Consider the reaction of iron (III) chloride and sodium hydroxide to form iron (III) hydroxide and sodium chloride. Which of the following depicts the balanced molecular equation? (consider the solubility rules when making your choice) [Multiple Choice: Choose the best option from the choices below] Consider the reaction of iron (III) chloride and sodium hydroxide to form iron (III) hydroxide and sodium chloride. Which of the following depicts the balanced molecular equation? (consider the solubility rules when making your choice) FeCl3 (aq) + 3NaOH (aq) --> Fe(OH)3 (s) + 3NaCl (aq) FeCl3 (aq) + NaOH (aq) --> Fe(OH)3 (s) + NaCl (aq) 3FeCl3 (aq) + NaOH (aq) --> 3Fe(OH)3 (s) + NaCl (aq) FeCl3 (aq) + 3NaOH (aq) --> Fe(OH)3 (aq) + 3NaCl (s)

One way the U.S. Environmental Protection Agency (EPA) tests for chloride contaminants in water is by titrating a sample of silver nitrate solution. Any chloride anions in solution will combine with the silver cations to produce bright white silver chloride precipitate. Suppose an EPA chemist tests a 250. mL sample of groundwater known to be contaminated with iron(III) chloride, which would react with silver nitrate solution like this: FeCl,(aq) + 3 AgNO3(aq) 3 AgCl(s) + Fe(NO,),(aq) → The chemist adds 17.0 mM silver nitrate solution to the sample until silver chloride stops forming. He then washes, dries, and weighs the precipitate. He finds he has collected 8.2 mg of silver chloride. Calculate the concentration of iron(III) chloride contaminant in the original groundwater sample. Round your answer to 2 significant digits. mg L

Please answer the question clear enough to read, with the states of matter by each formula such as solid, gas, etc

What are 5 ways to identify chemical reaction?

Choose a chemical reaction that is used in industry, research, or nature. DO NOT USE the photosynthesis process or the cellular respiration process. Photosynthesis and cellular respiration are not single chemical reactions; they are each a series of chemical reactions. For the reaction that you choose: 1) Write the balanced chemical equation for the reaction (include the phases). 2) What is/are the reactant(s)? 3) What is/are the product(s)? 4) Why is this reaction important in either industry, research, or nature?

FIRST, write the balanced equation that represents each reaction. THEN, classify each reaction. a) Hydrochloric acid neutralizes barium hydroxide b) Propane (C3H8) is burned. c) Chromium and oxygen form chromium (III) oxide. (Skip classifying this reaction; we will learn this reaction next week) d) Ammonium carbonate and barium chloride are mixed; barium carbonate precipitates.
