The mixture you separated was a mixture of iron filings, sand, and salt. based on your understanding of matter, is this mixture a homogeneous mixture or heterogeneous mixture? how do you know? homogeneous mixture-the parts are not uniformly mixed homogeneous mixture-the parts are uniformly mixed heterogeneous mixture-the parts are uniformly mixed heterogeneous mixture-the parts are not uniformly mixed

Ase your answer to this question on the information below. hydrocarbons and fissionable nuclei are among the sources used for the production of energy in the united states. a chemical reaction produces much less energy than a nuclear reaction per mole of reactant. the balanced chemical equation below represents the reaction of one molecule of a hydrocarbon with two molecules of oxygen. chemical equation: ch4 + 2o2 → co2 + 2h2o + 1.48 × 10−18 jthe nuclear equation below represents one of the many possible reactions for one fissionable nucleus. in this equation, x represents a missing product. nuclear equation: write an isotopic notation for the missing product represented by x in the nuclear equation.

As we move from left to right across the periodic table, what is the general trend? a) atomic radii increase. b) electronegavitiy decreases. c) nuclear shielding increases. d) metallic character decreases.
