Can you show me the passage?
The true statements are B, C, and D
-first ( A ) the concentrations of reactants and products are equal is false, As the concentrations of reactants and products may be different from each other.
- But (B) the concentrations of reactants and product remains constant is true, as the equilibrium remains when there is no change in the concentration of the reactants and products.
-(c) reactants are being converted to products (and vise verse) is true also, as there are reactions still happened at a constant rate so it looks like nothing is happening.
Answer:- C. decrease in temperature.
Explanations:- Solubility of a solid increases if the pressure is increased as the high pressure helps the solid to get dissolved in the solvent.
If the surface area of the solute is increased then more and more solute comes into the contact of the solvent and the solubility increases.
If the stirring is increased then it also helps the solute to get dissolved into the solvent.
Solubility of solids is directly proportional to the temperature.
So, if the temperature is decreased then solubility of the solute is also decreased.
Propane: 3 carbon, 8 hydrogen
Carbon dioxide: 1 carbon, 2 oxygen
The correct answer is a.) C. Oxidation occurs when an element loses electrons and increases its oxidation state. In the chemical equation, Carbon in CH4 has an oxidation state of 4- while Carbon in CO2 has an oxidation of 4+.
