Answer:
organs is the right answer
Answer:
Ba(NO2)2
Explanation:
Anything that contains calcium comes from a strong acid. Nitrous oxide (NO2) is a weak acid, therefore the salt it makes is less acidic than the rest --> the highest pH :)
The reaction H2SO4 + 2 NaOH -> Na2SO4 + 2H2O applies to an acid-base titration.
moles NaOH = c · V = 0.2423 mmol/mL · 32.23 mL = 7.809329 mmol
moles H2SO4 = 7.809329 mmol NaOH · 1 mmol H2SO4 / 2 mmol NaOH = 3.9046645 mmol
Hence
[H2SO4]= n/V = 3.9046645 mmol / 37.21 mL = 0.1049 M
The answer to this question is [H2SO4] = 0.1049 M
I believe it is H--CH3, as the difference in electronegativity is larger
