An imperial cruiser fires its lasers at the rebel frigate 12X10^30 photons of 505nm wavelength slam into the frigate. The frigate was mostly constructed from high quality materials such as duranium a highly heat resistant material mostly made of tungsten hat has the following properties:
Specific heat solid: .13 J/(gK)heat of fusion: 35.40 kJ/MolSpecific heat liquid: .30 J/(gK)heat of vaporization: 824 kJ/MolMelting point: 3422 C boiling point: 5550 CAtomic weight :as for tungsten (W)h=6.26x10^-34 Js c=3.00x10^8 m/s
What is the maximum amount of hull plating of the frigate that can be vaporized by the incoming blast? Assume that frigate is at a nice climate controlled 20 C
4 KO2 + 2 H2O + 4 CO2 ==> 4 KHCO3 + 3 O2 How many moles of O2 will be produced if 5.17 moles of CO2 react completely?
If the water in a well has 1000.0 mg/L of CaCO3 dissolved in it, How many grams of Na2C2O4 could you mix with 100.0 mL of that water before a precipitate would form
How many grams of dry NH4Cl need to be added to 2.30 L of a 0.100 M solution of ammonia,NH3, to prepare a buffer solution that has a pH of 9.00
what products would expect to obtain in the reaction of alpha-naphthaldehyde with KOH? write a detailed reaction mechanism.
Methanol is toxic for humans if they ingest liquid methanol or inhale methanol vapor in significant quantities. When inhaled in concentration greater than 1000 ppm, death has been reported.
A metal sulfide, M2(CO3)3, has a Ksp of 8.75 x 10^-42. What is the molar solubility of this sulfide in water. Assume the sulfide dissolves ideally (ignore hydrolysis effects).
Calculate the molar enthalpy change ?H~rxn for the dissolution of KNO3 in water. Calculate in the error in ?H~
Bioremediation is the process by which bacteria repair their environment in response, for example, to an oil spill. The efficiency of bacteria for "eating" hydrocarbons depends on the amount of oxygen in the system
what is the boiling point of cyclohexane at 600
A cell based on the reaction below has a standard potential of +0.42 V at 25°C. If all of the species are at standard conditions except [H+], at what pH will the cell have a potential of zero
What is the heat capacity of a bomb calorimeter if the combustion of 2.757 mmol of salicylic acid (C7H6O3(s), Hcomb = -3022 kJ/mol) increases the temperature of the calorimeter by 2.612°C
