Why does richard rhodes think nuclear power is important moving forward?

Determine the number o moles of ions/atoms/particle in the following: 2.50 miles of k2s (let me know how to do)

Ionic solids such as sodium chloride are easily shattered, but metallic solids such as copper can be easily bent and shaped. this difference occurs because a. ionic solids have low melting points b. covalent bonding between sodium and chlorine keeps the solid rigid c. mobile electrons in the copper can shift without disrupting the solid

Consider a situation in which 161 g of p4 are exposed to 176 g of o2. a.)what is the maximum amount of p2o5 that can theoretically be made from 161 g of p4 and excess oxygen? (i got 2.60 mol) b.)what is the maximum amount of p2o5 that can theoretically be made from 176 g of o2 and excess phosphorus? (i got 2.20 mol) c.)now, determine how many moles of p2o5 are produced from the given amounts of phosphorus and oxygen. (i got 2.20mol/ theoretical yield) is what i need d.)what is the percent yield if the actual yield from this reaction is 206g?
