The carbon cycle can be described using chemical reactions. When carbonate rocks like limestone and silicate rocks like sandstone are metamorphosed, the components may react with each other: CaCO3 + SiO2 CaSiO3 + ? What is the missing product in this chemical equation? What does the equation tell you about the role of metamorphism in the carbon cycle?

What does the xylem do? stores the glucose captures the sunlight absorbs oxygen into the leaf carries water from the roots to the leaves

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?
