High density is the most likely answer
I am pretty sure the answer is D. That the patterns of a polarity matched up on both sides.
Answer:
0.07
Explanation:
to find mole you divide mass by the relative atomic mass
Now you find the relative atomic of of moles pf he number sodium sulfide
then you thequation for finding moles to find mole of sodium
<u>Answer:</u> The ionic compound formed is (barium fluoride)
<u>Explanation:</u>
Ionic compound is formed by the complete transfer of electrons from 1 atom to another atom. The cation is formed by the loss of electrons by metals and anions are formed by gain of electrons by non metals.
Taking the metal as barium and non-metal as fluorine.
Barium is the 56th element of the periodic table having electronic configuration of
This element will loose 2 electrons and will form ion
Fluorine is the 9th element of the periodic table having electronic configuration of
This element will gain 1 electron and will form ion
By criss-cross method, the oxidation state of the ions gets exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound.
Hence, the ionic compound formed is (barium fluoride)
Low pressure and low temperature as the lower these are, the lower the kinetic energy is.
