Question

Na+N2= Ca+P= Al+H2O= Zn+H2O=

Answer 1

1) 6Na+N₂=2Na₃N
2) 3Ca+2P=Ca₃P₂
3) 2Al+6H₂O=2Al(OH)₃+3H₂↑
4) Zn+H₂O=ZnO+H₂↑

Answer 2

The equations you've provided appear to represent chemical reactions. Here are the balanced chemical equations for each reaction:

1. Na + N2 → 2NaN (Sodium reacts with nitrogen gas to form sodium nitride)
2. Ca + P → Ca3P2 (Calcium reacts with phosphorus to form calcium phosphide)
3. 2Al + 6H2O → 2Al(OH)3 + 3H2 (Aluminum reacts with water to form aluminum hydroxide and hydrogen gas)
4. Zn + 2H2O → Zn(OH)2 + H2 (Zinc reacts with water to form zinc hydroxide and hydrogen gas)

Please note that the equations provided are balanced based on stoichiometry, ensuring that the number of atoms of each element is equal on both sides of the reaction.
