Key Questions Lesson 1 1. One argument against continuing research on the atom is that the cost continues to increase at an alarming rate‚ and the benefits seem to be declining. Whereas quantum chemistry experiments as early as 80 years ago were very cheap and yielded considerable practical results‚ now very few if any practical results are emerging‚ but the costs of experiments continues to increase. On the other hand a common argument for the continued

CHEM 301 LECTURE Unit 1 0 . COORDINATION CHEMISTRY Factors t hat affect solubility: Common ion: decrease in solubility Complex ion: increase in solubility How does complex ion formation increase solubility? Consider the complex ion formation between silver and ammonia: + Ag + 2NH3 A g(NH3 )2 + Kf = 1 .5 x 10 7 where Kf i s the formation constant (always >1 ‚ formation of the complex is highly favorable) Complex ion formation increases the solubility of sol ids in water

Fusion as a future energy source Creating Nuclear Fusion could be a break through in finding an alternative source of energy. As of today we do not have the technology to make a nuclear fusion reactor‚ but we could be relying on them for power sometime in the next 30 to 40 years. Nuclear Fusion is created by forcing deuterium (D) and tritium (T) together‚ when forced together their nuclei fuse and then break apart to form a helium nucleus and an uncharged neutron. Most of the excess energy

Nuclear Waste by Richard A. Muller Nuclear waste is a radioactive waste that is dangerous‚ and a fair percentage of people would agree on this topic. However‚ is it really dangerous or is it just harmful to an extent? In society‚ many debates are held over trying to prove to the world that this substance is harmful. In the essay‚ “Nuclear Waste‚” Muller states clearly that he sides with the anti-nuke of the debate and how he pinpoints the facts of nuclear waste with great persuasion. Yet‚ it is

Extraction of Aluminium Aluminium ore is called bauxite. Bauxite contains aluminium oxide‚ water‚ iron oxide and other impurities. The purified dry ore‚ called alumina‚ is aluminium oxide (Al2O3). The alumina must be molten for electrolysis to work‚ since the ions are not free to move in the solid state. Unfortunately‚ alumina has a high melting point (2040 °C) and it is not practical to do electrolysis at such a high temperature. In the middle of the nineteenth century it was found that alumina

When Bad Things Happen to Good People When someone does something good‚ great‚ amazing; however it is said‚ a reward is expected. That’s just the way the human brain has been trained in many cultures. People think just that with every good deed that is done. Movies have taught us that the “bad guy” never wins and that a hero will always triumph in the end. Not so much in the real world. Religious views‚ daily decisions‚ and just pure coincidence‚ if you will‚ all influence the outcome of a good

Why good people do bad things? “Doing bad is easy but doing well is not”. Yes‚ that saying is the most concrete explanation why good people do bad things. Good people do bad things with good intentions. We‚ humans‚ are all sinful by nature. No one of us can behave perfectly and sinless. But we have the capacity to avoid temptations and to distinguish what’s right from wrong. Good intentions cause most of the world’s great evils. There are many things that happened in the past that can construe
