A pair of students in chemistry lab are performing chemical reactions lab. They mix zinc nitrate with sodium carbonate. The reaction produces a precipitate in the bottom of their test tube. The lab manual states, "All common nitrates (NO3) are soluble. All carbonates (CO3)2- are insoluble except with group 1 or NH4* ions." Select the chemical reaction that shows the correct, balanced chemical reaction between zinc nitrate and sodium carbonate. Zn(NO3)2 (aq) + N22CO3 (aq) → No reaction Zn(NO3)2 (aq) + N22CO3 (aq) → ZnNa2 (s) + CO3(NO3)2 (aq) Zn(NO3)2 (aq) + Na2CO3 (aq) → ZNCO3 (s) + 2 NaNO3 (aq) Zn(NO3)2 (aq) + Na2CO3 (aq) -→ ZNCO3 (aq) + 2 NANO3 (s)

Use this graph to answer the questions in the table below. 0.30- 0.269 0.25- 0.20- M 0,15- 0.10- 0.05 - 500 1000 1500 2000 2500 3000 seconds created x10 Is H,O, being created or destroyed by the chemical O destroyed reaction? neither created nor destroyed If H,O, is being created or destroyed, what is the rate at which it is being created or destroyed 700 seconds after the reaction starts? Round your answer to 2 significant digits. Also be sure your answer has the correct unit symbol. If H,O, is being created or destroyed, what is the average rate at which it is being created or destroyed during the first 700 seconds of the reaction? Round your answer to 2 significant digits. Also be sure your answer has the correct unit symbol.

How can we answer these questions on solution stoichiometry and equilibrium?
Consider a double replacement reaction between Zinc (ll) chloride and sodium hydroxide: ZnCl2+NaOH ==> Complete the chemical equation by: 1. Rewriting it to include electrically-neutral ionic product formulas for each formula. To clarify instead of just writing the product formulas rewrite the entire equation. Concerning the "electrically neutral" part, you are reminded that if for example, Na + Cl2 ==> were your reactants, you would not predict NaCl2 as a chemical product because that is not an electrically neutral compound formula. The Na would have a +1 charge and, the Cl would have a -1 charge, 2 (-1) charges would give an overall -2 charge which would not produce an overall 0 charge. 2. Balance it. 3. Add subscripts (aq, I, s, or g) to show how the reactants combine and which product will precipitate to be collected as a solid. 4. Provide subscripts for both reactants and both products.
3. For each reaction below, (f) write a balanced reaction equation, including proper state symbols, and (ii) name the type of reaction that occurs. Note: More than one type of reaction may apply to the same reaction equation. a. zinc metal reacts with aqueous copper(II) sulfate to form copper metal and aqueous zinc(II) sulfate b. aqueous sodium sulfide and aqueous lead(II) acetate form aqueous sodium acetate and solid lead(II) sulfide C. solid sodium bicarbonate is heated to form carbon dioxide gas, liquid water, and solid sodium carbonate d. solid magnesium and diatomic nitrogen gas react to form solid magnesium nitride e. sulfuric acid and aqueous potassium hydroxide react to form aqueous potassium sulfate and liqud water
I don’t need an explanation, just an answer.
Give clear detailed Solution.. don't give Handwritten answer
Assuming you started with 3.23 g of sodium bicarbonate and your actual yield of solid product is 1.20g, which reaction is more likely to be the correct one?
