yes
reaction betwen sodiumbisulphite and hydrogen peroxide
The white you see is many microscopic bubbles of oxygen released by a reaction between the Hydrogen Peroxide (H2O2) and your saliva.
have any reaction between calcium carbonate & milk
They are the same chemical.
There is no reaction between phenol and sodium carbonate
reaction betwen sodiumbisulphite and hydrogen peroxide
it makes hydrogen
Hydrogen Peroxide decomposes in oxygen gas and water.
There is no reaction between H2O2 and K2Cr2O7 because both are oxidants.
a
Any chemical reaction between these compounds.
The white you see is many microscopic bubbles of oxygen released by a reaction between the Hydrogen Peroxide (H2O2) and your saliva.
No reaction occurs between the acidified hydrogen peroxide and the other halide ions, because the hydrogen ions involved in both cases are in the same group. For a reaction to occur it needed to have an element that is more reactive than hydrogen.
endothermic because it absorbs energy, and not releasing it
Temperature
Na2CO3 + 2HCl ----> 2NaCl + H2O + CO2
