closing inventory (under perpetual system): 125,000 x 30% = \$37,500 (Income statement and bal sheet) Sales Revenue : \$162,500 (Income Statement) Cost of goods sold (expense): 125,000 x 70% = \$87,500 (Income Statement) Gross profit: 162,500 - 87,500= \$75,000 (Income statement) ...

Chemistry
Suppose that 2.00 mol of HNO2 is dissolved in 1.00L of water at 25 degrees C. Because HNO2 is a weak acid, it is in equilibrium with the ions, H+ and NO2-. What are the concentrations of these ions at equilibrium?

Chemistry
A l.00L flask contains 4.40mol of HI at a certain temperature. The Keq at this temperature is 5.0 * 10^-4. What are the concentrations of H2 and I2 at equilibrium?

Chemistry
Which value of Keq indicates most favorability of product formation, Keq = 1 * 10^12, Keq= 1.5 or Keq= 5.6 * 10^-4?

A broom handle has a length of 1.67m and a mass of 580g with the axis rotation through the center. (what is this problem asking me to do?)

I have no idea where to start with this problem: A certain reaction has the following general form: aA -> bB At a particular temperature and (A)o = 2.00(10^-2)M, concentration versus time data were collected for this reaction, and a plot of In(A) versus time resulted in a s...

A bolt is to be tightened with a torque of 8.0 N*m. If you have a wrench that is 0.35 m long, what is the least amount of force you must exert? the equation for this problem is t=Fr sinbeta, but the sin is not given What am I suppose to do?

Math
So after i do all that should i get one whole number
