Consider the following unbalanced equation: С2Н4 + O2 CO2 + H₂O How many moles of carbon dioxide will be produced when 5.0 moles of oxygen react? ​

Suppose a diode consists of a cylindrical cathode with a radius of 6.200×10^−2 cm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cm . the potential difference between the anode and cathode is 260 v . an electron leaves the surface of the cathode with zero initial speed (v initial=0). find its speed vfinal when it strikes the anode.
