Main Answer:

Based on the given hypothetical reaction, the rate of disappearance of "B" can be determined by the following relation:

Δ[B]/Δt = -(3/2) Δ[C]/Δt

Explanation:

What is hypothetical reaction ?

Hypothetical reaction is one of the representation of the equation in which reactants and products are involved. The reactants will always lies on the left hand side of the equation and the products will always lies on the right hand side of the equation. The rate of disappearance of the reactants will result in the rate of formation of the products. At a certain stage of reaction, all the reactants and products are there, the condition is equilibrium state. If the equilibrium state shifts right, then it will lead to the formation of products. In the above equation, A and B are the reactants and C is the product.

Calculate the weight of 3.491 into 10 to the power 19 molecules of cl2​
Rom4ik [11]

Answer:

The mass of 3.491 × 10¹⁹ molecules of Cl₂  of Cl₂ is 4.11 × 10⁻³ grams

Explanation:

The number of particles in one mole of a substance id=s given by the Avogadro's number which is approximately 6.023 × 10²³ particles

Therefore, we have;

One mole of Cl₂ gas, which is a compound, contains 6.023 × 10²³ individual molecules of Cl₂

3.491 × 10¹⁹ molecules of Cl₂ is equivalent to (3.491 × 10¹⁹)/(6.023 × 10²³) = 5.796 × 10⁻⁵ moles of Cl₂

The mass of one mole of Cl₂ = 70.906 g/mol

The mass of 5.796 × 10⁻⁵ moles of Cl₂ = 70.906 × 5.796 × 10^(-5) = 4.11 × 10⁻³ grams

Therefore;

The mass of 3.491 × 10¹⁹ molecules of Cl₂  of Cl₂ = 4.11 × 10⁻³ grams.

Why does LiCl does not exhibit frenkel defect?
tino4ka555 [31]
Frenkel defect is a defect in crystalline solids in which an atom is displaced from its lattice position to an interstitial space. This creates a vacant space at the original site and an  interstitial defect at the new site within the same element. This defect does not affect the chemical properties of the compound. This defect usually occur in ionic solids with large size difference between the anion and cation.
LiCl does not exhibit Frenkel defect because the size difference between the anion and the cation of the compound is very small.

What is the process that changes the composition of rocks by dissolving them called?
Thepotemich [5.8K]

Answer:

Chemical weathering

Explanation:

This is a chemical weathering since chemical change is involved. water flows through the rock, it dissolve the rock particles, reacting with the minerals salts in the rock there by producing new substances, ultimately leading to wearing off of the rock particles
