Combustible: Charcoal, straw, cardboard, paper, candle, wood.

There would be no nobr and it would just be 2
H2SO4 ---> 2H^+ + SO4^2-
Hence n H+ = 9 mols
Mass of H = nM = (9*1) = 9g
Alternately
mass of H2SO4= nM= 4.5*98= 441
Mass of H= mass h2so4 * molar mass of H/molar mass of h2so4
Mass of H= 441 * 2/98 = 9g
<span>the si unit of temperature is its degree celsius because its online you could've just looked it up </span>
