2NH₂ + O₂ → N₂ + 2H₂O

<u>Explanation:</u>

Balancing the equation means, the number of atoms on both sides of the equation must be the same.

In the case of the given equation, we have to find out whether it is balanced or not.

2NH₂ + O₂ →  N₂ + 2H₂O

Atoms       Number of atoms before balancing     after balancing

                 LHS                 RHS                                    LHS         RHS

N               1                        2                                            2              2

H               2                       2                                            4              4                        

O               2                       1                                            2                2

To balance the N atoms, we have to put 2 in front of NH₂, and then to balance the H, O atoms, we have to put 2 in front of H₂O, so that each atom in left hand as well as right hand side of the equation was balanced.

How does an underwater earthquake cause a tsunami? I need this for an assignment, if you could send me some links or a thoroughl
mars1129 [50]
An earthquake happens when tectonic plates move against each other. A oceanic and a continental tectonic plates might move against each other. When that happens water is pushed upwards and it creates ripples that then move towards land. It's like throwing a rock in water but a lot bigger. I can't post external links on Brainly but you can find more information about tsunami's on Google
