There are a few major types of reactions that occur. In a synthesis reaction, pure substances come together. They form a chemical bond and produce new compounds. A synthesis of 2H_22 and O_22 results in 2H_22O, also known as water. In a decomposition reaction, the inverse occurs; a compound's chemical bonds break. Both synthesis and decomposition result in new substances but not new atoms, and no matter is created or destroyed. synthesis can best be described as

a. the opposite of decomposition.

b. the same as decomposition.

c. the result of decomposition.

d. the cause of decomposition

ur answer would be b hope i let me know if it is right

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).
