What percentage of a radioactive species would be found as daughter material after seven half–lives?

What is the oxidation state of each individual carbon atom in c2o42−?

Asubstance is held in an open container. its particles move past one another at random speeds but do not leave the container. heat is removed from the system, and the particles slow down. when enough heat is removed, the particles no longer have enough speed to overcome the weak attractive forces between them. when this happens, the substance enters its solid state. the process described above is known as .

Convert a speed of 201 cm/s to units of inches per minute. also, show the unit analysis by dragging components into the unit‑factor slots.
