Select the false statement below:A. Fe has 2 outer electrons, 8 valence electrons, and 18 core electronsB. Fe2 is more paramagnetic (has more unpaired electrons) than Fe3 C. Fe3 is isoelectronic with Mn2 D. none of these ions (Fe2 , Fe3 , Mn2 ) have any electrons in the 4s subshellE. Cu, Ag, and Au all have electron configurations of ns1 nd10

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
