how perpetual and periodic differ explain how the perpetual and periodic inventory systems differ, especially in determining Cost of Goods Sold and Ending Inventory? Once a retailer has chosen the inventory costing methods: First-In-First-Out(FIFO), Last-In-First-Out(LIFO), weighted average and specific identification. In times of changing inventory prices (both inflation and deflation) how can the choice of […]
Aggregate Demand Shift why does an increase in money supply cause the aggregate demand increase and shift?
Kinetic Energy The system shown is released from rest. Given H=20.0m, ?=30.0o, the coefficient of kinetic friction between m and the incline plane is .300, m=30.0kg, M=60.0kg; then, what is the kinetic energy of m as it starts from rest and moves a distance of 10.0m up the incline plane? The pulley has …

Titration – Calculate thr %m/m Mn3O4. A 0.200 g sample is analyzed for manganese as follows. Add 50.00 mL of 0.100 M ferrous ammonium sulfate to reduce MnO4 to Mn. After reduction is complete, the excess ferrous ions is titrated in acid solution with 0.0200 M KmnO4, requiring 15.0 mL. Calculate thr %m/m Mn3O4.
Physical Chemistry Virial Pressure a) What is the virial pressure of 0.693 moles of O2S gas at 350K in a 1000 cm3 container, given B = -7 cm3mol1-? atm (Report to 2 significant figures.) b) The sign of the virial coefficient indicates ________ are present under these conditions. 1) repulsions 2)attractions c)If the temperature of […]
Henderson-Hasselbalch equation Carbon dioxide (CO2) and bicarbonate (HCO3?) concentrations inthe bloodstream are physiologically controlled to keep blood pHconstant at a normal value of 7.40.
using Carbon-14 to determining age An organic sample (3 grams mass) is taken from an archeological site. The sample has a beta emission rate of 4.3 counts per minute. These decays originate predominantly from carbon-14 with a half-life of 8270 years. If the abundance of carbon-14 in living matter is 1.2e-12, what can you deduce […]
