The farther away the object is from the ship. For sound to bounce back, it has to travel there and back. Thus, the longer it's out there, the farther it is.
1. Mg + CuSO4 —> MgSO4 + Cu
=> Single displacement reaction
2. 2HCI + Mg(OH)2 —> MgCI2 + H2O
=> Acid - base reaction
3.AgNO3 + NaCI —> AgCI + NaNO3
=> Double displacement reaction
Hey there!
Assuming you want the equation balanced:
NH₄NO₃ → N₂O + H₂O
Balance N.
2 on the left, 2 on the right. Already balanced.
Balance H.
4 on the left, 2 on the right. Add a coefficient of 2 in front of H₂O.
NH₄NO₃ → N₂O + 2H₂O
Balance O.
3 on the left, 3 on the right. Already balanced.
Your final balanced equation:
NH₄NO₃ → N₂O + 2H₂O
Hope this helps!
When a solid melts, heat is required to break apart the bonds of the tightly packed molecules. As energy is added to the solid, the motion of the molecules speed and are able to move around more freely.
