me ayudan porfavor ​

Answer 1

Verified answer

1. Na + O2 → Na2O3

1= Na =2

2= O = 3

4Na + 3O2 → 2Na2O3 RESPUESTA

4= Na =4

6= O = 6

2. N2 + H2 → NH3

2= N = 1

2= H = 3

2N2 + 6H2 → 4NH3 RESPUESTA

4= N = 4

12= H = 12

3. H3PO4 + Mg (OH)2 → Mg3 (PO4)2 + H2O

5= H = 2

1= P = 2

6= O = 9

1= Mg = 3

2H3PO4 + 3Mg (OH)2 → Mg3 (PO4)2 + 6H2O RESPUESTA

12= H = 12

2= P = 2

14= O = 14

3= Mg = 3

4. C11H22 + O2 → CO2 + H2O

11 = C = 1

22 = H = 2

2 = O = 3

2C11H22 + 33O2 → 22CO2 + 22H2O RESPUESTA

22 = C = 22

44 = H = 44

66 = O = 66
