A 2000 kg truck experiences a net force of 3900 N starting from rest. After 100 meters, what is the car's velocity?
consider the three flasks in the diagram below. assume the temperature is held constant. when the stopcocks are closed
Commercial hydrogen peroxide contains small amounts of organic compounds which are added to stabilize the hydrogen peroxide. If these compounds react with permanganate, how will this affect your results
At a particular temperature the equilibrium constant for the reaction: H2(g) + F2(g) ? 2HF(g) is K = 36.0. A reaction mixture in a 10.00-L flask contains 0.42 moles each of hydrogen and fluorine gases plus 0.15 moles of HF.
Calcultate what is the value of enthalpy H reaction If the temperature increased from 35.0 degree celsius to 76 degree celsius and the heat capacity of the calorimeter = 23.3kj/c ? (the molar mass of C2H5OH = 46.07g/mol. )
Putrescine [NH2(CH2)4NH2], found in rotting animal tissue, is now known to be in all cells and essential for normal and abnormal (cancerous) growth. It also plays a key role in the formation of GABA, a neurotransmitter.
Draw the three dimensional structure of both the endo and exo adduct formed from 1,3-cyclopentadiene and maleic anhydride.
Pour the water into a 24.0 gram beaker and boil off all the water, so only the salt remains. The beaker with salt in it weighs 41.0 grams. What is the % of salt and % of water
Calculate the solubility of Ce(IO3)3 (pKsp=10.86) in: a) distilled H20 b) 0.300 M Ce(NO3)3 solutiom c) 0.200 M KIO3 solution
A battery charger use to recharge NiMH batteries can deliver as much as 0.40 A of current to each battery. If it takes 100 min to recharge one battery, how much Ni(OH)2 (in grams) is oxidized to Ni(OH)?
For the reaction shown, find the limiting reactant for each of the following initial amounts of reactants. 2Na(s)+Br2(g)->2NaBr(s) 1. 2mol Na, 2mol Br2 Express your answer as a chemical formula.
Assuming that the calorimeter absorbs only a negligible quantity of heat and that the density of the final solution is 1.0 g/mL, calculate the enthalpy change per mole of BaSO4 formed.
The maximum level that the EPA considers safe for lead air pollution is 1.5 µg / m3 . If your lungs were filled with air containing this level of lead, how many lead atoms would be in your lungs? (Assume a total lung volume of 5.50 L.)
