A graduated cylinder contains 146mL of water. A 15.0g piece of iron (density=7.86g/cm3) and a 24.0g piece of leaf are added. What is the new water level of the cylinder

Why are the trends and exceptions to the trends in ionization energy observed?

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.

Neils bohr believed that electrons orbited the nucleus in different energy levels, based on strong support from
