Write a written response for 40 points + ! explain the impact that changing concentrations has on a system in a state of dynamic equilibrium. what will happen when reactants are added to a reversible reaction mixture at equilibrium?

adding additional reactant to a system will shift the equilibrium to the right, towards the side of the products.

reversible reactions are usually self-correcting. If they are thrown off balance by a change in concentration, temperature, or pressure, the system will naturally shift to re-balance itself.

hope this helps

According to Le Chetelier’s Principle, in a dynamic equilibrium when a stress is applied to the system, the equilibrium shifts in such a direction to minimize the stress.

When reactants are added to a reversible reaction mixture at equilibrium, the reactants will get consumed and more of it will get converted to products. Thus the equilibrium will shift to the product side or the right side of the equilibrium.

that tool would be a compass

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).
