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 chemical equation for the reaction between Na2CO3 and CaCl2 to form CaCO3 and NaCl is: Na2CO3 + CaCl2 -> CaCO3 + 2NaCl. Therefore, the coefficients are 1, 1, 1, and 2 for Na2CO3, CaCl2, CaCO3, and NaCl respectively.
CaCO3 + 2NaCl ------> CaCl2 + Na2CO3
The balanced equation for the reaction is: Na2CO3 + CaCl2 -> 2NaCl + CaCO3.
The balanced equation for the reaction between CaCl2 and Na2CO3 is: CaCl2 + Na2CO3 -> CaCO3 + 2 NaCl
The chemical reaction between Na2CO3 (sodium carbonate) and CaCl2 (calcium chloride) is: Na2CO3 + CaCl2 -> CaCO3 + 2NaCl This reaction forms calcium carbonate (CaCO3) and sodium chloride (NaCl).
When Na2CO3 and CaCl2 are mixed, a double displacement reaction occurs. The sodium ions from Na2CO3 switch places with the calcium ions from CaCl2 to form two new compounds: CaCO3 (calcium carbonate) and 2NaCl (sodium chloride). This reaction is also known as a precipitation reaction, as calcium carbonate is insoluble in water and will form a solid precipitate.
The balanced chemical equation for the Solvay process is: 2 NaCl + CaCO3 → Na2CO3 + CaCl2
The balanced chemical equation for the reaction between sodium carbonate (Na2CO3) and calcium chloride (CaCl2) is 2Na2CO3 + 3CaCl2 -> CaCO3 + 2NaCl + 2CaCl2. This reaction results in the formation of calcium carbonate (CaCO3), sodium chloride (NaCl), and excess calcium chloride (CaCl2).
The reaction between Na2CO3 and CaCl2 is a double displacement reaction, also known as a precipitation reaction. This reaction forms insoluble CaCO3 as a precipitate, while NaCl remains in solution.
When you mix Na2CO3 (sodium carbonate) and CaCl2 (calcium chloride), you would get CaCO3 (calcium carbonate) and NaCl (sodium chloride) as the products in a double displacement reaction. The balanced chemical equation is: Na2CO3 + CaCl2 → CaCO3 + 2NaCl.
CaCl2 (aq) + Na2CO3 (aq) --> 2NaCl (aq) + CaCO3 (s) This is called a preciptation reaction
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
