Given the balanced equation representing a reaction: 2H2 + O2 -> 2H2O + energy Which type of reaction is represented by this equation?

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 its 100

i hope this !

the objects have the same charge is correct.
