Shatter into tiny pieces
The crystal may break due to the fall.
Answer:
To balance the reaction, we should put a 4 in front of Al
Explanation:
<u>Step 1:</u> Data given
AI+3O2->2AI2O3
<u>Step 2:</u> Balance the equation
On the right side we have 2*3 = 6 oxygen atoms
On the left side we have 3*2 = 6 oxygen atoms as well, so those are on both side balanced
On the right side we have 2*2 = 4 Al atoms
On the left side we have only 1 Al atom
We should multiply this by 4 (place a 4 in front of the Al)
4AI + 3O2 → 2AI2O3
Now al atoms are balanced on both sides.
I believe the answer you're looking for is O=C=O !
The equation for the reaction describe in the question is NH4Cl (s) --> NH3 (g) + HCl (g)
the equation of heat reaction :
ΔH25° = (ΔH25° NH3 + ΔH25° HCl) - (ΔH25° NH4Cl)
use the table from basic chemical engineering calculations of himmelblau or felder to find ΔH25°.ΔH25° of products minus ΔH25° of reactants.
hope this help
