Odourless, white, cubic crystals.Hygroscopic.Characteristic salty taste.Melting point = 800.8 °C.Boiling point = 1465 °C.Density = 2.165 g/cm³Solubility at 25 °C = 35.9 g/100 g water.Vapour pressure at 865 °C = 1 mm Hg.
The balanced chemical equation of the reaction described above is,
C2H6O + O2 --> H2O + C2H4O2
If we have 3.84 g of oxygen, we divide by its molar mass.
n = (3.54 g Oxygen gas) x (1 mole O2/ 32 g O2)
n = 0.11 moles O2
Using ratio and proportion,
number of moles of ethanol = (0.11 moles O2) x (1 mole C2H6)
= 0.11 moles C2H6
Then, we multiply the calculated value to its molar mass, 46 grams /mol.
mass of ethanol = (0.11 mol) x (46 grams / mol)
= <em>5.06 grams</em>
Answer:
The first one would describe it best
Explanation:
The second option sounds like a single displacement reaction
The third is a decomposition reaction
ANd the first is a combination reaction
