Solid sodium rapidly reacts with oxygen gas to produce solid sodium oxide. Which reaction equation describes this synthesis reaction?

Na (s) + O2 (g) → Na2O (s)
2Na (s) + O2 (g) → 2Na2O (s)
4Na (s) + O2 (g) → 2Na2O (s)
2Na (s) + O2 (g) → Na2O (s)

Which of the following is true about a carbonated soft drink? . the carbon dioxide is the solvent, and water is the solute.. the water is the solution, and carbon dioxide is the solvent.. the carbon dioxide is the solution, and the water is the solvent.. the water is the solvent, and the carbon dioxide is the solute.. .

Predict the reactants of this chemical reaction. that is, fill in the left side of the chemical equation. be sure the equation you submit is balanced. (you can edit both sides of the equation to balance it, if you need to.) note: you are writing the molecular, and not the net ionic equation. > cacl2(aq) + h20(l)

The solid xy decomposes into gaseous x and y: xy(s) m x(g) + y(g) kp = 4.1 (at 0 °c) if the reaction is carried out in a 22.4 l container, which initial amounts of x and y will result in the formation of solid xy?
