A piece of silver of mass 362 g has a heat capacity of 85.7 J/C (celsius degrees). What is the specific heat of silver?
if 5.77 g of S is reacted with 10.0 g of O2, how many grams of SO3 will be produced?
The mass spec of a yellow, diamagnetic solid A, a neutral metal carbonyl, reveals a molecular ion peak of 390 amu. A fragmentation pattern consisting of sequential losses of 28 amu (CO) occured until m/z = 110 amu.
The highly reactive OH radical (a species with an unpaired electron) is believed to be involved in some atmospheric processes. The bond enthalpy for the oxygen-to-hydrogen bond in OH as 460 kJ/mol. What is the longest wavelength (in nm) of radiati..
The stock solution is 500 ?g/mL and you want to obtain a final concentration of 1?M. What volume of the stock solution do you need to make 10 milliliters of the 1 ?M solution? Also: What is the molar mass of PMA?
Determining Copper in Brass, 1st I titrated Na2S2O3 and determined the molarity to be 0.164. I am having trouble with the calculations for the dissolution of brass.
only hydrogen gas would be left as a product b. the equilibrium would shift to the left c. the equilibrium would shift to the right d. the equilibrium would remain unchanged
A solution is prepared by dissolving 17.75 g Sulfuric acid (H2S04;MW = 98.0g/mol) in 93.2 g of water. If the density of the solution is 1.1094g/mL, what is the molarity of the sulfuric acid?
