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 :)

it's filtration, but this is an assumption so my apologies if i got this

i think it is true since you can test the answer and can use observations to complete it.

i just calculated it all out, and not including weekends, and all the different days off. as of this school year (2018-2019) students are spending 2198 hours in school this year
