State the Law of Conservation of Mass and explain its relationship to stoichiometry. The Law of Conservation of Mass states that “Matter can neither be created nor destroyed during a chemical reaction.” This law is dictates the necessity for balancing a chemical equation with coefficients; if we didn’t balance equations‚ we would be created and/or destroying

Introduction to Gas Turbines A turbine is any kind of spinning device that uses the action of a fluid to produce work. Typical fluids are: air‚ wind‚ water‚ steam and helium. Windmills and hydroelectric dams have used turbine action for decades to turn the core of an electrical generator to produce power for both industrial and residential consumption. Simpler turbines are much older‚ with the first known appearance dating to the time of ancient Greece. In the history of energy conversion‚ however

is * Sulfur mustard is a type of chemical warfare agent. These kinds of agents are called vesicants or blistering agents‚ because they cause blistering of the skin and mucous membranes on contact. * Sulfur mustard is also known as “mustard gas or mustard agent‚” or by the military designations H‚ HD‚ and HT. * Sulfur mustard sometimes smells like garlic‚ onions‚ or mustard and sometimes has no odor. It can be a vapor (the gaseous form of a liquid)‚ an oily-textured liquid‚ or a solid

Oil And Gas: How Both Affect The Economy The economy is affected by many factors that determine if it is strong or weak. These factors have to do with buyers consuming goods and services and at what rate they do this. Do the goods and services that are consumed by people created wealth‚ jobs and a better overall economy for a country. Throughout history some economies have evolved faster and stronger than others.
