Density of phosgene gas, COCl2(MM=99) ander a certain condition is 4.5g/L. What is the density if H2S gas(MM=34) under the same conditions?

The enthalpy of combustion of benzoic acid,C6H5COOH, which is often used to calibrate calorimeters, is -3227kJ/mol. When 1.236g of benzoic acid was burned in a calorimeter, the tempurature increased by 2.345K. What is the specific heat of the calorimeter?

How do you graph abs(y)=x

A race car moves such that its position fits the relationship x = (5.0 m/s)t + (0.75 m/s3)t3 where x is measured in meters and t in seconds. (a) Plot a graph of the car s position versus time. (b) Determine the instantaneous velocity of the car at t = 4.0...

A glider on an air track carries a flag of length through a stationary photogate that measures the time interval [box]td during which the flag blocks a beam of infrared light passing across the gate. The ratio vd = l(italicized)/[box]td is the average vel...

Generate a function that models the situation. Consider the type of function described—it is not linear! A shipping company charges $4 for the first pound and $3 for each additional pound or part thereof. As you try to come up with the equation, consider...

BMI (body mass index).

or abs(y)>= x

| y | ¡Ý x

thanks

I still don't get it. could you answer (a) and (b) in two parts.

I think it's 'is' because the jury is 'a' group of people.

and the flag is of length l(italicized)

yes but what is the function?

What is the y= function? That's what i don't know.

Thanks I figured it out :)

f(x)=4+3*[[x]]
