A displacement is related to time as x = A sin (2πft), where A and f are constants. Find the dimensions of A. (Hint: A trigonometric function appearing in an equation must be dimensionless.)
Suppose some of the solid Calcium Hydroxide is inadvertently transferred along with a supernatant liquid for analysis. Will more, less, or the same amount of HCL titrant be used for analysis
Aldrin (an insecticide) has a logKow of 5.8, while atrazine (an herbicide) has a logKow of 2.6. Kow is the octanol-water partition coefficient (Spiro pp. 498). Which pesticide will bioconcentrate to a greater extent
If 26mL of 5.2M H2SO4 was spilled, what is the minimum mass of NaHCO3 that must be added to the spill to neutralize the acid? 2NaHCO3+H2SO4=Na2SO4+2H2O+2CO2
Silver chloride, often used in silver plating, contains 75.27% Ag. Calculate the mass of silver chloride required to plate 225 mg of pure silver.
Consider the compound (Z)-3-hexene (B). Draw the bondline structures of the isomers of this compound in the manner requested. i) an isomer E that is the most reactive or reacts at the fastest rate during an addition reaction.
You have a system with a movable piston that is isolated. The reaction inside the system is under adiabatic conditions. When the reaction (the burning of butane in oxygen) is started, the distance the piston traverses is 30.00 cm at 1.000 atm of p..
The surface area of an object to be gold plated is 49.7cm2 and the density of gold is 19.3g/cm3. A current of 3.25A is applied to a solution that contains gold in the +3 oxidation state. Calculate the time required to deposit an even layer of gold..
Write down the reactions that occurred in each test tube if no reaction occurred then put NR on the product side Test tube.
A student in the laboratory connects a 10-Ω resistor, a 15-Ω resistor, and a 20-Ω resistor in series and then connects the arrangement to a 50-V dc source.
In a reversible adiabatic expansion of an ideal gas, the pressure and volume are related PV^gama= Constant by . Show that the work of adiabatic expansion from P1, V1 to P2, V2 is W= P2*V2-P1*V1/ Gama -1
Would applying a high pressure stabilize the CsCl form, or the NaCl form of this compound? (hint: calculate the volume per formula unit)
An unknown amount of magnesium metal reacts with 100.0 mL 0f 0.100M aqueous hydrochloric acid. The final solution is acidic, and titrated to an endpoint using 0.150 M aqueous sodium hydroxide.
