Because they will react with each other "chalk up" the line. It'll look white.
I know cause I've done it :)
Calcium carbonate and sodium chloride are formed. CaCl2 + NaHCO3 = CaCO3 + 2 NaCl + H2) + CO2
not sure
Sodium bicarbonate, with four elements: sodium, hydrogen, carbon, and oxygen. Calcium chloride has only two elements and the others listed have three elements each.
Salt (sodium chloride) and limestone (calcium carbonate).
The reaction equation for sodium bicarbonate (NaHCO3) and calcium chloride (CaCl2) is: 2 NaHCO3 + CaCl2 -> CaCO3 + 2 NaCl + H2O + CO2 This reaction results in the formation of calcium carbonate (CaCO3), sodium chloride (NaCl), water (H2O), and carbon dioxide (CO2).
Sodium, Na. Potassium, K. Calcium, Ca. Magnesium, Mg. Chlorine, Cl. Bicarbonate should be CO2. Phosphorus, P.
When calcium hypochlorite and sodium bicarbonate react, they produce calcium carbonate, sodium chloride, and water. This reaction is commonly used in swimming pool chlorination systems to release chlorine gas for disinfection purposes.
When calcium chloride dissolves, it is rather exothermic (which makes it a good deicer for sidewalks). After mixing: the sodium and chloride ions will remain in solution and do nothing. The bicarbonate and calcium will react in a strange way. Ca2+ + 2 HCO3- → CaCO3 + H2CO3 As the calcium carbonate drops out of solution, the equilibrium of this reaction is further driven off to the right thus creating more carbonic acid. Carbonic acid easily decomposed to form water and carbon dioxide. H2CO3 → H20 + CO2 So, when you mix calcium carbonate and sodium bicarb, you get: Carbon dioxide gas, calcium carbonate solid, water and sodium and chloride ions.
Examples are: sodium chloride, potassium chloride, calcium chloride, ammonium chloride, ammonium phosphates, sodium carbonate, sodium sulfate, magnesium sulfate, cooper sulfate, magnesium chloride.
CaCl2 + 2NaHCO3 --> 2NaCl + CaCO3 +CO2 +H2O
sodium, potassium, chloride, calcium, magnesium, bicarbonate, phosphate, and sulfate
Calcium Chloride is a complete salt.There are no replaceble H+ or OH-.So it does not react with NaHCO3.So there is no change of mass.
