occurs when an unknown white powder is heated? #1: Sodium bicarbonate breaks down into sodium hydroxide and carbon dioxide. #2: Heating sodium bicarbonate produces sodium carbonate, carbon dioxide and water vapor. #3: Sodium bicarbonate decomposes into sodium oxide, carbon dioxide, and water vapor. Materials: Crucible and Lid Crucible tongs Ring Stand Bunsen Burner Pipestem Triangle Wire gauze Ring Clamp 5.68 grams of Sodium Bicarbonate Scoopula Spatula Scale Procedure: First record the mass of…

Chlorine has a normal phase of gas at 32F, and it also has a vapor pressure at 32F.…

Freezing point is the temperature for a particular compound where the liquid freezes to form a solid (Chemistry Dictionary). If salt is added to water, it freezes at lower temperatures. If there are fewer water molecules, then freezing occurs at a slower rate (Salt and the Freezing Point of Water). Pure water freezes at 0º Celsius, but water that is combined with salt will freeze at a temperature less than 0º Celsius (Oleson, Andrew and Daly, Terik). A solvent is something in which other things…

of atmosphere, the air temperature is 32 degrees Fahrenheit or less, the water vapor switches from gas to solid, creating frozen water called ice crystals. The ice crystals are created from the dust and dirt and make them into hexagonal shapes. Absolutely no snowflake is like the others. They are all unique and different from the others. Snowflakes have a fabulous way of being…

All storms are different from each other and amazing in their own ways. Any storm can destroy a lot of stuff, but it can do so in many peculiar ways. Even though there are many different storms and they are all formed in various ways, different storms can have the same effects, while other storms have diverse outcomes. Some storms that we see often we consider common storms. Although we consider them common, they are still very interesting with assorted parts to the storm. Thunderstorms can be…

centuries. Smoking is inhaling and exhaling the fumes from burning tobacco in cigarettes and other products that use tobacco. Vaporizing, also commonly known as “vaping”, is inhaling and exhaling a liquid that is heated, that then emits the flavored vapor. Over the years, smoking cigarettes has become a “bad habit”, causing health problems that are short term and long term. Due to vaping being new to the mainstream, there are questions and concerns to whether or not vaping is truly better than…

a)The five most important biogeochemical cycles are the oxygen cycle, nitrogen cycle, carbon cycle, sulphur cycle and the sedentary cycle. These five cycles can be classified into pools. Active pools are free flowing cycles controlled by life processes such as photosynthesis. Storage pools are segregated bodies controlled by physical processes such as, volcanic eruptions or earthquakes. Oxygen cycles through the environment in three major forms; gaseous atomic oxygen, and the…

Startling Physics Of The Universal Solvent... " There isn't anything softer and weaker than water, and nonetheless there isn't anything better for assaulting arduous and rugged things." We are all cognizant of the fact that 65% of our bodies and 75% of earth is composed of water and also are familiar to some of its properties yet it stands out to be intensely mysterious. Several of its properties are so strange that even to this day they elude scientific apprehension. • Mpemba Effect: A…

example of physical change, the heat source caused the surrounding wax to melt and drip down the sides of the candle, which then re-hardened after exposure to the air. The flame, is a chemical reaction, which burns wax vapor, which combines with oxygen to produce carbon dioxide and water vapor. Without…
