Calculate the percent error in calculating the ph of a 0.040 m hcl solution that is also 0.010 m in hno3 using ionic strength and activity coefficients and without using that. you can use the value without using ionic strength as the experimental value.

The answer for #3 is c but i don't know why

Afamily is one another name for a group on the table of elements.

The reactions shown here can be combined to make the overall reaction c(s) + h2o(g) ⇌ co(g) + h2(g) by reversing some and/or dividing all the coefficients by a number. a. c(s) + o2(g) → co2(g) k=1.363×10^69 b. 2 h2(g) + o2(g) → 2 h2o(g) k=1.389×10^80 c. 2co(g) + o2 (g) → 2 co2(g) k=1.477×10^90
