The specific heat of silver is 0.24 cal/goC. How many joules of energy are needed to warm 4.37 g of silver from 25.0 oC to 27.5 oC?

List the two type of transporst that the cell in orde to transport molecules acroos the membrane

How might this scientific phenomena be explained? a paper clip floats on water.

What is the typical rotational frequency frot for a molecule like n2 at room temperature (25∘c)? assume that d for this molecule is 1å=10−10m. take the total mass of an n2 molecule to be mn2=4.65×10−26kg. you will need to account for rotations around two axes (not just one) to find the correct frequency. express frot numerically in hertz, to three significant figures.
