Problem 5. [Einstein's E = mc²] Sun is producing energy by nuclear fusion reactions converting four hydrogen nuclei to form one nucleus of He, i.e. 4H + He. However, mass of helium nucleus is smaller than that of four hydrogens and this difference is called mass defect. If mass of the hydrogen nucleus is my and mass of the helium nucleus Mhe mass defect of one nuclear reaction Am is equal to Am = 4 *my - Me (1) Using...

(Part A) Hydrogen peroxide is unstable and decomposes readily: 2H2O2(aq) → 2H2O(l) + O2(g) This reaction is accelerated by light, heat, or a catalyst. The concentrations of aqueous hydrogen peroxide solutions are normally expressed as percent by mass. In the decomposition of hydrogen peroxide, how many liters of oxygen gas can be produced at STP from 26.8 g of a 7.50% hydrogen peroxide solution? (Part B) What volume of bromine (Br2) vapor measured at 100.°C and 700. mmHg pressure would...

8. Consider how the heavy elements that make up planets like the earth are formed. Which of the following is most likely to be true about the origin of Earth? Earth arose around a very ancient star (our sun) that had had plenty of time to synthesize heavy elements. Earth arose in a region of our galaxy where few earlier stars formed so that the hydrogen fuel for our sun was abundant. Earth arose in a region that was very...
