just multiply the concentration of Bx2=1.10Mx2L=2.2moles and then subtract the moles of A from calculated moles of B 5.00-2.2=2.8moles

Step 1: Determine amount of dividends that preferred shareholders are entitled to: 5000*100*5% = 25,000 Step 2: Determine amount of earnings left over for common shareholders after the payment of preferred dividends: 105,000-25,000 = 80,000. Step 3: Use the EPS formula to ...

it depends on whether the reactant or product is solid or liquid. If it's solid you don't suppose to include in finding equilibrium concentration and the eq. will look like Kc=[B][C]

Physical Science
a=v-u/t where a, is the acceleration,v the final velocity,u the initial velocity and t the time.=a=x ,v=15ms`,u=0 and t=10 therefore from a=u-v/t you have a=15-0/10=1.5ms`2

what is the answer?

12 pounds of A grade coffee and 8 pounds of B grade coffee.
