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
Answer:
i think the answer is C
Explanation:
not sure plsss dont bash im a beginner
<span>K3Fe(CN)6
K - 3 atoms
Fe - 1 atom
C - 6 atoms
N - 6 atoms
Altogether : 3+1+6+6= 16 atoms</span>
Because more than one substance was released (following a color change signifying a chemical reaction), the sample was indeed, a compound.
Sodium is a very reactive metal. It is kept in kerosene to prevent it from coming in contact with oxygen and moisture. If this happens, it will react with the moisture present in air and form sodium hydroxide.
