Aneutral lithium atom has 1 valence electron. a neutral bromine atom has 7 valence electrons. a chemical reaction between the 2 forms lithium bromide. what electrical charges would the 2 newly formed ions take on? a. li- and br- b. li+ and br- c. li- and br+ d. li+ and br+

I believe the Lithium will give up its electron to the bromine so it would become negative

 so it is Li- and Br+

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.
