1. Write a balanced chemical equation, including state subscripts, for the double displacement reaction between lithium hydroxide and ammonium bromide.
2. What would most likely happen if two solutions in which the positive ions of each compound are alkali metals were combined?

im not exactly sure but i think its b!

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

i think is conclusions.i think so
