Answer: False
Explanation: The plate tectonics move due to convection currents of the mantle; the cooler upper mantle descends while the hotter lower mantles ascend. The heat that drives these convection currents emanated from the core of the earth (not the sun).
Answer:
Balanced chemical equation:
AgCl + 2KCN → K[Ag(CN)₂] (aq) + KCl (aq)
Balanced chemical equation:
2Al + 6NaOH →2 Na₃AlO₃ + 3H₂
Explanation:
Chemical equation:
AgCl + KCN → K[Ag(CN)₂] (aq) + KCl (aq)
Balanced chemical equation:
AgCl + 2KCN → K[Ag(CN)₂] (aq) + KCl (aq)
Net ionic equation can not be written because all are present in aqueous form and no precipitation occur.
Chemical equation:
Al + NaOH → Na₃AlO₃ + H₂
Balanced chemical equation:
2Al + 6NaOH →2 Na₃AlO₃ + 3H₂
This is oxidation reduction reaction.
Hydrogen is reduced in this reaction. while aluminium is oxidized.
