There will have some error. 2) A volatile liquid was allowed to evaporate in a 43.298 g flask that has a total volume of 252 ml. the temperature of the water bath was 100˚C at the atmospheric pressure of 776 torr. The mass of the flask and condensed vapor was 44.173 g. calculate the molar mass of the liquid. T = 273 + 100 = 373 V = 252 mL = 1 L / 1000 mL = 0.252 L P = 776 Torr R= 0.0821 mass of 44.173 - 43.298 g = 0.875g moles of gas = PV / RT = 776 x .252 / 62.363 x (273+100) =0.00841 moles molar mass = 0.875g / 0.00841 moles = 104.1 g/
If the temperature was less than the water bath in some places because only part of the pipet was immersed in the boiling water, the molar mass calculated would become lower. This is because the ideal gas law temperature value would be too low, therefore lowering the overall
It is very corrosive and causes severe burns. It is very harmful by skin contact or by inhalation of dust. This cocktail together is used for getting into the ground and then it contributes to global climate change creating air pollution. They argue that fracking harms the environment and can hurt other living species such as bird, and fish. All of this is true; however, natural gas is a cleaner burning fuel and it has other advantages.
hoSpecific heat capacity in liquids Specific heat capacity in liquids How do liquid filled radiators work and what are the useful properties of these liquids? Liquid-filled electric radiators are sealed units that have an internal heating element that releases heat through the outer case; however the elements are put in a liquid such as: oil, water or heat transfer agent. Depending on the design of the radiator, the heat generated can be through radiation or a combination of radiation and convection (1). (10) (10) The liquid used is anti-freeze which is made up of ethylene and propylene glycol (13). Ethylene glycol is mixed with water so it is 50% of each liquid in the solution and has the highest boiling point than any other radiator fluid (5); its boiling point is 197.3°C and has a melting point of -12.9°C (12).
high melting point, hard, brittle, slightly soluble in water, conductor of electricity when melted or in solution Molecular solid - crystalline solid that has molecules arranged in a particular configuration. low melting point, generally insoluble in water, nonconductor of electricity. Metallic solid - crystalline solid that has atoms of metals arranged in a definite pattern. low to high melting point, malleable, ductile, conductor of electricity, insoluble in most solvents. Lesson 13.6 Changes of physical state: * necessary to draw a temperature-energy graph to see the change in temperature with a constant application of heat Heat of fusion - the amount of heat required to melt 1.00 g of substance.
It keeps you warm, it is perfect for outwear and keeps your body heat. Without proper fleece made from polyester, you can lose a lot of body heat and you will feel cold and unprotected. It is light on weight and you can put a spare in your rucksack. Base layer (thermals) – the base layer could be a t-shirt or a long sleeve shirt. It dries quickly, it is very light on weight, you can actually squeeze it, if it is wet and it will dry immediately.
As the number of moles decreases, the volume decreases Summary: Combined Gas Law: PV/nT = constant (T in Kelvins) P1V1/n1T1 = P2V2/n2T2 Ideal gas Law: PV = nRT R = .0821L atm/mol K Gay-Lussac’s/Avogadro’s Law of Combining Volumes Equal volumes of any gases at the same temperature and pressure contain the same number of moles of gas. The coefficients of a balanced equation can be used to calculate relative volumes. Standard Molar Volume: At standard temperature and pressure (STP = 1atm and 273.15K) 1 mole of any ideal gas has a volume of 22.4L Variations on the ideal gas law equation: PV = mRT/M (m = sample mass, M = molar mass of the gas) d = MP/RT (d = density of the gas in g/L) Examples: 1. Calculate: a. The new pressure in a closed container if a 5.0L volume of gas at 2.5atm has its volume increased to 7.5L.
The heat from the steam decreases the viscosity of the heavy crude oil or bitumen which enables it to move down into the lower well chamber. The steam and gases rise because of their low density compared to the heavy crude oil below. The gases released, such as carbon dioxide, methane, and hydrogen sulfide, tend to rise into the steam chamber, filling the void space left by the oil. Oil and water flow countercurrent, gravity driven drainage into the lower well. The condensed water and crude oil is recovered at the surface by pumps such as progressive cavity pumps that work well with high viscosity fluids and suspended
Drugs can be delivered directly under the skin (subcutaneously). It is useful for efficient, slow, and even absorption for sustained effects on the body but drug substance can be irritating. Inhaling drugs can be a great way of administering a drug considering the rapid absorption and avoidance of hepatic first pass metabolism. But there is not really a good way of regulating the dose. Intrathecal drugs is a rare way of administering drug directly into the CNS but there is a higher risk for systemic toxicity.
Overall considering both the pros and cons, I believe fracking should be allowed in my state since the pros outweigh the conds. Overall it’s safer and more dependable than other fossil fuels in my opinion. A sinkhole is a hole in the ground that occurs either with erosion or water drainage. Considering the
