It is not specified whether charge is +1 or -1.
If charge is +1, then total no. of electrons is 110,and so is atomic number.
Mass No.=No. of neutrons+ Atomic Number (1)
=159+110=269
If Charge is -1, total no.of electrons= 108= atomic number
From (1)
Mass No.= 159+108=267
Hope It Helped :)
Increasing the pressure will shift the equilibrium toward the left.
<span>Since N2O4 is colorless and NO2 is brown, you would expect increasing the pressure would make the color lighter.</span>
Atoms are electrically neutral because they contain equal quantities of positively charged protons and negatively charged electrons. Electrons and protons have equal but opposite charges, so the result is no net charge. Ions are atoms that have gained or lost electrons. As a result, ions have a net charge.
