We diffusion bond two blocks of Cu and Ni. The wider the interdiffusion zone the stronger is the bonded component. When the process is conducted at 800 o C, the width of the interdiffusion zone is 102 mm, after 3 h. What would be the width, if the process were carried out at 900 o C and lasted for 5 h

Which statement justifies that hydrogen peroxide (h2o2) is a polar molecule? the o – h bond is nonpolar and the molecule is asymmetric. the o – h bond is nonpolar and the molecule is symmetric. the o – h bond is polar and the molecule is asymmetric. the o – h bond is polar and the molecule is symmetric.
