What is Ethics? Every human needs some sort of guidance on how to live‚ what to avoid‚ what to seek‚ how to get it. We need that guidance not only in isolated cases‚ but in the most fundamental questions in our lives: What kind of person do I want to be? What lifestyle do I want?

In this experiment‚ 5.281g of trans isomers of [Co(en)2Cl2]Cl was synthesized from 12.249g of CoCl2▪6H2O. First‚ CoCl2▪6H2O was reacted with ethlenediamine (NH2CH2CH2NH2) that formed [Co(en)2(H2O)2]Cl. Then the [Co(en)2(H2O)2]Cl was reacted with H2O2 to change the cobalt’s charge to cobalt(III) from cobalt(II). Finally HCl was added into the solution to form [Co(en)2Cl2]Cl. The percent yield was 45.51%.To synthesis trans isomers of [Co(en)2Cl2]Cl‚ distilled water was first mixed with CoCl2▪6H2O‚

1. Define gravity An attracting force that acts between any 2 objects. 2. What is the difference between mass and weight? Weight is the measure of the gravitational attraction of an object‚ while mass is the amount of matter in an object‚ the measure of an object’s resistance to motion. 3. How does mass affect the motion of an object? The greater the mass‚ the harder it is to speed up or slow down an object. 4. What finding(s) did Galileo uncover regarding falling objects? He conducted an experiment
