How many moles of hydrogen gas are produced when 0.066 mole of sodium is completely reacted?
The balanced chemical equation for the reaction between sodium and water is: 2Na + 2H2O -> 2NaOH + H2 This means that for every mole of sodium (Na) reacted, one mole of hydrogen gas (H2) is produced. Therefore, when 0.066 mole of sodium is reacted, 0.066 mole of hydrogen gas will be produced.
Why sodium metal not ordinarily reacted in the laboratory even with a dilute acid?
The reaction of sodium with dilute acid and even pure water is violent. The reaction produces hydrogen gas, which ignites and in turn ignites the sodium. In some cases the sodium can explode, sending droplets of burning, molten sodium into the air.
Is sodium bicarbonate a pure substance or mixture?
It is a pure substance as well as a compound
Is sodium hydrogen carbonate an element?
No, sodium hydrogen carbonate is a compound. If a substance has more than one element mentioned in its name (this one has three) it is not an element.
Why is sodium metal not ordinarily reacted in the laboratory even with a dilute acid?
The reaction is violent, even explosive. The sodium reacts with an acid to produce a sodium salt and hydrogen gas. The reaction produces enough heat to melt the sodium and ignite the hydrogen. If the reaction does produces an explosion it can send flaming, molten pieces of sodium through the air. For these reason the reaction is dangerous.
Why is sodium metal not ordinarily reacted in the laboratory even with the dilute acid?
The reaction of sodium metal with water is highly exothermic. Hydrogen gas is liberated and autoignites from the heat. With an acid, even more hydrogen gas is liberated and ignites.
What doe you use rock salt for?
Sodium chloride is used to prepare sodium hydroxide, hydrogen, chlorine, sodium, for deicing, in paper industry, in the foods industry etc.
What are the products of sodium chloride?
Sodium chloride is NaCl. Sulfuric acid is H2SO4.
What elements do potassium reacted with?
sodium
What the substance name for CO3HNa?
The substance name for CO3HNa is sodium hydrogen carbonate, also known as baking soda.
When sodium metal in water produces hydrogen gas is it a physical property or a chemical property?
The reaction of sodium metal with water to produce hydrogen gas is a chemical property. This is because a new substance (hydrogen gas) is formed as a result of a chemical reaction between sodium and water.
What happens when sodium is reacted with water?
When sodium reacts with water, it violently fizzes and releases hydrogen gas. The reaction generates heat and forms sodium hydroxide as a product. The released hydrogen gas can ignite or even explode if in a confined space.
