In a beaker, you are given a solution of salt water, with a density of 1.025 g/mL. You place in a wooden cube with a mass of 5g and a volume of 10mL. What will the wooden cube do?

7. what temperature is need to just dissolve 50 g of nh4cl in 75 g of water? '

Give the orbital configuration of the phosphorus (p) atom.

The ozone molecule o3 has a permanent dipole moment of 1.8×10−30 cm. although the molecule is very slightly bent-which is why it has a dipole moment-it can be modeled as a uniform rod of length 2.5×10−10 m with the dipole moment perpendicular to the axis of the rod. suppose an ozone molecule is in a 8000 n/c uniform electric field. in equilibrium, the dipole moment is aligned with the electric field. but if the molecule is rotated by a small angle and released, it will oscillate back and forth in simple harmonic motion. what is the frequency f of oscillation?
