Answer:
2N2 + O2 ⇒ 2N2O
Explanation:
Since I cannot see the product's of the second chemical equation I will only solve the first one.
In order to balance a chemical equation you need to make sure that the atoms on both sides are equal.
In this case we have...
N2 + O2 = N2O
N = 2
O = 2
N = 2
O = 2
Change the coefficient:
N2O = 2N20
2 × 2 = 4
1 × 2 = 2
2N2 + O2 ⇒ 2N2O
Hope this helps.
This is an oxidation reduction reaction
oxidation happens when the species gives out electrons.Oxidation state of the element Cu increases from 0 to +2
Cu ---> Cu²⁺ +2e --1)
Reduction happens when the species gains electrons.
Oxidation state of N reduces from +5 to +2
4H⁺ + NO₃⁻ + 3e ---> NO + 2H₂O --2)
To balance the reactions, number of electrons need to be balanced.
Multiply 1st reaction by 3
Multiply 2nd reaction by 2
3Cu ---> 3Cu²⁺ + 6e
8H⁺ + 2NO₃⁻ + 6e ---> 2NO + 4H₂O
add the 2 equations
3Cu + 8H⁺ + 2NO₃⁻ --> 3Cu²⁺ + 2NO + 4H₂O
add 6NO₃⁻ ions to each side
3Cu + 8HNO₃ --> 3Cu(NO₃)₂ + 2NO + 4H₂O
the balanced redox reaction equation is as follows;
3Cu(s) + 8HNO₃(aq) --> 3Cu(NO₃)₂ (aq)+ 2NO(g) + 4H₂O(l)
Answer:
El ciclo hidrológico comienza con la evaporación del agua desde la superficie. A medida que se eleva, el aire humedecido se enfría y el vapor se transforma en agua: es la condensación. Las gotas se juntan y forman una nube. Luego caen por su propio peso: es la precipitación
