The ratio of moles of AI(NO3)3 to moles Na2CO3 in the reaction is 2:3
In the reaction 2 moles of AI(NO3)3 reacted with 3 moles Na2CO3 so the ratio of the moles is 2 is to 3 represented as 2:3
hope it helps
Answer:
There is no deacceleration.
Explanation:
Let's check relation between velocity and acceleration
So as velocity graph is going up acceleration is going up
Those flat lines on graph shows constant acceleration .
Curve lines up shows instantaneous acceleration.
If the graph is going down then it can be deacceleration .
Note :-No F is present in graph
The signs of ΔS° and ΔH° will be negative.
A combustion reaction is a reaction in which a substance reacts with oxygen gas, releasing energy in the form of light and heat.
Combustion reactions must involve O2 as one reactant.
Consider the combustion of butane gas:
C₄H₁₀(g ) + 13/2O₂(g) → 4CO₂(g) + 5H₂O(g)
4 + 13/2 4 + 5
10.5 mol -------------> 9 mol
As the number of moles decreases entropy will decrease
so ΔS° = negative
since this example for combustion reaction heat is released (exothermic)
so ΔH° = negative.
