Because it's a base, and will react with your dead skin, effectively exfoliating it.
The molar mass of sodium hydrogen carbonate (NaHCO3) is approximately 84 grams per mole. Therefore, the mass of 1.00 mole of sodium hydrogen carbonate would be 84 grams.
No, You would need a weak acid so the solution would be acidic
Aluminum hydrogen carbonate is written as Al(HCO3)3.
assuming you mean sodium plus iron II carbonate, the products are iron plus sodium carbonate. iron is a transitional metal which can make +2 or +3 ions, and YOU need to state that in your word equation. there no such thing as iron carbonate, but there is such thing as iron II carbonate and iron III carbonate
Since it is a double displacement and the products of the reaction would be sodium nitrate and calcium carbonate, the precipitate would be calcium carbonate. This is because this reaction is a solubility based reaction, and sodium nitrate is a soluble compound (every metal is soluble in nitrate, and sodium dissolves in almost everything too). Whereas calcium carbonate is insoluble, and therefore will remain solid and form the precipitate.
It would have to be Na(HCO3)2 But no such thing exists.This would require sodium to form a 2+ ion.It can only form a 1+ ion.The real formula for sodium hydrogen carbonate is NaHCO3 .This would be sodium I hydrogen carbonate, though the roman numeral is not needed in this case.
The molar mass of sodium hydrogen carbonate (NaHCO3) is approximately 84 grams per mole. Therefore, the mass of 1.00 mole of sodium hydrogen carbonate would be 84 grams.
When a solution of sodium hydrogen carbonate is heated, it will decompose to form sodium carbonate, water, and carbon dioxide gas. This decomposition reaction is characterized by effervescence due to the release of the carbon dioxide gas.
The reaction between sodium hydrogen carbonate and stearic acid would likely produce sodium stearate, water, and carbon dioxide. Sodium stearate is a type of soap that can be used in various applications such as in making cosmetics or cleaning products.
I guess it would be NaOH and CO2. This explains why it is an alkaline buffer
Firstly, they'll react each other forming sodium hydrogen carbonate and sodium chloride. If there is excess HCl, the sodium hydrogen carbonate would further react till sodium chloride and evolve carbon dioxide.
Sodium carbonate solution is alkaline because of the carbonate ion. Sodium ions do not change the pH. However, carbonate, being the conjugate base of a weak acid (carbonic acid/hydrogen carbonate) does affect the pH. The carbonate ions can abstract a proton to form hydrogen carbonate, HCO3-. When the proton is abstracted from water, hydroxide ions form which results in a higher pH (more basic).
When sodium hydrogen carbonate (baking soda) is dissolved in water, it dissociates to form sodium ions, bicarbonate ions, and some carbonate ions. This results in a slightly alkaline solution due to the presence of bicarbonate ions which can act as a buffer. The overall pH of the solution would be around 8.4.
Im not sure which one it is, but its out of these four. 1. Copper oxide -> copper carbonate + carbon dioxide 2. Sodium carbonate -> sodium hydrogen carbonate + oxygen 3. Sodium hydrogen carbonate -> sodium carbonate + water + carbon dioxide 4. Calcium carbonate -> calcium + carbonate I hope this helps you, even a little bit. Haha, now i need to find the answer to this question!
3 x 2 x 23 = 138g
Calcium hydroxide and nitric acid yield calcium nitrate and water. Ca(OH)2 + 2HNO3 --> Ca(NO3)2 + 2H2O
If you mix sodium carbonate and water, you would observe that the sodium carbonate dissolves in the water. This is because sodium carbonate is highly soluble in water. The solution may also become slightly warm due to the dissolution process.
