the first one is ideal
I'm not sure about the last one sorry
Answer:
The correct option is d: carbon and oxygen.
Explanation:
The reaction between carbon and oxygen to form carbon dioxide is:
C + O₂ → CO₂ (1)
On the left side of the above reaction (1), we have the reactants, which are carbon (C) and oxygen (O₂) that react to form carbon dioxide (CO₂), which is the only product of the reaction (on the right side of the reaction).
Hence, the correct option is d: carbon and oxygen.

AGNO3 (s) ----> Ag^+ (aq) + NO3^- (aq) { inorganic reaction }
the dissolution process is endothermic ( absorb energy ) , the crystallization process is exothermic ( release energy )
the temperature will go down and feel cool as the solute dissolves
the rate of crystallization and rate of dissolution will be equal or the same at equilibrium. the rate of dissolution will initially increase , because the process needs to absorb energy to occur , by heating the solution energy is added and the solubility of the solute will decreases more silver nitrate .
