A sample of Element X is found to contain 72.15% of isotope type 1 (84.91 amu) and 27.85% of isotope type 2 (86.91 amu). Calculate the average atomic mass.

Hbr dissociates to form h+ and br-ca(oh)2 dissociates to form ca2+ and 2oh-the h+ and oh- react to form waterassuming the reactants are dissolved in water, the net reaction is h+ + oh- —> h2oif you’re asked to show all components of the reaction, the complete reaction is 2hbr + ca(oh)2 —> cabr2 + 2h2o

Reaction type : double replacement hcl + lioh = h2o + licl

Answer(false);
