Yup, that works now. Thanks

What I did was subtracted the moles of H+ from moles of OH-, giving an answer of 0.0001 moles of H+ left over. I then stupidly went straight to the pH equation and got -log(0.0001) and got an answer of 4 out, which is wrong

Test No. 10008896 : Results - Online Multiple Choice Sadly they wanted an answer of 2.7

Could someone please show me how to do this: 20mL of 0.08 mol/L HCl is added to 30mL of 0.05 mol/L of NaOH Calculate the pH of the solution Thanks

As sulfuric acid is diprotic (H2SO4), there will be a concentration of 0.4 moles of H+ ions in a 0.2 molar solution thus we use the formula pH=-logH+ pH=-log(0.4) pH=0.699

the structure of CH3COOH means that the OH cannot isonise, as it is bound to the carbon, meaning that only the H will ionise, leaving CH3COO-

Unless the 1.3% is specified, we assume it ionizes 100% so it becomes -log(0.001) which equals 3

So, I check the HSC Syllabus, and it turns out my school is unable to format a f**king table. They meant to say "Christianity as a major religious tradition", but instead they made tradition its own dot point Thanks, St Aloysius RE department!

So, im doing my 2U RE Assignment, and have been having no problems with it, but there is one particular dot point in the syllabus that I can't seem to get any notes on: "Account for the present religious landscape in Australia in relation to the following: -Christianity as the major religion...
