The hydronium and hydroxide concentrations of a solution that is 5.0 x 10-3 M H2SO4 is 2.7.
pH= -log[H+] - (i)
10^-3=H2So4
H+= 2×10-3
here ,
h2so4 ——— 2[H+] + so4^2-
thus [H+]= 2*10^(-3) because hydrogen ion has two moles
pH= -log[H+]
pH= -log(2×10^-3)
pH= 3-log2
pH= 3-log2pH= 2.7
The pH is 2.7
<h3>What is pH?</h3>
PH is the degree of alkalinity and acidicity in a solution.
Therefore, The hydronium and hydroxide concentrations of a solution that is 5.0 x 10-3 M H2SO4 is 2.7

Answer:
Density, mass of a unit volume of a material substance
Explanation:
Answer: Some signs of a chemical change are a change in color and the formation of bubbles. The five conditions of chemical change: color chage, formation of a precipitate, formation of a gas, odor change, temperature change.
Answer:
15.41.
Explanation:
- From the balanced equation:
<em>2SO₂(g) + O₂(g) ⇄ 2SO₃(g).</em>
<em />
The equilibrium constant = Keq = [SO₃]²/[SO₂]²[O₂].
<em>∴ Keq = [SO₃]²/[SO₂]²[O₂]</em> = (0.56 mol/L)²/(0.344 mol/L)²(0.172 mol/L) = <em>15.41.</em>
