<h3>Answer:</h3>

\displaystyle K_{eq} = \frac{[H_2]^2[O_2]}{[H_2O]^2}

<h3>General Formulas and Concepts:</h3>

<u>Chemistry</u>

<u>Aqueous Solutions</u>

  • States of matter

<u>Kinetics</u>

  • Rate Laws

<u>Equilibrium</u>

  • Equilibrium Reactions RxN ⇄
  • Equilibrium Constants
  • Equilibrium Expression: \displaystyle K = \frac{[Producst]^{coefficients}}{[Reactants]^{coefficients}}
<h3>Explanation:</h3>

*Note: Only gases and liquids affect equilibrium

<u>Step 1: Define</u>

[RxN - Balanced] 2H₂O (g) ⇄ 2H₂ (g) + O₂ (g)

<u>Step 2: Identify</u>

[Reactant] H₂O

  • Coefficient of 2

[Product] H₂

  • Coefficient of 2

[Product] O₂

  • Coefficient of 1

<u>Step 3: Write K Expression</u>

  1. Substitute:                                                                                                       \displaystyle K_{eq} = \frac{[H_2]^2[O_2]}{[H_2O]^2}

The following chemical reactants produce the ester ethyl ethanoate (C4H8O2): C2H6O + CH3COOH What type of reaction occurs to mak
nydimaria [60]

Answer:

Esterification reaction

Explanation:

An esterification reaction is an organic reaction involving an organic acid and an alkanol to give an ester or an ethanoate and water

Like the name suggests, an ester is the product formed in an esterification reaction alongside water. It is like a neutralization reaction but this time it solely contains organic molecules. These molecules react with each other to give rise to another organic molecule which is a member of a different homologous series.

Practically, to form ethyl ethanoate, ethanoic acid react with ethanol in the presence of concentrated sulphuric acid which catalyses the reaction.

An animal cell has a 0.9% saline environment is placed into a solution that is 9% saline. What will happen to the cell
Softa [21]

The concentration of cell is less than that of the solution .

Hence the cell will be called as hypotonic and the solution will be called as hypertonic.

in order to balance the concentration on the two sides of cell (inside and outside in the solution) there will be movement of solvent particles (through semipermeable membrane ) from cell (lower concentration of solute) to solution (higher concentration of solute).

Thus cell will shrink.
