An element x forms an iodide (xi3­) and a chloride (xcl3). the iodide is completely converted to the chloride when it is heated in a stream of chlorine: 2xi3 3 cl2 → 2xcl3 3i2. if 0.5000 g of xi3 is treated, 0.1635 g of xcl3 is obtained. identify the element x (write down the atomic symbol for x).

What is a scientific theory? a. a scientist's guess about how something works b. the results of an experiment obtained using the scientific method c. a proven fact that will never change d. an idea that is backed by data from many sources

Analyze how limestone is weathered and identify the features that are formed as a result of this dissolution

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?
