When formic acid is heated it decomposes to hydrogen and carbon dioxide in a first order decay calculate the partial pressure of formic acid if the intial pressure at time 0 equal 220 torr
Description of Balanced equations, Identify the steps involved in the formation of these compounds. Show the removal of water and the reactant.
How much heat (in ) is required to warm 12.0 g of ice, initially at -11.0 degrees C, to steam at 111.0 degrees C? The heat capacity of ice is 2.09 and that of steam is 2.01 J/gC.
(a) Cl2(g) is added to the system. (b) The reaction mixture is heated. (c) The volume of the reaction vessel is doubled. (d) A catalyst is added to the reaction mixture. (e) The total pressure of the system is increased by adding a noble gas. (f) ..
Lactase, an enzyme found in the small intestine, cleaves the milk sugar lactose to yield glucose and galactose. Assuming that the km for lactose is 0.9mM, vmax is 3.5 micromole/min/mg lactase, 5.7 micromoles lactose is presesnt
A 1-in. thick steel plate measuring 10 in. in diameter is heated from below by a hot plate, its upper surface exposed to air at 80oF. The heat-transfer coefficient on the upper surface is 5 Btu/h ftoF and k for steel is 25 Btu/h ftoF.
show the calculation for the percent yield of K3[Fe(C2O4)3].3H2O using your actual yield and the theoretical yield
unused lead nitrate to the container marked"sodium nitrate". What could the student do to get all the led ions out from the sodium nitrate?
Phosgene is formed from carbon monoxide and chlorine. At 605 degrees C, Kc is approximately 15.5 M-1 or L/mol. Calculate Kp (in atm-1) at this temperature.
Verify that this is a first order reaction by plotting 1n ([C2H40]/M versus time and determine the value of the rate constant.
in a 50.0 l container 4.00 moles of chlorine and 2.00 moles of bromine are placed and kept at 293.0 k until equilibrium
Calculate the molarity of a solution of glycerol made by dissolving 66.000 mL glycerol at 15 ^circ {rm C} in enough water to make 400.00 mL of solution.
the rate of disappearance of HBr in the gas phase reaction 2HBr(g)-->H29(g)+Br2(g)is .301 at 150 degrees celsius. what is the rate of appearance of Br2?
