My latest gas bill illustrate that natural gas costs $1.43 per 100 std ft3, while electricity costs $.19/KWh. Presume that natural gas mostly CH4 produces heat equal to 890.35 KJ/mol when burned is it cheaper to heat with electricity or natural gas? A std ft3 is measured at 60 F and 1 atm
A 0.2527-g sample of a mixture of Mg(OH)2 and Al(OH)3 was treated with 50.00 mL of 0.225 mol L 1 HCl(aq). The resulting solution required 13.73 mL of 0.176 mol L 1 NaOH(aq) to neutralize the excess, unreacted HCl.
A student used the (CH3COOH) solution prepare in question 2 to titrate 25.00mL of 0.1246M of calcium hydroxide solution, what volume of CH3COOH solution was required for the titration
In a solution mixture of a 0.010M weak acid and 0.10M weak base, the measured pH was 4.75 at 24C. calculate the Ka of this weak acid. if 10mL of this mixture was then diluted with distilled water to a total volume of 100mL, what would be the new p..
using structures for all species write the complete esterification reaction begun belowmethanol ch3oh salicyclic acid
If 25.0 ml of .451 M NaOH solution is titrated with .253 M H2SO4, identify the principal components (ions, molecules) in the flask at the endpoint besides solvent water or indicator.
A professional emergency responder should be concerned about the following routes of radiation exposure for a person on scene and a person downtown?
A microwave oven operating at 1.22 x 108 nm is utilized to heat 150 ml of water roughly the volume a tea cup from 20 C to 100 C. Compute the number of photons needed if 92% of microwave energy is converted to the thermal energy of water.
What is the ratio between HCO3- and HCO3H to produce a buffer with a pH of 6.5? Ka of HCO3H is 7.94 x 10-7.
Calculate the total energy (in kJ) absorbed by a person exposed to this radiation for 2.0 hours, given that there are 2.0 x 10^16 photons hitting earth's surface per square centimeter per second and the exposed body area
A certain reaction has an activation energy of 63.62 kJ/mol. At what Kelvin temperature will the reaction proceed 4.50 times faster than it did at 347 K
At 650K MgCO3(s)(----)MgO(s)+CO2(g) has Kp=0.026. A 10L container at 650K has 1.0 g of MgO(s) and CO2 at P=0.0260 atm. The containeer is than compressed to a volume of 0.100L. Find the mass of MgCO3 that is formed
Consider a house into which radon is emitted through cracks in the basement. The total volume of the house is 650 m3 (assume that the volume is well mixed throughout).
