Question

sollid sodium reacts violently with water producing heat, H gas, and sodium hydroxide. How many molecules of H gas are formed when 35 grams of Na are added to water. Na = 23 g/m; H=1.008 g/m; O= 16 g/m

Answer 1

1. Write general equation
\(Na\left(s\right)\ +\ H_{2}O\left(l\right)→\ NaOH\left(s\right)\ +\ H_{2}\left(g\right)\)
2. Balance the equation
\(2Na\left(s\right)\ +\ 2H_{2}O\left(l\right)→\ 2NaOH\left(s\right)\ +\ H_{2}\left(g\right)\)
3. Use Dimensional Analysis
\(35\ g\ Na\ \cdot\ \frac{1\ mol\ Na}{23g\ Na}\cdot\frac{1\ mol\ H_{2}}{2\ mol\ Na}\cdot\frac{6.023\cdot10^{23\ }Formula\ Units~Na}{1\ mol\ H_{2}}\)

Answer 2

The numbers from the set up lol
