Calculate the amount of energy released in the formation of one mole of base bonds (not lattice energy). the radius of the barium ion is 1.35 å, and the radius of the selenide ion is 1.98 å. note that 1å=10−10m.

Asample of radium-226 will decay 1/4 of its original amount after 3200years. what is the half-life of radium-226?

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

What reaction is taking place? 02 + c3h8 = h20 + co2
