I have 0.009 moles of CaCO3 and I needed to find how many moles of CO3 are in the CaCO3. I am just making sure I am doing this correctly. 0.009 mol CaCO3 x 60.01/100.09= 0.54g CO3 0.54g CO3/ 100.09g CaCO3 = 0.005 mol CO3
Homer Hickham and his buddies launched model rockets in the late 1950's when the US was trying to get a rocket into space. If homer launches a rocket from rest and its engine delivers a constance acceleration of 8.2 m/s^2 for 5.0seconds after which the fuel is used up by t...
After cruising at 75 mph down I-80 for 15 minutes on a roach trip, you hit traffic and travel at 15m/s for 15 minutes for the rest of trip. your average speed is 24.26 m/s. What if you were traveling at each speed for the same distance instead of time? What would your average ...

Physics. please help! due tomorrow!
Let W1 represent the work required to accelerate an object on a frictionless horizontal surface from rest to a speed of v. if W2 represents the work required to accelerate the same object on the same surface from a speed of v to 2v, then which one of the following is the corre...
calculate the relativistic mass of 1.81x10^24 photons (3.00 mol) with wavelength of 450 nm.
I know, I don't understand. I don't know violet light or red light either, we haven't learned mass of those.
y=(w-5)270 for w
A 5.20 package slides 1.57 down a long ramp that is inclined at 13.0 below the horizontal. The coefficient of kinetic friction between the package and the ramp is = 0.305 Calculate the work done on the package by friction. Calculate the work done on the package by gravity. Cal...
