CHEMISTRY : EXPLORATIONS – THE PROTON-PROTON CHAIN

Document Content and Description Below

In this exploration you will be examining the most common nuclear reaction in star, the Proton- proton chain. This is in the OpenStax textbook on page: 568, 570, 584 See the video of the Animation ... posted on d2l. OR Download the zip file that contains all the ‘Class Action’ animations. After opening, click on the 'Animations' tab on the bottom left. Inside the tab, click on 'Proton-Proton Animation' (in the ‘Sun and Solar Energy’ section). See below Figure 1- screen shot of animation(left); blue arrow shows the sub-section (right) This animation is excellent. Press play, and watch the animation all the way through once. Press play again, and pause the animation after the first collision. Two hydrogen nuclei (both positively charged) have collided to produce a new nucleus with only one positive charge. 1. Which particle carried away the other positive charge? Positron 2. What is a neutrino Did the neutrino enter the reaction or was the neutrino produced in the reaction? [Show More]
