Gas Laws and Energy
I have another question. I've tried it and i keep getting it wrong. The average kinetic energy of a 1.85-g sample of argon gas in a 3.00-L bulb is 1.28e-22 J/atom. What is the pressure of the gas? What is the root mean square velocity of the argon atoms under these ...

Chemistry - Gas Laws
Liquid helium at 4.2 K has a density of 0.147 g/mL. Suppose that a 1.00-L metal bottle that contains air at 118K and 1.0 atm pressure is sealed off. If we inject 120.0 mL of liquid helium and allow the entire system to warm to room temperature (25 °C), what is the pressure...

Assume that RBCs live 100 days. How many must you make per second to keep your cell count constant? You have to have the population to do this. Assume the number of RBC in the blood is P Then the rate dying is P/100 days Then the rate of regeneration must be the same. So now, ...

Find the integrals. (show steps) (integral sign) xe^(4x^2) I think this how is how its done: (integral sign) xe^(4x^2) it's a u du problem let u=4x^2 so, du=8x dx now you have an x already so all u need is 8 inside and and 1/8 outside the integral [1/8] (integral sign) [8]...

find the integral secxtanxdx and if dy/dx= 2x/y^2 and y(o) = 3 then what is y(1) equal to and differentiate 2pi + 3secx secxtanxdx = Sin(x)/Cos^2(x)dx The integral is 1/Cos(x) + c dy/dx= 2x/y^2 and y(o) = 3 then what is y(1) equal to y^2 dy = 2x dx ---> 1/3 y^3 = x^2 + c y(...

math
What is the equation of the tangent line given the curve: y = (3+lnx)^2 at x = 1/e dy/dx = 2[3 + Ln(x))]*1/x at x = 1/e this is: 4*e y(1/e) = 4 The equation of the tangent line is thus given by: 4e(x-1/e) + 4
