C. Weak acids partially ionize
You have already gotten the balanced equation. And the ratio of mol number of reactants and production is the ratio of coefficient. So there is 6.4/8*11=8.8 mol oxygen needed. The mass is 8.8*32=281.6 g.
Answer: Option (d) is the correct answer.
Explanation:
Endothermic process is a process in which energy or heat is absorbed by reactant species.
For example, melting of ice cubes is an endothermic process as it is absorbing heat from the surrounding and gives a cooling effect.
Thus, we can conclude that the process in which a substance gains energy is an endothermic process.
Well, in an atom, there are an equal number of protons and electrons so they cancel each other out.
