EXPERIMENT: 1 Object: To find the wavelength of Sodium light by Newton’s ring. Apparatus required: A Plano convex lens of large radius of curvature‚ optical arrangement for Newton’s rings‚ plane glass plate; sodium lamp and traveling microscope. Formula used: The wavelength of light is given by the formula λ =D n2+p –Dn2 / 4pR Where D n+p = diameter of (n+p)th ring Dn = diameter of n th ring‚ P = an integer number‚ R = radius of curvature of the curved face of the Plano- convex lens.

Hydrogen Fuel Cell Cars: Worth the Investment? Hydrogen is the most abundant element in the universe‚ but only recently have people been able to harness this resource and turn it into energy. Hydrogen fuel cell cars are one such advancement made in the effort to turn hydrogen gas into electricity. Fuel cells in the car are used to convert hydrogen into an electrical current‚ and thus power the vehicle. Fuel cells convert hydrogen and oxygen into water while producing electricity. Hydrogen fuel

Discuss why hydrogen bonding is essential for life Throughout biochemistry there are many bonds without which life as it is on earth today would not be possible. One of the most important bonds of these is the hydrogen bond‚ a weak chemical bond that is present in essential biological molecules such as water and polypeptides. A hydrogen bond is defined by Campbell and Reece as occurring when a hydrogen atom is covalently bonded to an electronegative atom but attracted to another electronegative

Yoshida et al.‚ Flexibility of Hydrogen Bond and Lowering of Symmetry in Proton Conductor‚ Symmetry 2012‚ 4‚ 507-516. Paragraph 1 In this paper‚ we take a look at the different phases of the Cs3H(SeO4)2 polymorphs. There are 3 different phases that is observed and each of them is influenced by the temperatures. In addition‚ in each phase‚ the polymorph exhibits different crystal structure. At the room temperature of 298K‚ it will be in phase 3 whereby it takes the structure of monoclinic-C2/m

of 0.1M Sodium phosphate Monobasic‚ which equal 2.9995g‚ we added it to the 250ml beaker and added 50.0ml of water to dissolve it. On the same time‚ we prepared 250ml of 0.1 Sodium phosphate Dibasic‚ which equal to 3.549g; we added 50.0ml of water to be dissolved. We made these two solutions in order to get their PH. We started with PH 6.0 buffer from Sodium phosphate monobasic solution‚ we added 50ml of Sodium phosphate Dibasic to 250ml beaker‚ placed PH probe‚ then added solution Sodium phosphate
