Hello, I need some help, please. balance these equations by writing the proper coefficients in the blanks provided. 1. Mg + O2 --> MgO
2. P + O2 --> P2O5
3. S + O2 ---> SO2
4. Na + Cl --> NaCl
5. CaCO3 --> CaO + CO2

thank you :)

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?

0.042

0.42

2.4

24

the answer is symmetrical : )
