Acids‚ Bases‚ and pH Lab In this lab the testing of whether or not a substance was an acid or a base occurred. Each substance was tested with the indicators red litmus paper‚ blue litmus paper‚ pH paper‚ phenolthalein‚ bromthymol blue‚ and phenol red. While the substances were tested the group noticed that the substances tested with the red and blue litmus paper‚ the phenolthatein‚ bronthmol blue were the easiest to interpret. The color changes that occurred when this indicator was put into a substance

Ammonia and Hydrochloric Acid Lab Chemistry 1 Abstract The straw should be cut shorter to 8 cm in order to make the solid ring appear in the center of the straw. We achieved our goal‚ cutting the straw caused the gases to not have to go as far‚ and meet in the middle. Background The particles in a gas are very loose and tend to move around a lot very quickly. The particles in a solid are very compact and vibrate but don’t really move very much. The particles in a liquid however are more

I am a member of Kappa Alpha Psi Fraternity Inc. and being apart of this lifetime bond we pride ourselves in service centered on better the institution we attend and the neighboring communities. This semester my brothers and I have participated in multiple community service experiences‚ but what I particularly would like to speak about is a service that I am currently putting together. This service would involve my fraternity brothers and I volunteering time on Saturdays at the New Orleans YLC. What

Acid Rain Air pollution is one of the most common outcomes of the combustion of fossil fuels. A common air pollutant that is released is sulphur dioxide and nitrogen oxides. This is because when coal and fuels obtained from crude oil are burned‚ sulpur and nitrogen is released into the atmosphere‚ which is eventually joint with the oxygen in the air to produce sulfur dioxide and nitrogen oxide. When these gases are emitted in sufficient quantities‚ it reacts with the water and oxygen in the atmosphere

Eric McKenzie Geophysical Science Honors February 14th‚ 2014 ACID RAIN 1. Acid rain is rainfall created by pollution in the atmosphere. When the rainfall occurs‚ it almost always causes harm to the environment. 2. Acid rain is caused by the release of certain compounds into the air‚ including sulfur dioxide and nitrogen oxides. These compounds mix and react with chemicals such as oxygen and water and form acid rain. 3. Acid rain can harm the environment by acidifying lakes and streams‚ which greatly

1. Background & key issues The purpose of this case study is identify key issues causing the failure of introducing new leadership to Alpha Mills‚ providing an analysis and recommendations on how the directors/manager could have prevented these problems. Key facts: Alpha Mills is an oil palm plantation wholly owned subsidiary of a British multinational company located in Malaysia‚ it supplies crude palm oil for its parent company’s detergent manufacturing business. Most of the managers have

What is Acid Rain? First identified in 1872 in Sweden and studied in the U.S. beginning in the 1950s‚ acid rain is precipitation in the form of rain‚ snow‚ hail‚ dew‚ or fog that transports sulfur and nitrogen compounds from the high atmosphere to the ground. Sulfur dioxide (SO2) and nitrogen oxides (NO‚ NO2) are bi-products from burning fuels in electric utilities and from other industrial and natural sources. These chemicals react with water‚ oxygen‚ carbon dioxide‚ and sunlight in the atmosphere
