Solve this stoichiometry problem solve the following problem showing all of your work and including all units. you can solve the problem in several steps or as a tandem conversion problem. how many grams of br2 are needed to completely convert 15.0 g al to albr3 ? al (s) + br2 (l) --> albr3 (hint: the equation is not balanced)

According to the tide table below what time of day will the highest tide occur?

Silver tarnishes as silver metal reacts with hydrogen sulfide, h2s, in the air. in this reaction, dark silver sulfide, au2s, covers the surface of silver. when silver is polished, this coating of silver sulfide can be removed from the surface. this makes the silver shiny again. enter the coefficients that balance the tarnishing reaction equation. (type 1 for no coefficient.)

Ageochemist examines a piece of metal that he found in the soil. he performs tests to identify the metal from its density, electrical conductivity, and melting point. which statement best describes his investigation? a. he is determining physical properties that are sufficient to identify the metal.b. he is determining chemical properties that are sufficient to identify the metal.c. he is determining physical properties that are insufficient to identify the metal.d. he is determining chemical properties that are insufficient to identify the metal.
