Question

when 2.76 (0.0200 mol) of k2co3 was mixed with 30.0 ml of approximately 2 M HCL the temperature rose by 5.2 C

how do i write a balanced equation for problems like this?
bobpursley
K2CO3+ HCl (aq)>>CO2+K2O+H2O> KOH +CO2

Note the second reaction is with K2O with the water that accompanies the acid. 2M HCl is mostly water.
