a solution is prepared at 20 degrees celsius and its concentration is expressed into different units molarity and molality the solution is then heated to 88 degree celsius which of the concentration units will change

In this chemical reaction, 325 grams of barium (ba) react completely. how many moles of lithium (li) are produced?

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?

Which material burns faster? metal aluminum
