Hello!
1) What is the limiting reactant?The chemical equation for this reaction is:
2Al(OH)₃ → Al₂O₃ + 3H₂OThe
Limiting Reactant is the one that is in the lowest amount in the reaction and determines how many moles are produced. You can see that in this chemical equation there is only one reactant since this reaction is a
decomposition reaction. So,
the limiting reactant is Al(OH)₃.2) How many grams of water are produced?The chemical equation for this reaction is:
2Al(OH)₃ → Al₂O₃ + 3H₂O
So, we are going to use the following conversion factor to go from grams of Al(OH)₃ to grams of water:
So,
6,17 grams of Water are produced.
Have a nice day!
Answer:
D
Explanation:
Without gravity, any object wont go to the ground, and without a magnetic field, a compass cant be used for navigation.
The order of the planets based on the distance from the sun is...
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.
We can write the balanced equation for the galvanic cell by using the oxidation and reduction half-reactions. In the anode, Ni(s) is oxidized and produces aqueous Ni2+:
Ni(s) → Ni2+
while in the cathode, Cu2+ is reduced and deposits copper:
Cu2+ → Cu(s)
We now balance the charge of each reaction by adding electrons to the side of the equation with the greater charge:
Ni(s) → Ni2+ + 2 e-
Cu2+ + 2 e- → Cu(s)
Finally, we add the half-reactions to obtain the overall balanced equation for the galvanic cell:
Cu2+(aq) + Ni(s) → Ni2+(aq) + Cu(s)
