How much solute will remain undissolved when 180 g of potassium iodide is added in 100 cm3 of water at 30°C?

Which element is the least metallic between cadmium, silver, zinc, or iron?

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?

Is 343 in the sequence -5, -2, 1, 4, 7
