Question 1

Now, write the balanced equation for the reaction you just watched in question 4 (same video embedded below). Hint: The reactants are solid copper and aqueous silver nitrate. There are two products in this reactions - one is a solid and one is an aqueous solution of an ionic compound. Copper becomes a +2 ion. Please make sure to use phases for each substance and parentheses (when needed) and subscripts.   https://www.youtube.com/watch?v=P5QlfMRvvF8&feature=emb_title   (1 min 9 sec  video)

Note, all other compounds in the reaction are aqueous (aq). Balance the equation. 4. Zinc chloride reacts with aluminum phosphate to produce zinc phosphate and aluminum chloride. Table #1: work for the above 4 problems. Use your notebook, take a picture of your work, and download it to this document. Make sure you edit the pic for clarity and that your name is written on top of each page.

Looking up one rainy afternoon from lab notebook, your friend Christine (an expert chemist) says this: "Metal sulfides react with strong acids to produce hydrogen sulfide and a salt." Using Christine's statement, and what you already know about chemistry, predict the products of the following reaction. Be sure your chemical equation is balanced! Fe₂S₁(s) + HCl(aq) →]] ☐ ロ→ロ □+ロ NO REACT

ou are asked to weigh 2 g of lithium and add it to 1500 ml of distilled water +2drops of indicator, knowing that the density of water is 1 at room temperaturewhile conducting this experiment. What type of reaction occurs? Write and balance the equation of this reaction. Is there a gas that will be emitted? How can you test that this gas was released

Write the equation for the following reaction given in words. Separate substances with a +, use --> for the arrow. All numbers will be large (no subscripts). When sodium metal reacts with iron(II) iodide, iron metal and sodium iodide are formed.   Balance the chemical equation you wrote in by adding coefficients as necessary. Retype the entire equation with the coefficients

. For each reaction scenario below, predict the products of the reaction, and write a complete balanced chemical equation. If you predict that no reaction will occur, write the reactants, then write NR after the arrow. а. Water undergoes decomposition by electrolysis. b. A table salt (sodium chloride) solution is poured into an aluminum can. с. A copper (II) nitrate solution is combined with an ammonium chromate solution.

There are two different reactions you will study in this experiment: a heat of neutralization and a heat of solution reaction. a. Write the balanced chemical equation for the neutralization reaction. Be sure to include charges and phase changes (if appropriate). b. Write the balanced chemical equation for the heat of solution reaction. Be sure to include charges and phase changes (if appropriate). Equation: NH3(g) + HCl(g) → NH4Cl(s)+ Heat per my instructor:(Question 2 isn't looking for the math behind the reactions, just what the balanced chemical equation will look like. So just write out what chemicals/ions will come together to make the ammonium chloride (use your answer to Q1 as a reference for this). 2a is looking for the balanced chemical equation for ammonia and water and 2b is looking for a balanced chemical equation with ammonia and hydrochloric acid.)

F. Methane and oxygen reactant 1 reactant 2 product 1 product 2 + + chemical reaction: + appearance of reactants and products: evidence of reaction type of reaction: Can you visually observe any of the reactants or products in this reaction? Why or why not? (Bonus) Can you think of any way to test for the presence of any of the products? Describe.

Fluorine gas is bubbled into an iron(III) chloride solution. Chlorine gas is collected and the remaining solution contains iron(III) fluoride.  1.Write the chemical equation. 2.Balance the chemical equation.

Question 4 and 5 please. Ensure that its clear.
