The economics of the world heavily correlates to the pattern of colonization that swept across the globe in the 1700’s. In the eyes of colonizers‚ their duties were strictly to enlighten the people of these univillied nations while retrieving goods to take back to their people. Going to places like Africa and Asia‚ natural resources were abundant‚ so colonizers felt as if taking these goods were not a disservice

APWH Unit 4 COT essay: Commerce in the Indian Ocean In the Indian Ocean region from 650 C.E. to 1750 C.E.‚ commerce changed in that there was a shift in dominance over trade‚ and the demand of certain products changes‚ and a continuity was the Europeans’ demands for goods from Asia. A change in commerce from 650 C.E. to 1750 C.E. was the changing of control over trade. Around 650 C.E.‚ the Swahili dominated the trade‚ especially since there were so many coastal forts of the east side of Africa

Lab 4 Projectile Motion Sai Moua Purpose: The purpose of this lab was to define what the initial velocity of the ball when it is launched out of the pipe. Our next objective is to determine at what angle that the ball will be ejected at the maximum range. Lastly‚ we predict and confirm the range before we launch the ball at a certain angle. Theory: Projectile motion according to Dr. James S. Walker is defined as‚ “the motion of objects that are initially launched –or “projected”- and that

Introduction: The purpose of this lab will be to investigate the concepts of accuracy and precision for quantitative measurements using density as an example. The density of a sample will be found experimentally and compared to a known value. The relationship of averages and different analysis techniques to percent error will also be explored. Density is a characteristic of a substance which can qualitatively be described as the amount of matter (mass) squeezed into a given space (volume). The

That is‚ the entering group does not for the most part have the same position on the ring as that purged by the halogen substituent. Case in point‚ the hydrolysis of 4-chloromethylbenzene at 340° gives an equimolar mix of 3-and 4-methylbenzenols: Significantly all the more striking is the elite development of 3-methoxybenzenamine in the amination of 2-chloromethoxybenzene.

Question 2.1: (i) Calculate the number of electrons which will together weigh one gram. (ii) Calculate the mass and charge of one mole of electrons. * ------------------------------------------------- Answer (i) Mass of one electron = 9.10939 × 10–31 kg Number of electrons that weigh 9.10939 × 10–31 kg = 1 Number of electrons that will weigh 1 g = (1 × 10–3 kg) = 0.1098 × 10–3 + 31 = 0.1098 × 1028 = 1.098 × 1027 (ii) Mass of one electron = 9.10939 × 10–31 kg Mass of one mole of
