Nitrogen and hydrogen can react to form ammonia. n2(g)+3h2(g)→2nh3(g) part a choose ratios showing the relationships between moles of each of the reactants and products in the reaction. choose ratios showing the relationships between moles of each of the reactants and products in the reaction. 1 mol n2 : 3 mol h2 : 2 mol nh3 2 mol n2 : 2 mol h2 : 3 mol nh3 1 mol n2 : 1 mol h2 : 1 mol nh3 1 mol n2 : 1/3 mol h2 : 1/2 mol nh3

A+b→2c when the reaction begins, the researcher records that the rate of reaction is such that 1 mole of a is consumed per minute. after making changes to the reaction, the researcher notes that 2 moles of a are consumed per minute. what change could the researcher have made to effect this change?

Particle model to predict what will happen if a sharp object creates a hole in the soccer ball

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?
