First, calculate the number of moles of sodium present with the given mass,
31.5 g of sodium x (1 mol sodium/ 23 g sodium) = 1.37 mol sodium
It is given in the equation that for every 2mols of sodium, one mol of H2 is produced.
mols of H2 = (1.37 mols sodium)(1 mol H2/ 2 mols sodium)
mols of H2 = 0.685 mols H2
Then, at STP, 1 mol of gas = 22.4 L.
volume of H2 = (0.685 mols H2)(22.4 L / 1 mol)
volume of H2 = 15.34 L
Answer: 15.34 L
Answer:
Sodium Hydroxide turns blue litmus red .
Answer:
The balanced equation for methanol when is burned in the air, is
CH3OH + O2 -----> 3/2 CO2 +2 H2O and as you see coefficient of oxygen is 3/2
Explanation:
When you always burn something you are doing combustion. The reactives are your compound + O2, and as products you have CO2 and H2O
Answer:
The period 2 element would be more reactive because the attractive force of protons is stronger when electrons are attracted to a closer electron shell.
Explanation:
Nonmetals want to add more electrons to their valence electron shell. Elements in period 2 have their valence shell closer their nucleus, then they are more reactive than period 4 elements.
