Answer 2

Balancing Chemical Equations

Rb + Se:

The balanced chemical equation for the reaction between Rb (Rubidium) and Se (Selenium) is:

2 Rb + Se -> Rb2Se NaH + H2O:

The balanced chemical equation for the reaction between NaH (Sodium Hydride) and H2O (Water) is:

NaH + H2O -> NaOH + H2 Cs + N2:

The balanced chemical equation for the reaction between Cs (Cesium) and N2 (Nitrogen) is:

2 Cs + N2 -> 2 Cs3N Na2O2 + CO2:

The balanced chemical equation for the reaction between Na2O2 (Sodium Peroxide) and CO2 (Carbon Dioxide) is:

2 Na2O2 + 2 CO2 -> 2 Na2CO3 + O2 I hope this helps! If you have any more questions or need further assistance, feel free to ask.
