Explanation

The oxidation of glucose to gluconic acid is a reaction that involves the loss of two electrons:

C6H12O6 (glucose) → C6H12O7 (gluconic acid)

Explanation

The combination that will produce a precipitate is NaOH (aq) and Fe(NO3)3 (aq).

Explanation

• In a process at constant volume, the change in internal energy (ΔE) is equal to the heat added to the system (q).
• Therefore, at constant volume, ΔE = q.

Explanation

• The statement that is not true about the precision of data is: "It is the difference between the obtained value and the true value."

Explanation

• The given reaction (CH4 + Cl2 → CH3Cl + HCL) is an example of a free radical substitution reaction.
• Free radical reactions typically exhibit a constant rate over time, regardless of the concentration of the reactants.
• Therefore, the order of this reaction is Zero order.
  

Explanation

• If urea reacts with ammonia according to the Lowry and Bronsted theory, it acts as an acid to form a neutral compound.
• In the reaction between urea (H₂NCONH₂) and ammonia (NH₃), urea donates a proton (H⁺) to ammonia, turning it into the ammonium ion (NH₄⁺) and urea into its conjugate acid (HNCONH₂⁺).
