Pd-100 has a half-life of 3.6 days. If one had 750 grams at the start, how many grams would be present after 18 days?

Ineed with my science work! it’s due tomorrow!

The drawing represents the movement of particles in a substance. what changes of state can this substance undergo

In a spacecraft, the following reaction occurs: co2(g) + 2lioh(s) -> lico3(s) + h2o(i) (i attached picture of equation) how many liters of carbon dioxide will 4 moles of lithium hydroxide (lioh) absorb? (one mole of any gads occupies 22.4 l under certain conditions of temperature and pressure. assume those conditions for this equation.) 45l 6.0l 3.0l 34l
