Well, in order to obtain the mass of the gas in grams, we have to find out the number of moles. Since the eqn is Moles = Mass(g)/ar or mr and if we reconfigure the eqn to Mass= moles × ar or mr. To find out moles, we have to derive it from the concentration of it since concentration= Mol/dm3 amd if we reconfigure the eqn to moles= concentration × dm3, we can obtain the numner of moles. After that, imput the number of moles into the eqn: mass= moles × ar or mr. Tada.
Oh yeah, you must know what is the gas in the tank. If not, it is impossible.
Ar means relative atomic mass
Mr means relative molecular mass.
Answer
D. The gas molecules in both containers have the same average kinetic energy.
Explanation:
Answer:
Explanation:
Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.
k= rate constant
m = order with respect to A
n = order with respect to B
Total order = m+n
is ideal gas equation
is vant hoff equation.
is equilibrium constant.
Answer:
the first one is protons and electrons the second one is protons the third one is neutrons and the forth one is also neutron
Answer:
The two-step mechanism is a slow mechanism and a fast mechanism. When we combine them, the result is
2H₂O₂ (aq) ⇒2H₂O (l) + O₂ (g)
Explanation:
We know that the decomposition of hydrogen peroxide is catalyzed by iodide ion, which means that the iodide ion will react with the hydrogen peroxide. There is a slow mechanism and a fast one:
H₂O₂(aq) + I₋(aq) ⇒ H₂O(l) + IO₋(aq) this is the slow reaction
IO₋(aq) + H₂O₂(aq)⇒ H₂O(l) + O₂(g) + I₋ (aq) this is the fast reaction
If we cancel the same type of molecules and ions, the final result is:
2H₂O₂ (aq) ⇒2H₂O (l) + O₂ (g)
