What is the name of the following element ZnCI2?
ZnCl2 is the chemical formula of zinc chloride.
How do you write the correct coefficients in correct order after this equation has been balanced ai2 co3 3 plus znci2 znco3 plus aici3?
First off, you have the equation written wrong... those are Ls not Is. so it's Al2(CO3)3 + ZnCl2 = ZnCO3 + AlCl3 The balanced form of that equation is Al2(CO3)3 + 3 ZnCl2 = 3 ZnCO3 + 2 AlCl3 So the coefficients are 1,3,3,2
Examples of double-replacement reaction?
Na2SO4 + CaCl2 ----> NaCl + CaSO4 Pb(NO3)2 + KI ----> PbI2 + KNO3 NaOH + CuSO4 ----> Na2SO4 + Cu(OH)2 K2CO3 + FeSO4 ----> K2SO4 + FeCO3 CH3COONa + CuCl2 ----> (CH3COO)2Cu + NaCl HNO3 (aq) + KOH (aq) ----> H2O (I) + KNO3 (aq) Ba(OH)2(aq) + 2HCIO4(aq) ----> Ba(CIO4)2(aq) + 2H2O(I)

In the process of electrolysis current can flow through liquid because?
in the chemical equations zn 2hcl znci2 h2 the reations are
What does zn h2ci2-----znci2 h2o mean?
You should have written this equation as Zn + H2Cl2 --> ZnCl2 + H2O. Regardless, this equation is meaningless. There is no h2ci2. The ci is actually cl (for chlorine), and should be written in as Cl. There is HCl, which is hydrochloric acid, or hydrogen chloride. The fact that oxygen appears on the right side of the equation but not on the left side means that this equation is basically meaningless. What is a possibility is Zn + 2HCl --> ZnCl2 + H2, which means zinc and hydrochloric acid react to produce (yield) zinc chloride and hydrogen. The symbols for elements are written as capital letters for a single letter, such as H for hydrogen, or as a capital letter followed by a lowercase letter for two letters, such as Cl or chlorine. Also, the numbers written after an element in a chemical formula are subscripts, meaning they are written on the bottom right of the element's symbol. A chemical equation requires a plus (+) symbol in between the reactants on the left side and the products on the right side. Also, all of the elements on one side of an equation must also be on the other side of the equation, in equal numbers. Lastly, an arrow (-->) goes between the reactants and the products, not a straight line. You cannot write a chemical equation as if you were texting. There are rules that everyone follows so we can all understand each other.
Which of the following is not a double-displacement reaction- Zn (s) + 2HCl (aq) -- H2 (g) + ZnCl2 (s)- Ba(OH)2 (aq) + 2HClO4 (aq) -- Ba(ClO4)2 (aq) + 2H2O (l)- NaOH (aq) + HCI (aq) -- H2O (aq) + NaCI (s)- HNO3 (aq) + KOH (aq) -- H2O (I) + KNO3 (aq)?
Zn (s) + 2HCI (aq) -- H2 (g) + ZnCI2 (s) Apex
