Given the following list of ka values, determine which weak acid solution would have the highest concentration of [h+] (lowest ph value) at equilibrium assuming all acids have the same initial concentration.

a. hf(aq), ka = 6.3 × 10^−4
b. hc7h5o2(aq), ka = 6.4 × 10^−5
c. hn3(aq), ka = 1.9 × 10^−5

Select the correct answer from each drop-down menu. describe what happens to a carbon-11 atom when it undergoes positron emission. the decay of a carbon-11 atom _1_, and this causes it to emit _2_.options for 1: > changes a neutron into a proton> changes a proton into a neutron> is hit with a neutron> reconfigures its protons and neutronsoptions for 2: > a negatively charged electron-sized particle> a positively charged election-sized particle> two atoms and several neutrons> two neutrons and two protons
