Calculate the mass of lead [0.0308 {\rm cal}/({\rm g} \times^\circ {\rm C})] that releases 53.5cal as the metal cools from 36.0^\circ C to 25.2^\circ C.
A 15.5g sample of titanium [0.125 {\rm cal}/({\rm g} \times^\circ {\rm C})] loses 32.6cal of heat.
If the initial temperature is 28.9^\circ C, what is the final temperature?
distinguish between an organic molecule that is dextrorotary and one that is levorotary.
The value of K_c or K_p for a stated chemical equation is equal to a constant at a given temperature. Also, and most importantly, if you want to make $25, add me on skype (kasparov586)
Calculate the hydronium ion concentration and the pH after the addition of .25mL of .10 M HCl to each one. What accounts for the difference in hydronium ion concentrations? Explain this based on equilibrium concepts.
what is the chemical calculation to figure out the following: what mass of the indicated solute does the following solution contain: 17.8 ml of 0.119 M CaCl2
A 290 mL stock solution contains 2.3 M Ca(CN)2. When 100 mL of the stock solution is diluted to 125 mL, how many moles of CN- ions will be contained in the dilute solution
Assume that the specific heat and density of the resulting solution are equal to those of water [4.18 and 1.00 ] and that no heat is lost to the calorimeter itself, nor to the surroundings.
How many grams of H2 are needed to react with 3.10 g N2?
Consider the following equilibria for phosphoric acid. H3PO4 ? H+ + H2PO4- K1 = 7.11 x 10-3 H2PO4- ? H+ + HPO42- K2 = 6.34 x 10-8 HPO42- ? H+ + PO43- K3 = 4.22 x 10-13
When dealing with ICE tables and calculating Kb and such, how do you do the algebra to calculate x when x is NOT negligible?
Describe how you would make 500 mL of 0.150 M Na2SO4 given 1 kg of Na2SO4, a distilled water supply, a balance, anf a 500-mL volumetric flask.
