(Don't forget to balance it)
The precipitate here has to be 2NaCl, as Ca(CO3)2 technically dissolves.
Marble, CaCO3 will not usually scratch glass, but maybe a very soft glass. Marble has a hardness of 3 to 4, whereas glass is 4.5 to 6. (in a relative hardness scale.)
Limestone/chalk. Limestone has been subjected to heat and/or pressure, it metamorposes into marble. Both limestone and marble are calcium carbonate (CaCO3). Its just that the internal physical structure of limestone is altered.
The balanced equation is :- Na2CO3 + CaCl2 = 2NaCl + CaCO3
CaCO3 + 2NaCl ------> CaCl2 + Na2CO3
First it's CaCl2, with a lowercase L, not an i. The balanced equation is: Na2CO3(aq) + CaCl2(aq) --> 2NaCl(aq) + CaCO3(s)
You get 1 Mole Of Calcium Carbonate "Chalk", along with 2 Moles of Sodium Chloride "Salt" Na2CO3 + CaCl2 -------------> CaCO3 + 2NaCl
Na2CO3 + CaCl2 >> 2NaCl + CaCO3
The overall equation is: CaCO3(s) + 2NaCl (aq) Na2CO3(aq) + CaCl2(aq),
Precipitate because you're making a solid out of two liquids.
Calcium chloride reacts with sodium carbonate to from sodium chloride and calcium carbonate. This is a double displacement reaction. Skeleton equation: CaCl2 + Na2CO3 -> NaCl + CaCO3 Balanced equation: CaCl2 + Na2CO3 -> 2NaCl + CaCO3
Yes, forming grey precipitate calcium will replace sodium and form calcium carbonate and sodium will bond with chlorine as: CaCl2(aq) + Na2CO3(aq) --> CaCO3(s) + 2NaCl(aq)
Only chemical formulas, not if they are reacting. Na2CO3 and CaCl2
The answer is TWO (2)Na2CO3 + CaCl2 --> 2 NaCl + CaCO3
CaCl2 (aq) + Na2CO3 (aq) --> 2NaCl (aq) + CaCO3 (s) This is called a preciptation reaction
