Rachael Rice Humanities What Was The Federal Theatre Project????? Throughout the late 1920 ’s an important theatrical movement developed: The Workers ’ Theatre Movement. In the end‚ it diminished around the middle of the 1930 ’s‚ and one of the developments aiding the decline of the Workers ’ Theatre Movement‚ was the creation of the Federal Theatre Project. The Federal Theatre Project was the largest and most motivated effort mounted by the Federal Government to organize and produce

DIFFDiffusion of Chemicals * Diffusion-is the process whereby particles of liquids‚ gases‚ or solids intermingle as the result of their spontaneous movement caused by thermal agitation and in dissolved substances move from a region of higher to one of lower concentration. The rate of diffusion depends on the size of the surface area to the volume in the cell. The higher the surface area of cells in relation to their volume‚ the quicker diffusion takes place. Experiment on Diffusion Aim: to

you thought diamonds were a confusing topic‚ since you have color and clarity to consider‚ you haven’t ventured into the world of diamond simulants‚ yet. There are mined diamonds‚ lab-created diamonds and simulants. The categories can be incredibly confusing‚ so here we’ll focus on simulants and the difference between Asha and Diamond Nexus simulants in particular. What is a Simulant? First‚ you might be wondering what is a simulant. A simulant is a material that looks like diamond but does not

All reactions are able to reach equilibrium but only if they it happens in closed systems. Dynamic equilibrium is a state of balance where forward and reversed reactions happen at the same time. 2. Describe what you observed in each part of this lab. Do you think that each part of this activity helped illustrate the

Chemical reactions involve the making and breaking of bonds. It is essential that we know what bonds are before we can understand any chemical reaction. To understand bonds‚ we will first describe several of their properties. The bond strength tells us how hard it is to break a bond. Bond lengths give us valuable structural information about the positions of the atomic nuclei. Bond dipoles inform us about the electron distribution around the two bonded atoms. From bond dipoles we may derive electronegativity

CHEMICAL WEATHERING Chemical weathering is a process of alteration of rocks of the Earth’s crust. is a chemical decomposition process. is brought out by atmospheric gases and moisture. End product has a different chemical composition and poorer physical constitution. The process: Chemical change in the nature of rock takes place in the presence of moisture containing many active gases such as CO2‚ N2‚ H2‚ and O2. Rocks are made up of minerals.

Chemicals of Life • With the exception of water‚ virtually all chemicals of life are CARBON based • Molecules that contain Carbon are considered organic with some exceptions such as CO2 • Carbon has 4 valence electrons so it is oriented in a tetrahedron shape Sketch→ • Carbon can form up to 4 covalent bonds and can form long chains‚ rings‚ and branched chain molecules • Carbon acts as the backbone of biological molecules • Molecules that only contain carbon and hydrogen are known as hydrocarbons→

Chemical Reactions & Equations CHEMICAL REACTION : In a reaction when the original state of the particle changes and it cannot be reversed by simple physical means‚ this type of reaction is known as chemical reaction. Example :- Fermentation of grapes‚ burning of wood etc. In this reaction we have seen that after burning of wood‚ coal is formed and we cannot make wood from coal. PHYSICAL REACTION : In a reaction when original state of the particle can be recovered by any means then this type of
