<span>Answer: The activation energy for the reverse reaction is equal to the sum of the absolute value of DH + Ea(forward) or 275 kJ + 125 kJ = 400 kJ If you just sketch an energy diagram showing the activation energy and Delta H for the reaction, it should be apparent why this is the case.</span>

In two or more complete sentences, explain how to balance the combustion equation: ___C5H12 + ___O2 ⟶ ___CO2 + ___H2O
egoroff_w [7]

Answer:

First, place no. 5 in front of the CO2 in order to balance the carbon atoms. Next, place no. 6 in front of H2O to balance the hydrogen atoms. Lastly place no. 8 in front of the O2 so that there are 16 oxygen atoms on both sides of the reaction.

if a volume of air occupying 12.0Lat 20celsius is heated to a new temperature of 100 celsius,what would be the new volume
emmasim [6.3K]

Answer:

V₂ = 15.3

Explanation:

Given data:

Initial volume = 12.0 L

Initial temperature = 20°C

Final temperature =100°C

Final volume = ?

Solution:

First of all we will convert the temperature into kelvin.

20°C + 273 = 293 K

100°C + 273 = 373 K

Formula:

V₁/T₁ = V₂/T₂

V₁ = Initial volume

T₁ = Initial temperature

V₂ = Final volume  

T₂ = Final temperature

Now we will put the values in formula.

V₁/T₁ = V₂/T₂

V₂ = V₁T₂/T₁  

V₂ = 12.0 L × 373 K / 293 k

V₂ = 4476 L.K /293 k

V₂ = 15.3

V₂ = 1566 L.K / 298 K

V₂ = 5.3 L

Does this graph represent an endothermic or exothermic chemical reaction? Explain your reasoning. ​
Natali [406]

Answer:

it is an exothermic reaction

Explanation:

exothermic reactions have a negative ∆H

i.e, product of the reaction is less that the reactants of the reaction

(Note : ∆H= products - reactants), that's why it's exothermic
