What acid and what base would react in aqueous solution so that the following salts appear as products in the molecular equation? Does Jerry Seinfeld have Parkinson's disease? Using coefficients, we can balance chemical equations so that the equation demonstrates conservation of atoms. Calcium iodide is an inorganic compound that is made of calcium and iodine. Find out more about how we use your information in our Privacy Policy and Cookie Policy. Select Page. 2Na3PO4 + 3Ca(NO3)2--->6NaNO3 + Ca3(PO4)2its a double displacement reaction. In the hydrogen wasn't properly balanced. If you do not find the exact resolution you are looking for, then go for a native or higher resolution. Each halogen can replace the … To balance out the charge, we need two iodines. Chemistry. Write a balanced molecular equation and a net ionic equation for his reaction . SETS. Answer:Br2 + CaI2 = CaBr2 + I2Explanation:Disclaimer: Not sure what you're asking, however, I will provide you with the full balanced equation. Moles Of Silver Iodide: Mol ... 3. calcium chloride and sodium carbonate. Calcium iodide, 99%. AKOS015904002. So your answer is CaI2. 1 Answer. Favorite Answer. Hint: Remember to balance the electrons! Its properties are similar to those for related salts, such as calcium chloride. The reason for this is because both products are soluble ionic compounds whos ions dissolve in the water. Since the transfer of electrons for both half-reactions are already equal, we will simply add the two equations to obtain the complete reaction for the formation of calcium iodide. Carbon dioxide, CO 2, was also pro-duced in this decomposition reaction. Calcium iodine is formed when calcium reacts with iodine. Reaction of calcium with the halogens. a. Nickel + Magnesium chloride —¥ b. Calcium + Copper(ll)bromide —+ Cacs) c. Potassium + Aluminum nitrate —Y d. Coefficients are used to add more of the missing atoms. Update: I got answer but actually it wasn't properly balanced. COVID-19 is an emerging, rapidly evolving situation. "Br"_2+"2NaI"rarr"I"_2+"2NaBr" This is a single replacement (single displacement) reaction involving the halogens (group 17/VIIA on the periodic table), rather than metals. 0 0.

Answer (1 of 2): Calcium is a chemical compound and its molecular formula is CaO. 1 decade ago. Chemistry. Balance equation. The law of conservation of atoms says that no atoms are lost or … Calcium iodide (chemical formula CaI2) is the ionic compound of calcium and iodine. Component Compounds: CID 24841 (Hydriodic acid) CID 5460341 (Calcium) Dates: Modify . The. Lv 7. Henri Moissan first isolated pure calcium in 1898 by reducing calcium iodide with pure sodium metal:[3], Calcium iodide can be formed by treating calcium carbonate, calcium oxide, or calcium hydroxide with hydroiodic acid:[4], Calcium iodide slowly reacts with oxygen and carbon dioxide in the air, liberating iodine, which is responsible for the faint yellow color of impure samples. Yahoo is part of Verizon Media. CaI 2 + 2H 2 O Ca (OH) 2 + 2HI [ Check the balance ] Calcium iodide react with water to produce calcium hydroxide and hydrogen iodide. It can be used for pH correction of water or for its disinfection (with excess lime). you have the formula for sulfuric wrong and lose the parentheses. Favourite answer. More importantly, lime has been used for a very long time to produce calcium carbonate by reaction with carbon dioxide. d. What type of reaction(s) is/are being represented by the chemical reaction you wrote in part (a)? NaH₂PO₄ → NaPO₃ + H₂O. This reaction can be written as follows in a balanced form: (s) + 2KCl(aq) → Ca (s) + 2 (aq) The equation now on the right and left side of the reaction are both balanced and equal. cancel(Ca^(2+)(aq)) + 2Cl^(-)(aq) + 2Ag^+(aq) + cancel(2NO_3^(-)(aq))rarr2AgCl(s) + cancel(Ca^(2+)(aq)) + cancel(2NO_3^(-)(aq)) As you can see, we are left with 2Cl^(-)(aq) + 2Ag^+(aq)rarr2AgCl(s) Side Note: Questions like these usually ask for the Spectator Ions, which is simply the crossed out ions we saw … Hence the chemical equation is fully balanced.
