Heres a balanced equation: Na2CO3(aq)+2AgNO3 (aq) --> 2NaNO3(aq)+Ag2CO3 (s) From this equation, 10 mL of AgNO3 in this contains 34 grams of AgNO3. Calculate the grams of solid product, Ag2CO3. Part 2: 10 mL of Na2CO3 in this experiment contains 21 grams of Na2CO3. Calculati...
help- e^1-5x=3 find solution to 4 decimal places. I don't know how to type it in to my calculator!
It wont take long to clean, but you cant do it. Your clothes are on the floor, and games are everywhere.
use x = x0 + v0*t + 1/2*a*t^2 v = v0 + a*t where x is position, x0 is initial position, v0 is initial speed, a is acceleration/deceleration, t is time, and v is speed as a function of time a) 56 - 6.2*t^2 = 0 Solve for t, the time it takes for the speed to go to zero. The dist...

After one second, when the patrol car is at location x = 0, the student is at 45 m. The student's location as a function of time, where t=0 when the police car starts accelerating is 45 + 45*t The policeman's position is 1/2*3*t^2 Set these two equations equal to each ...
Force = mass*acceleration Since the book is at rest in your hands and not moving, the net force is 0.
First, find the x and y components of all vectors: Ax = -6.2*cos(52) Ay = 6.2*sin(52) Bx = 6.6*cos(27) By = 6.6*sin(27) Cx = 2.8*cos(57) Cy = -2.8*sin(57) Dx = Ax - Bx + 3*Cx Dy = Ay - By + 3*Cy D has a magnitude of D = (Dx^2 + Dy^2)^0.5 and a direction of theta given by tan(t...
v(air) = lambda*fair where lambda is the wavelength, fair is the frequency in air v(helium) = lambda*fhelium v(air)/v(helium) = f(air)/f(helium) Look up the speed of sound in air and solve for f(helium)
the fourth standing wave frequency is 4*f1, where f1 is the fundamental wave frequency. The seventy fundamental frequency is 7*f1 7*f1 - 4*f1 = 3*f1 = 144 hz f1 = 144/3
