Because carbonic acid is diprotic.
When titrating Na2CO3 with H2SO4, the acid-base reaction that occurs is: Na2CO3 + H2SO4 → Na2SO4 + H2CO3 The carbonate ion (CO3^2-) in Na2CO3 reacts with the hydrogen ion (H+) in H2SO4 to form carbonic acid (H2CO3), which then decomposes into water (H2O) and carbon dioxide (CO2). The endpoint of the titration is reached when all the Na2CO3 has reacted with the H2SO4.
The balanced chemical equation is Ca(OH)2 + Na2CO3 + 2HNO3 → Ca(NO3)2 + 2NaOH + CO2 + H2O
2NH4Cl + Na2CO3 --> 2NH3 + CO2 + H2O + 2NaCl
To solve this problem, we need to use the balanced chemical equation between HCl and Na2CO3. From the equation, we can see that it is a 1:2 ratio for HCl to Na2CO3. Therefore, we need twice the volume of 0.161 M Na2CO3 to react completely with HCl. Calculate the volume of HCl required by multiplying the volume of Na2CO3 by 2.
The chemical equation for sodium carbonate is Na2CO3. It is made up of two sodium atoms, one carbon atom, and three oxygen atoms. When dissolved in water, it dissociates into sodium ions (Na+) and carbonate ions (CO3^2-).
When titrating Na2CO3 with H2SO4, the acid-base reaction that occurs is: Na2CO3 + H2SO4 → Na2SO4 + H2CO3 The carbonate ion (CO3^2-) in Na2CO3 reacts with the hydrogen ion (H+) in H2SO4 to form carbonic acid (H2CO3), which then decomposes into water (H2O) and carbon dioxide (CO2).

2, a sack in the end zone is considered a safety which is 2 points
The balanced chemical equation is Ca(OH)2 + Na2CO3 + 2HNO3 → Ca(NO3)2 + 2NaOH + CO2 + H2O
The answer is TWO (2)Na2CO3 + CaCl2 --> 2 NaCl + CaCO3
The end points are 7 and 2.
A line segment is between two end points
The balanced chemical equation for the reaction between copper(II) nitrate (Cu(NO3)2) and sodium carbonate (Na2CO3) is: Cu(NO3)2 + Na2CO3 → CuCO3 + 2NaNO3
2NH4Cl + Na2CO3 --> 2NH3 + CO2 + H2O + 2NaCl
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.
First it's CaCl2, with a lowercase L, not an i. The balanced equation is: Na2CO3(aq) + CaCl2(aq) --> 2NaCl(aq) + CaCO3(s)
The shape that has 2 end points is known as a line segment. A line segment is a line that can go on forever, but it has a start point and an end point, no matter where it stops.
