Answer: Batteries and Food
Explanation:
On the batteries that we use for example for a watch in the kitchen, occurs a chemistry reaction, called redox between Zn and MnO2. The Zn is oxidized (in the anode) and the MnO2 is reduced (in the cathode). In the oxidation, the athom loses electrons and in the reduction the opposites.
Regarding the chemical reactions that occur in the food that we consume, the hydrolisis that occurs in the stomach. The hydrochloric acid that is secreted in the stomach allows the activation of an enzyme, pepsinogen, which hydrolyzes the proteins present in the food consumed. That is, it hydrolyzes the peptide bonds of the proteins, which is between an amino and carboxyl bond of each amino acid that makes them up.

Explanation:
To create a p-type semiconductor, group 14 semiconductors should be d o ped by atoms from group 13.
Answer: The nitronium ion is a strong electrophile
Explanation:
The detailed mechanism of the reaction is shown in the images attached. The flow of electrons has been shown with arrows. HNO3 is first protonated by H2SO4 this protonated specie H2NO3+ now forms H2O and NO2+.
Glucose + oxygen = water + carbon dioxide + energy.
This is the right chemical reaction for respiration
