Use the balance to determine the mass of the rectangular solid. Record the mass to the nearest 0.01 g in the data table. Volume: Use the metric ruler to measure the length‚ width‚ and height of the rectangular solid. Record these measurements to the nearest 0.1 cm in the data table. Calculate the volume using the following formula: Volume (cm3) = length (cm) x width (cm) x height (cm)

Alex N EIV AP p.1 The worst kind of fear is the fear of the unknown. The fear of not knowing. When you turn around‚ but there is nothing there. When you feel like you are being watched‚ but there’s nothing there. When you hear your name called out‚ but you are alone. That is the essence of fear. There are creatures‚ monsters‚ that feed off this fear. They incite doubt to feed‚ worry to drink‚ and fear to grow. Monsters live off of fear‚ like a parasite feeding‚ it eats and eats taking away hope

Lesson 3.01: History of the Periodic Table 1. Explain how scientific observations led to the development of‚ and changes to‚ the periodic table. Dmitri Mendeleev- first periodic table‚ organized 63 known elements according to properties‚ organized into rows and columns. He wrote names‚ mass and chemical properties on each. Julius lothar Meyer- independently worked in German ‚ similar to Mendeleev Henry Gwyn Jeffrey’s Moseley: worked with Ernest Rutherford experimented with 38 metals‚ he found that

DEVELOPMENT OF THE PERIODIC TABLE Although Dmitri Mendeleev is often considered the "father" of the periodic table‚ the work of many scientists contributed to its present form. Elements such as gold‚ silver‚ tin‚ copper‚ lead and mercury have been known since earliest times. In 1649 the first scientific discovery of an element occurred. Hennig Brand‚ a German chemist‚ treated urine to a series of processes that resulted in the production of the element phosphorus. Over the next 200 years

Two conditions for equilibrium are that the net force acting on the object is zero‚ and the net torque acting on the object is zero. In the experiment done‚ conditions for equilibrium are observed. Equilibrant forces were determined using the force table and component methods. The unknown forces were also determined using the first and second conditions for equilibrium. Another part of the experiment was to locate the center of gravity of a composite body and to determine rotational equilibrium.

China is a country with 5000-years-long civilization and a long and rich history‚ so Chinese like to pay more attention to the etiquette‚ especially in the table manners. Most foreigners do not know table manners when they join in Chinese dinner party because Western dining is different with Chinese. Chinese table manners have three important parts‚ including place setting‚ taboos‚ and toast. Firstly‚ the seating arrangement is one of the important parts of dinning etiquette because the order of

Promethium‚ Pm‚ is the 61st element on the Periodic Table. It was discovered in 1945 by Jacob A. Marinsky. It’s a metal‚ and named after the Greek God Prometheus. It is not naturally occurring‚ but can survive outside of a lab. Promethium has an atomic number of 61‚ which is the number of protons. Its atomic mass‚ protons+neutrons‚ is 145u. It is an isotope. This means that it has a different number of neutrons (84) than the number of electrons and protons (61). Every element changes states

in the d-block and it is a transition metal. Technetium is in the 7th group in the periodic table because it has 1 electron on its last shell. Also it is in the 5th period in the periodic table because it has 5 shells. Number of energy levels of Technetium is 5. Its electron shells are 2‚8‚18‚14‚1 as it is in the picture. Firstly‚ Russian chemist Dmitri Mendeleev‚ who is the creator of the periodic table‚ predicted Technetium’s existence. He called it eka-manganese because there was a missing element
