The pressure inside a pressure cooker is 2.0 atm. how many minutes will it take to cook 1.0 pound of potatoes in a pressure cooker if it takes 45 minutes to cook them in boiling water at standard pressure? given: volume of the pressure cooker is 4.0l, there are 0.25 gaseous moles, and e_a = 1.77 x 10^55 j/mol.

It is 4.92 e-4 sorry if i am wrong

Go ask spider man

Aquantity of that isotope to decay to 1/2 of  its original value

Electron equations of the given changes are as follow,a)                              cu      →      cu⁺²  + 2e⁻b)                              mg⁺²  +  2 e⁻      →      mgc)                              cl⁻    →      cl  +  1e⁻d)                              s  +  2 e⁻    →      s²⁻e)                                o²⁻      →      o  +  2 e⁻f)                              p  +  3 e⁻    →      p³⁻g)                              fe²⁺    →      fe³⁺  + 1 e⁻h)                              s²⁻    →      s⁴⁺  +  6 e⁻
