Explain why an atom does not have a charge.

Determine the percent sulfuric acid by mass of a 1.61 m aqueous solution of h2so4. %

Americium-241 undergoes fission to produce three neutrons per fission event. if a neutron-absorbing material is mixed in with this sample so that the rate of neutron production drops down to 1.8 neutrons per fission event, which will be effective at achieving a critical mass? check all that apply. remove a deflective shield surrounding the sample. remove absorbent material mixed in with the sample. compress the sample of americium-241.

The chemical bond connecting one nucleotide with the next one along the nucleic acid chain is called a
