A compound<span> is a </span>pure substance<span> composed of two or more different atoms chemically bonded to one another. A </span>compound<span> can be destroyed by chemical means. It might be broken down into simpler </span>compounds<span>, into its elements or a combination of the two.</span>
I think it's A, <span>an action which causes movement and an opposite reaction</span>
Hydrogen is the limiting reactant because when doing a stoichiometry equation for the reactants, hydrogen will be used completely by having a smaller yield and oxygen will be excess (7 moles to be exact)
C + H2O -> H2 + CO
n(C) = 15.9/12 = 1.325 (mol)
=> n(H2) = 1.325 mol
We have:
PV = nRT
=> V = (nRT)/P
(R = 22.4/273 = 0.082)
V = (1.325 x 0.082 x 360)/1 = 39.114 (L)
The answer would be KMnO4, please let me know if you would like me to explain how i got this
