A balloon is floating around outside your window. The temperature outside is 1\, ^{\circ}C , and the air pressure is 0.700atm . Your neighbor, who released the balloon, tells you that he filled it with 3.20moles of gas. What is the volume of gas i..
What is the energy per photon of the lowest frequency of electromagnetic radiation that can be used to observe a gold atom with a diameter of 280 picometers.
Treatment of a 0.4g sample of impure KCl with an excess of silver nitrate resulted in the formation of 0.7332g AgCl. Compute the percentage of KCl in the sample.
ond weighs 44.0 carats. Determine the volume occupied by the diamond, given that its density is 3.5 g/cm3 at 20°C, and that 1 carat = 0.200 g.
The thermite reaction in which aluminum metal reacts with iron(III) oxide to produce a spectacular display of sparks, is therefore exothermic that the product (iron) is in the molten state
methane ch4 has a tetrahedral structure similar to that of si02 with a carbon atom of radius 0.77x10-8 cm at the center
What is the potential theoretical oxygen demand (mg O2/L) associated with nitrogen species in the wastewater. My teacher said there should be a way to relate all of these together to find the answer
A sample of calcium metal is contaminated by a certain amount of highly toxic, radioactive thorium metal (Th). A 10.00-gram sample of this mixture is dissolved in acid, and reacted with excess sodium oxalate to form a precipitate which is a mixtur..
The standard enthalpies of formation of ions in aqueous solutions are acquired by arbitrarily assigning a value of zero to H+ ions that is, Hf [H+ (aq)] = 0. For the subsequent reaction- HCl (g) --H20---> H+ (aq) + Cl- (aq) Hf = -74.9 kJ/mol
