The atomic masses of the two stable isotopes of boron; boron-10 (natural abundance: 19.78%) and boron-11 (natural abundance: 80.22%) are 10.0129 amu and 11.0093 amu, respectively.  calculate the average atomic mass of boron   10.41 amu 10.95 amu 10.81 amu  10.72 amu  10.13 amu

If you want to create an electrical current, which situation would produce a solution capable of this

Plz choose one of the compounds from the table and explain how you know the numbers of atoms in your formula. is it possible for two different compounds to be made from the exact same two elements? why or why not? with a limited number of elements (less than 120 are known), does this mean we also have a small number of compounds or do we have a large number of compounds in this world?

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.
