A. Any man thinks he has any right to even have a say in the matter. Do you go through pregnancy and childbirth? Do you even understand what a toll that takes on a woman’s body? No? Okay then. B. People always suggest "alternatives" to abortion. I was adopted and I am all for it‚ but until you have placed a baby for adoption and know first hand how terribly difficult that is‚ don’t suggest it‚ like it’s some easy solution to a very difficult situation. C. Think about this‚ what if someday you

during which I developed an acumen towards chemistry and chemical science. The orientation before practical session increases my eagerness about chemistry to the zenith of my learning. At that moment I decided to pursue my career in chemistry and grab every opportunity where I can enhance my learning of the subject and deepen my conceptual knowledge of the subject. The sole reason for this alacrity‚ I would attribute to my undergraduate Professor Dr. S. Vanmali. His approach to teaching subject considering

Lab 1 “Laboratory Techniques and Measurements” A. Water boils at 100C at sea level. If the water in this experiment did not boil at 100 C‚ what could be the reason? * We’re not at sea level; the pressure could be lower or higher. B. While heating two different samples of water at sea level‚ one boils at 102C and one boils at 99.2C. Calculate the percent error for each sample from the theoretical 100C. (show your work) * 1st Sample: 1.96% error * 2nd Sample: 0.81% error

Laboratory Measurements and Density Objectives: A. To determine the density of Aluminum (lit. value = 2.7 g/cm3) by determining its mass‚ and measuring its volume by dimensional analysis and water displacement. We will also examine the % error in our determination based on the literature value. B. To determine the mass and diameter of select ball bearing. Plot graphs of mass vs. diameter‚ mass vs. surface area‚ and mass vs. volume. Afterwards use slop of the mass vs. volume graph to determine density

Importance of Chemistry Chemistry is an important branch of science. Chemistry deals with the matter that form our environment and the transformation that the matter undergoes. Chemistry is therefore‚ useful in understanding the changes taking place in the constituents of the environment and the resulting advantages. Chemistry is connected with composition‚ structure and properties of the matter. In fact it is a science of atoms and molecules. Organic chemistry‚ inorganic chemistry‚ physical chemistry‚ analytical
