Calculate the mass, in grams for a gold sample that absorbs 225 J to change its temperature from 15 Celsius to 47 degrees celsius.
Which satisfy the octet rule and which do not? PS3, SO2, SO3, NO3-1, CO3-2, PCl5
Reactions within equations and properties of acidity, A reaction occurs for each of the following below. How do you differentiate between the different driving forces? (a driving force can either be the transfer of electrons; the formation of a pr..
A certain weak acid, HA, is titrated with Ka 5.61x10^-6 naoh. More strong base is added until the equivalence point is reached. What is the pH of this solution at the equivalence point if the total volume is 56.0
Determine the number of moles of CO2 that could be produced from the combustion of 0.00993 moles of Benzene
A solution of M(NO3)2 is electrolyzed. When a constant current of 2.50 amperes is applied for 35.0 minutes, 3.06 grams of the metal M is deposited. calculate the molar mass of M and identify the metal
The reaction of water and coal at a high temperature produces a mixture of hydrogen and carbon monoxide gases. This mixture is known as syntheses gas (or syngas). How many grams hydrogen gas can ne formed form the reaction 135g of water with exces..
Describe what happens to the temperature, the volume, and the phase composition ( number of moles of liquid or vapor present) following the removal of 750 J of heat from 1 mol of pure water initially in each of the following states.
Write an equation for the overall reaction in this experiment ( synthesis of salicylic acid from winter green oil) and use it to calculate the atom economy of the synthesis and your reaction efficiency
Primary alcohols can be oxidized to aldehydes and carboxylic acids. Often it is difficult to stop at the aldehyde oxidation state. One method frequently used to accomplish
the resulting solution required 38.10mL of 0.08765M AgNO3(aq)to precipitate the Cl(aq) and BrCl(s)and AgBr(s) calculate the mass percetage of NaCl(s)in the mixture
Many metals pack in cubic unit cells. The density of a metal and length of the unit cell can be used to determine the type for packing. For example, gold has a density of 19.32 g/cm3 and a unit cell side length a of 4.08 Å. (1 Å = 1. 10-8 cm.)
