = <em>7,1800x10⁻³ M</em>

I hope it helps!

A fusion reaction takes place between carbon and another element. Neutrons are released, and a different element is formed. The
sdas [7]

Answer:

Dependent on the element that reacted with carbon

Explanation:

Nuclear fusion is the combination of small atomic nuclei into larger ones usually accompanied with the release of a large amount of energy.

From the problem stated, carbon fuses with another atom. The combined atom would have more nuclear particles in terms of protons and neutrons than the combining atoms. This will eventually make it weigh more than carbon and the atom it combines with. The resulting weight will depend on the combining atoms eventually.

The balanced equation for the reaction is

Since given concentrations are at equilibrium state, the expression for the equilibrium constant, k can be written as
