This is worth 30 points During an experiment, the percent yield of calcium chloride from a reaction was 85.22%. Theoretically, the expected amount should have been 113 grams. What was the actual yield from this reaction?
Caco, + HCI - CaCl2 + CO2 + H20 (5 points)
1.96.3 grams
2.99.0 grams
3.113 grams
4. 121 grams

In a chemical reaction at equilibrium, the rate of the forward reaction the rate of the reverse reaction. if the rate of the forward reaction more products are formed.

If 22.5 liters of oxygen reacted with excess of hydrogen, how many liters of water vapor could be 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?
