Chromium-51 is used in imaging red blood cells and has an effective half-life of 27 days. If a dose with an activity of 24 μCi is given to a patient, how long will it take for the patient to have less than 3 μCi present?
Express your answer as an integer.

Hno3(aq) → h+(aq) + no3−(aq). picture ii best represents the strong acid hno3. strong acids are strong electrolytes

Aconductor easily transfer heat

Firstly, the water in the dams hold gravitational potential energy as they are above ground level. the gravitational potential energy is then transferred to kinetic energy as it falls, spinning the turbinethe turbine then spins the generator, which is a large magnet surrounded by metal coils. by doing this, the generator generates electricity. in this action, the energy transfer taken place is kinetic to electric energy
