Hello!
<span>Carbonic acid is referred to as volatile acid because it is produced from a gas that evaporates quickly.
Volatility is the likeliness of a substance to vaporize. That is the tendency of the substance to pass to the gaseous phase. That means that these substances have a high vapor pressure. Coming from a gas, Carbonic Acid has a high tendency to pass to the vapor phase.
Have a nice day!</span>
Answer:
The air gap is too narrow to allow the air to circulate easily. This therefore reduces the rate of heat transfer by convection. The trapped air reduces the rate of heat loss through the window by conduction and convection. The room in the house therefore stays warmer for longer reducing heating costs
Answer:
A. K = 59.5
Explanation:
Hello there!
In this case, since this reaction seems to start moving leftwards due to the fact that neither A nor Y are present at equilibrium, we should rewrite the equation:
3C (g) + D (g) <-- --> 2A (g) + Y (g)
Thus, the equilibrium expression is:
![K^{left}=\frac{[A]^2[Y]}{[C]^3[D]}](https://tex.z-dn.net/?f=K%5E%7Bleft%7D%3D%5Cfrac%7B%5BA%5D%5E2%5BY%5D%7D%7B%5BC%5D%5E3%5BD%5D%7D)
Next, according to an ICE table for this reaction, we find that:
![[A]=2x](https://tex.z-dn.net/?f=%5BA%5D%3D2x)
![[Y]=x](https://tex.z-dn.net/?f=%5BY%5D%3Dx)
![[C]=0.651M-3x](https://tex.z-dn.net/?f=%5BC%5D%3D0.651M-3x)
![[D]=0.754M-x](https://tex.z-dn.net/?f=%5BD%5D%3D0.754M-x)
Whereas x is calculated by knowing that the [C] at equilibrium is 0.456M; thus:
Next, we compute the rest of the concentrations:
![[A]=2(0.065M)=0.13M](https://tex.z-dn.net/?f=%5BA%5D%3D2%280.065M%29%3D0.13M)
![[Y]=0.065M](https://tex.z-dn.net/?f=%5BY%5D%3D0.065M)
![[D]=0.754M-0.065M=0.689M](https://tex.z-dn.net/?f=%5BD%5D%3D0.754M-0.065M%3D0.689M)
Thus, the equilibrium constant for the leftwards reaction is:
Nonetheless, we need the equilibrium reaction for the rightwards reaction; thus, we take the inverse to get:
Therefore, the answer would be A. K = 59.5.
Regards!
Answer:
C₃H₈₍g₎ + 5O₂₍g₎→ 3CO₂₍g₎ + 4H₂O₍l₎
Explanation:
Propane is an alkane that burns in enough oxygen to produce carbon (iv) Oxide and heat as the only by products. Balancing the equation: The number of atoms of each kind on either side should be equal. Hydrogen on the left has eight atoms same as the right side after balancing, oxygen has 10 while carbon has 3 on each side.
