Answer:
C) 0.121 M
Explanation:
HCl + H₂O = H₃O⁺ + OH⁻
.121M .121M
HCl is a strong acid . It will dissociate almost 100 % so the concentration of acid and hydronium ion formed will be equal . It is to be noted that hydronium ion is formed due to association of H⁺ and H₂O . H⁺ is formed due to ionisation of HCl .
So concentrtion of hydronium ion ( H₃O⁺ ) will be .121 M.

1 mol = 143.092 g = formula units
Henceforth –
formula units –
Answer:
58
Explanation:
Due to conservation of energy, the sum of the reactants = the sum of the products. So 28 + 30 = 58g
4FeS2 + 11O2-> 2Fe2O3 + 8SO2
Not sure.... I think this is it
