When sodium chloride (NaCl) is heated with concentrated sulfuric acid (H₂SO₄) in the presence of manganese dioxide (MnO₂), a chemical reaction occurs that produces manganese(II) chloride (MnCl₂), sodium bisulfate (NaHSO₄), water (H₂O
What happens when calamine is heated? When heating calamineit decomposes into zinc oxide and carbon dioxide. You can tell when the calamine is hot because it turns from white to yellow, but when it is cooled, it turns back to white. This can be a method of seeing when the reaction is ...
Write the chemical equations to show what happens when ethanol reacts with ethanoic acid in the presence of sulphuric acid? View Solution What happens when (i) ethanol burns in air. (ii) ethanol reacts with sodium metal. (iii) ethanol is oxidised with chromic anhydride in glacial ethanoi...
What happens when ethanol reacts with: a) sodium? b) potassium permanganate solution? What is 'Fremy's salt'? Write two uses of NaCl. How do I tell if something can dissolve into another? For example, how would I tell if a solvent will dissolve in salt, NaCl?
A separation process that depends on differing abilities of substances to form gases is called what? How is the mixture of alkanes separated by fractional distillation? What happens when sodium chloride solution is heated? Does a salt solution show the Tyndall effect?
Denaturation ("changing the nature") happenswhen protein molecules unravel from their naturally coiled state. With eggs, this happens most frequently when they're heated or beaten, but denaturation can also be prompted by salt, acids (such as vinegar), alkalies (such as baking soda), and free...
when the engine is cold). In other words, diesel is heated up by being squeezed, while gasoline is lit with fire. Furthermore, gasoline is often mixed with as much as 10-percent ethanol, a highly flammable organic compound used as a biofuel additive. Ethanol makes gasoline even more ...
and then the agave fiber is left in an open-air environment so that wild yeasts in the air can kick-start the fermentation process. Fermentation takes anywhere from three days to a week depending once again on the climate and is “where the magic happens” in determining the complex flavors...
Distillation is the process of separating components based on their different boiling points. Reflux is the return of process fluid after it has been cooled, condensed, heated or boiled. The two processes use similar equipment.
When that happens, the fuel mixture autoignite creating the destructive multiple flame fronts.Mild detonation can occur in almost any engine and won't cause any harm. But prolonged heavy detonation is bad news because it hammers the pistons and rings. If the problem is not corrected, severe ...
