Item 17: Question In acidic solution, dichromate is reduced to the chromic ion by this half-reaction Cr₂O7² + 14H+ + ne² → 2Cr³+ + 7H₂0 What is the value of n for this process?

Is there any way that I can get some assistance with parts E, F and G? What are also the types of reaction?

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.

1. How does chemical reaction seen in real life situations? And what are their importance in real life situations?

How much heat will be generated when 75.00 mL of 0.688 M perchloric acid solution reacts with 50.00 mL of 0.544 M calcium hydroxide solution?

please help me answer these questions.

Describe the characteristics of single replacement reaction, how it is identified, and what determines if this reaction will occur. Give an example in your response.   (pls write neatly and clearly)
