find the mass of 30 cm of the ribbon. 3. Using stoichiometry and the ideal gas law‚ calculate the mass of magnesium metal needed to collect exactly 40 mL of H2 gas from the reaction given. Make sure to use current temperature and local barometric pressure. 4. Calculate the length of magnesium ribbon using the mass you found in step 3. 5. Cut the length needed of magnesium ribbon. 6. Obtain about 25 cm of copper wire

determining the volume of a known amount of gas (H2) at a measured temperature and pressure. Determination of Whether Boyle’s Law Applies to Air Boyle’s Law states that for a fixed amount of gas at constant temperature‚ the pressure of the gas will vary inversely with the volume so that P ∝ 1/V or PV = a constant (if n and T are constant). To determine whether this relationship holds for a mixture of gases‚ the pressure of a fixed amount of air (which is a mixture of gases) will be measured as the

One will find that the NGV really stand out from them all in the sense that it preserve environment and is 50% cheaper With it’s quality as gas and pressure as high as 200 Bar or approximately 3000 Pond per square meter‚ to be compress into the different sizes tank according to the suitability on usage. The safety of the tank containing NGV gas is very important‚ each of the tanks has to be according

the tube. Its height adjusts according to the air pressure on the reservoir. The column of mercury is shorter on a mountaintop as there is less atmosphere to exert a force on the mercury reservoir. On a mountaintop‚ the air pressure is less‚ so the height of mercury it balances in the barometer is shorter than at sea level where there is more air pressure. The pressure of mercury is its weight (force) per unit area. The weight‚ and thus the pressure‚ of the mercury column is directly proportional to

relationship among the complete pressure and capacity of gas‚ if the temperature is reserved in stable within a closed system. The mathematical expression for Boyles Law is: V=K(1/P) or PV=K (Constant T and n) Where‚ P and V are the pressure and volume of the gas sample respectively. K is a constant and dependent of the temperature (T) and the amount of gas (n‚ moles). The Graph below successfully indicates Boyle’s Law visually: A: Volume Verses Pressure B: Volume Verses 1/P Part

September 16‚ 2010 Parental Pressure on Teens In the movie‚ American Teen‚ there were many types of parental pressures shown on teens entering college. This is a negative trait because more often than not‚ this leads the teen in the wrong direction or results in the teen making poor decisions. According to the PewResearchCenter‚ only nine percent of college students think that they need more parental pressure. In life‚ emotional‚ traditional and financial pressure will have a negative impact on
