I need to know if this is balanced/unbalanced MgCO3+2HCl=MgCl2+H2CO3?
Check the values on both sides: _______right___left Mg______1_____1 Cl_______2_____2 H________2____2 CO3_____1_____1 It's balanced since all of the items are equal on both sides.
Chemistry HW : Balance equation and moles?
1. Determine the Products and Balance the following : How do you figure out the other side? Mg(s) + HCl (aq) -----> 2. Balance the following equations Na CO3 + Mg (NO3) ---> Mg CO3 + Na NO3 Can you show me please? Im confused... it is balanced right ?How is this not ?!! 3. A mixture of hydrazine (N2H4) and hydrogen peroxide (H2O2) is used as fuel for rocket engines. These two substances react as shown by the equation: N2H4 + 2H2O2 N2 + 4H2O ---How do you do this??!!!----What mass of N2H4 in grams is needed to react with completely with 35.0g of H2O2? List the mole to mole relationship: Are these right? 1 mole of N2H4: 2 moles of H2O2 1 mole of N2H4: 1 mole of N2 1 moles of N2H4: 4 mole of H2O 2 moles of H2O2: 1 mole N2 2 moles of H2O2: 1 mole H2O 1 moles of Na: 4 moles of H2O I dont want people doing my homework, I just wan to understand. Can somebody show me work and help me understand for these 3 problems thanks !!
What is the Ionic equation for the reaction between calcium carbonate and hydrochloric acid?
Calcium carbonate dissolves into Ca(2+) and carbonate (CO3)(2-) ions. Hydrochloric acid dissolves into H(+) and Cl(-). When Ca(2+) and Cl(-) form CaCl2, it dissolves again (it is very soluble.) When H(+) combines with carbonate (CO3)(2-), you get a mix of ions, but if you have enough acid, you primarily get H2CO3, carbonic acid. This decomposes into H2O liquid and CO2 gas, which is what happens in your soda when you open it and relieve the pressure—it makes bubbles of CO2. Since CaCl2 is soluble, Ca(2+) and Cl(-) are spectator ions. You can cancel them out of the total reaction to get the net ionic equation. The net equation is then 2H(+) +CO3(2-) → H2O (liquid) and CO2 (gas).
Simple chemistry equation?
Mg 2+, CO3 2-, H +, and Cl - so, MgCl2 + H2CO3
Ionic Equations?
Ionic equations start from the usual balanced chemical equation. Any compound that is aqueous in the balanced equation and is a strong electrolyte (i.e. dissociates into ions in a wate solution) is written as separated ions, since this is a better depiction of the actual species present in the reaction mixture. Any species that is a solid, liquid, or gas in the balanced equation does not change in the ionic equation. So for your two reactions: The first reaction is an acid-base reaction that forms magnesium chloride and carbonic acid (H2CO3), but carbonic acid spontaneously decomposes to water and CO2. The balanced equation is: MgCO3 (s) + 2HCl (aq) --> MgCl2(aq) + H2O (l) + CO2 (g) The ionic equation is: Mg(CO)3 (s) + 2H+ (aq) + 2Cl- (aq) --> Mg2+ (aq) + 2Cl- (aq) + H2O (l) + CO2 (g) The second reaction is, well, not a reaction, since barium sulfite isn't going to react with nitric acid. I guess you could write this: Balanced equation HNO3 (aq) + BaSO3 (s) --> no reaction Ionic equation: H+ (aq) + NO3- (aq) + BaSO3 (s) --> no reaction At least the first example will help you with ionic equations.
Magnesium Carbonate + Hydrochloric Acid reaction?
For the reaction: MgCO3 (s) + 2HCL (aq) --> MgCl2 (aq) + CO2 (g) +H2O (l) Is this an appropriate description? "The hydronium ions in the hydrochloric acid donate protons to the carbonate ions, producing the hypothetical carbonic acid, H2CO3, which, if it is ever formed, immediately decomposes into carbon dioxide and water. In this process, the carbonate ion is acting as a base, of course. This is similar to how all carbonates would react."
