Which statement is correct about the reaction that occurs between copper and aqueous silver nitrate?
2 answers:
Answer: It is a single replacement reaction because copper replaces silver within a compound as copper is higher than silver in the activity series.
Explanation:
Double displacement reaction is one in which exchange of ions take place.
Example:
Single replacement reaction is a chemical reaction in which more reactive element displaces the less reactive element from its salt solution.
Example:
Thus copper being more reactive than silver will replace silver from its aqueous solution to give silver and copper nitrate.

Answer:
The correct option is: A. carbon-12
Explanation:
The CNO cycle, the abbreviation for the carbon-nitrogen-oxygen cycle, is a catalytic cycle by which the stars produce helium from elemental hydrogen, via a series of nuclear fusion reactions.
This cycle involves the fusion of four protons with carbon (), nitrogen isotope (
), and oxygen isotope (
), to give an alpha particle and two electron neutrinos and positrons.
The reaction involves the regeneration of carbon () nucleus in the last step.
