Answer:

34,690 g O₂ used.

Explanation:

Balance Equation

              12B₂H             +                      21O₂                           => 12B₂O₃ + 6H₂O

Given 14,000g B₂H          moles O₂ consumed to burn 619.47 mol B₂H

=(14,000g/22.6g/mol)        = 21/12 x 619.47 mole O₂ = 1084 mole O₂

= 619.47 mol B₂H used        1084 mol O₂ x 32 g/mol = 34,690 g O₂ used.

Which statement is part of Bohr's atomic model?
kolbaska11 [484]

The answer is A According to Bohr’s model, when an electron absorbs energy of a specific wavelength, it is able to jump to a higher orbital level. Conversely, when the electron jumps to a lower orbital level, a photon of energy of a specific wavelength is emitted. This process is unique for every atom with regards to the specificity of the photons it absorbs and emits. This property of atoms is what is harnessed by spectrometers to determine the types of an atom in a substance.
