PLEASE ANSWER ASAP Marika wants to collect a precipitate of Ca(OH)2. So she makes a 0.01 M
solution of NaOH and mixes it with a 0.05 M solution of Ca(NO3)2. She finds
that the reaction is very slow. What would be the best way to increase the rate
of the reaction?
O A. She could make the original solutions at lower concentrations.
B. She could use less of each solution.
C. She could reduce the temperature of the solutions.
D. She could make the original solutions at higher concentrations.

Ineed this asap part i: scientific method what is the difference between science and pseudoscience? what is the scientific method?

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?

Consider the following reaction at equilibrium: c(s)+h2o(g)⇌co(g)+h2(g) predict whether the reaction will shift left, shift right, or remain unchanged upon each of the following disturbances. a) c is added to the reaction mixture. b) h2ois condensed and removed from the reaction mixture c) co is added to the reaction mixture d) h2 is removed from the reaction mixture.
