The remaining solid is known as the anhydrous salt‚ which is the compound same compound without the water molecules trapped inside. Title:The title of the lab should be at the top of the lab report.

is used in products such as fertilizer‚ and it helps aid in the production of plastics‚ pharmaceuticals‚ and even margarine. Also‚ hydrogen’s low density makes it a natural choice for filling balloons and airships (Robertson 6-10). The molar volume of hydrogen gas is reliant on the number of moles of magnesium combined with excess hydrochloric acid. In simpler terms‚ the excess

determined using the mass of water and dividing it by the total mass of the hydrate and then multiplying that answer by 100%. The number of moles of water in a hydrate was determined by taking the mass of the water released and dividing it by the molar mass of water. The number of moles of water and the number of moles of the hydrate was used to calculate the ratio of moles of water to moles of the sample. This ratio was then used to write the new and balanced equation of the dehydration process

They are usually made of glass or plastic‚ and while most are scored for measurement‚ some can measure changes digitally. The single-tube manometer measures only the pressure of a liquid‚ since there is no alternate place to compare gases. A U-shaped manometer essentially pits two different gas pressures against one another‚ and measures the strength of the captured gas. The free-flowing gas is usually air at the

20 THINGS YOU CAN DO TO CONSERVE ENERGY Whenever you save energy‚ you not only save money‚ you also reduce the demand for such fossil fuels as coal‚ oil‚ and natural gas. Less burning of fossil fuels also means lower emissions of carbon dioxide (CO2)‚ the primary contributor to global warming‚ and other pollutants. You do not have to do without to achieve these savings. There is now an energy efficient alternative for almost every kind of appliance or light fixture. That means that consumers

What needs to be done to achieve greenhouse gas reduction targets by 2020? Since the beginning of Industrial Revolution‚ concentrations of carbon dioxide‚ methane‚ and nitrous oxide have all risen dramatically because of human activities. Fossil fuel combustion‚ land-use change‚ increasingly intensive agriculture‚ and an expanding global human population are the primary causes for these increases. Other greenhouse gases found in our planet’s atmosphere include water vapor and ozone. Carbon
