The salt calcium nitrate, Ca(NO3)2, can be prepared by reacting calcium carbonate with dilute nitric acid, HNO3.(a) Write the balanced chemical equation for the reaction between calcium carbonate and dilute nitric acid.… [2](b) Describe a positive test for the gas produced in this reaction...
I am sure solid calcium is formed (thus reduced). But how can it be reduced when the compounds used for the combustion are oxidizing agents? I am considering C2H2(g)/O2(g). [Ca(H2O)6]2+(aq) + C2H2(g)/O2(g) → CaO(s) + 6H2O(g) + C2H2(g)/O2(g) Eq. 3 Remark: When h...

Re: Reaction kinetics of acid nitric 54 wt.% and calcium carbonate solution «Reply #1 on:May 12, 2017, 07:41:28 AM » I would start with a balanced chemical equation, and the ideal gas laws. The gas laws are approximations, and not really accurate for the quantities from a product...
The only source of dietary calcium was calcium carbonate. All experimental diets were formulated with a calcium-free mineral mix and a VD-free vitamin mix. The dietary content of phosphate and vitamin K1 (phylloquinone) in all groups were 3000 mg/kg and 750 µg/kg diet, respectively. ...
An industrial process makes calcium oxide by decomposing calcium carbonate. Which of the following is not needed to calculate the mass of calcium oxide that can be produced from 4.7 kg of calcium carbonate? a. The balanced chemical equation. b. Molar mas ...

Calcium Carbonate USP CaCO3 100.09 Carbonic acid, calcium salt (1:1) Calcium Carbonate, dried at 200 for 4 hours, contains calcium equivalent to not less than 98.0 percent and not more than 100.5 percent of CaCO3. Packaging and storage— Preserve in well-closed containers. ...
Calcium phosphate is usually prepared by reacting calcium hydroxide (Ca(OH)₂) with phosphoric acid (H₃PO₄) or by heating a mixture of calcium carbonate (CaCO₃) and ammonium phosphate ((NH₄)₃PO₄). Calcium phosphate is generally considered non-toxic and is safe for use in...
It is practically insoluble in water, but is readily soluble in dilute hydrochloric and nitric acids. It is insoluble in alcohol. Dibasic calcium phosphate is produced by the reaction of phosphoric acid, calcium chloride, and sodium hydroxide. Calcium carbonate can be used in place of the ...
