Trisha and her lab partner were conducting a variety of experiments to produce gases: hydrogen, oxygen, and carbon dioxide. in one experiment, they added a piece of magnesium ribbon to 10 milliliters of hydrochloric acid. they observed bubbles being produced and did a variety of tests to identify the escaping gas; it proved to be hydrogen the reaction is represented by the following equation: mg + 2hcl → mgcl2 + h2(g) trisha and her lab partner filled a beaker with 150 milliliters of a 0.10 m hcl solution. how many moles of hcl are in the beaker? remember, molarity = moles liter . a) 0.015 mol hcl b) 0.150 mol hcl c) 6.67 mol hcl d) 15 mol hcl

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
