How much LiOH (in grams) is needed to prepare 475 mL of solution with a pH of 11.2 ?
Problem: Bapco needs to burn natural-gas fuel that contains 75 mol% methane, 15 mol% ethane, and 10 mol% nitrogen. The following two reactions takes place: CH4(g) 20209) CO2(0) 2H2o) C2H6 (g) + 3.502(g) 2C02(g)3H20 (g) a) What is the standard heat of combustion (kJ/mol) of the fuel at 25 oC with water(g) as a product b) The fuel is supplied to a furnace with 60% excess air, both entering at 250C. The products leave at 600°C. If the combustion is...
A natural gas power plant uses 505Mg of natural gas per day (volume converted to weight via density ). The energy value of the natural gas is 37.3 MJ/kg. The plant produces 1.81 *10^6kWh of electricity each day a.) what is the efficiency of the plant b.) how much energy is lost please include all base equations engineering principles and general formulas and use. c.) assuming all energy is converted to heat how much water is needed to absorb the...
How much KCL will dissolve in 150 grams of water at 75 degrees celcuis?
(e) The energycontent of natural gas is about 39 MJ/m3 (where 1 MJ = 106) Suppose you need to produce 5.0 x 103J of energy. How much volume (in m3) of natural gas do you need? (f) Sea water has a typical salinity of 39 g/L in dissolved salts. Suppose you have 125.0 mL of sea water. How many grams of dissolved salts can you recover? (g) The atmospheric pressure at the surface of planet Mars is 7.5 mbar (as...
How much work is done on the gas in the process shown in the figure?
It requires 0.86 aJ to ionize a single gas phase Li atom. How much energy is required to ionize 6.022 × 10^23 gas phase Li atoms?
When 10.0 g of hydrogen gas reacts with 40.0 g of nitrogen gas, how much ammonia gas forms? Which substance is the limiting reactant? If a chemist runs the reaction knowing they should obtain a percent yield of 78.5% and must produce a total of 30.5 grams of ammonia, how many grams of nitrogen should they start with if they have an excess amount of hydrogen?
7. Given: Natural gas (CH4) must have the hydrogen sulfide (H2S) removed before it is burned. One way to do this is to pass the natural gas through a bed of zinc oxide (ZnO) (molecular weight of 81, density of 1.11 g/cm3), where following reaction takes place. Outflow ZnO + H2S ? ZnS + H2O You have 1 million standard cubic feet of natural gas per day at 492R and 1 atm with 0.82 mol% H2S. You need to design...
If you could solve all three problems, that would be great! Thanks so much! 1. How much methane (in grams) is produced per mole of synthetic leather (Arginine, C6Hi4N O2)? 4a-b-2c+3d 4a+b-2c-3d 4a-b+2c+3d a) 88.0 grams b) 104.0 grams c) 192.0 grams d) 64.0 grams 2. A gas mixture at 25°C and 1 atm contains 100 mg/L of H2S (MW H2S 34 g/mol). The partial pressure (atm) exerted by the H2S is most nearly: a) 0.0029 b) 0.0056 c) 0.072...
