INSTRUCTIONS:
For each word equation write a balanced chemical formula equation.
1. Solutions of potassium hydroxide and aluminum nitrate were mixed together yielding a
white ppt and a soluble salt.
2. Drinking alcohol, ethanol (CH3CH2OH), burns completely in oxygen gas to give two prod-
ucts only: water vapor and carbon dioxide gas.
3. Aqueous chlorine reacts with a solution of sodium iodide to give sodium chloride and ele-
mental iodine in solution.
4. Solutions of phosphoric acid and calcium hydroxide neutralize each other. A white ppt is
observed.
5. HgO solid (mercuric oxide) when heated breaks down into its elements.
6. Sodium metal reacts with oxygen gas to give sodium oxide.
7 Debrecitim carbonate crystals react with hydrochloric acid to give water and a gas that

What does x represent in the formula for the compound xcl4?

An alkaline battery produces electrical energy according to the following equation. zn(s) + 2 mno2(s) + h2o(l) zn(oh)2(s) + mn2o3(s) (a) determine the limiting reactant if 17.5 g zn and 31.0 g mno2 are used. (type your answer using the format ch4 for ch4.) (b) determine the mass of zn(oh)2 produced. _ g

Many reactions take place in aqueous solution. when potential reactants are mixed, a reaction will occur if there is some driving force that favors the formation of products. it is often convenient to categorize reactions in terms of these driving forces: precipitate formation, in which an insoluble solid is formed, weak electrolyte formation, as in a neutralization reaction involving water, or transfer of electrons, as in a redox reaction. these reactions can be represented by full molecular equations, which contain all species in the reaction mixture, or by net ionic equations, which show only the species that actually undergo a change. the latter does not contain the spectator ions, which do not undergo a net change or do not take part in the reaction. part a when the following two solutions are mixed: k2co3(aq)+fe(no3)3(aq) the mixture contains the ions listed below. sort these species into spectator ions and ions that react. drag the appropriate items to their respective bins. view available hint(s) spectator ions ions that react part b what is the correct net ionic equation, including all coefficients, charges, and phases, for the following set of reactants? assume that the contribution of protons from h2so4 is near 100 %.ba(oh)2(aq)+h2so4(aq)→ express your answer as a chemical equation. view available hint(s) nothing provide feedback
