What is the quantity of hydrogen gas liberated when 46 g of sodium reacts with excess ethanol?

2.4 × 10-2 kg.

How many grams of H2 are released when 46g of Na?

Now we have to find the quantity of hydrogen gas liberated during this reaction which is generally calculated by calculating the moles of sodium ions. Thus the quantity of \[{{H}_{2}}\]gas is 2 g or \[2.0\times {{10}^{-3}}\]kg. Hence option B is the correct answer.

What mass of hydrogen is produced?

It means 14.4 grams of hydrogen is produced at the end because H2 has a mass of 2 grams per mole.

Which gas is liberated when sodium is added to water?

In soluble form sodium always occurs as Na+ ions. In what way and in what form does sodium react with water? A colourless solution is formed, consisting of strongly alkalic sodium hydroxide (caustic soda) and hydrogen gas. This is an exothermic reaction.

Is ethanol a natural product?

Ethanol is a natural byproduct of plant fermentation and also can be produced through the hydration of ethylene.

How is hydrogen gas liberated?

Hydrogen gas is liberated in the reaction of sodium hydroxide with CO2.

Why is hydrogen liberated at the cathode?

Answer: Because generally hydrogen has 1 electrone and it looses it so it get positive charge on it where positive and negative attract each other and cathode has negative charge.

Is there ethanol in wine?

Whether you drink beer, wine or spirits, they all contain the same type of alcohol called ethanol. This is created when either fruits or grains are fermented to produce alcohol drinks.

How is bioethanol fuel made?

Bioethanol fuel is mainly produced by the sugar fermentation process, although it can also be manufactured by the chemical process of reacting ethylene with steam. The main sources of sugar required to produce ethanol come from fuel or energy crops.

What is the molar mass of hydrogen H2?

2.016 grams per mole
The molar mass of hydrogen gas is 2.016 grams per mole.
