When c-14 transmutates into n-14, this represents 14 6 carbon becomes 14 7 nitrogen plus blank an alpha decay electron capture negative beta decay gamma decay?

Which substances have the lowest melting points: ionic covalent, or metallic

Ineed to find the answer of this question because i dont understand it

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins.co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)
