1) when solid fe metal is put into an aqueous solution of niso4, solid ni metal and a solution of feso4 result. write the net ionic equation for the reaction. 2)when aqueous solutions of sodium fluoride and hydroiodic acid are mixed, an aqueous solution of sodium iodide and hydrofluoric acid results. write the net ionic equation for the reaction. use h+ for the hydronium ion.

Electrons are extremely important to what area of technology? a) anti-aging research b) household product development c) electronics d) drug discovery

Both josef loschmidt and amedeo avogadro contributed to our understanding of basic molecular numbers, sizes, and reaction ratios. neither scientist discovered “avogadro’s number” in the form we use it today (6.02 x 10 23). still, there’s a controversy over the name. research the contributions from these two scientists and read about how avogadro’s number got its name. briefly state what you think this number should be called, providing key details of each scientist’s contributions to this concept and a solid rationale for your case in naming the number.

Amixture that has two or more substances that are spread out evenly is called a. compound b. heterogeneous c. substance d. homogeneous
