If 5.0 moles of C3H8 react, how many molecules of water are formed?
Lady_Fox [76]
 <span>Propane is C3H8 

The balanced equation is: 
C3H8 + 5 O2 --> 3 CO2 + 4 H2O 
From the balanced equation you can see that for each mole of C3H8 you obtain 4 moles of H2O. 

moles H2O = 5.0 moles C3H8(4 moles H2O/1 mole C3H8) = 20 moles H2O formed 

Use Avogadro's number to find the number of molecules. 
molecules H2O = 20 moles H2O(6.02 x 10^23 molecules/1 mole) = 1.20 x 10^25 H2O molecules</span><span>

2 h2o ( g) 2 h2 (g) + o2 (g) kp = 7.8 × 10-16 at 930 k. give the value of kp for this reaction, if it is written as: 1/2o2 (g) +
trapecia [35]
When multiplying by a constant, raise Kp to the power of that constant.

When the reaction is reversed, it gives the inverse of Kp.

Kp^(-1/2) = (7.8 x 10^-16)^(-1/2) = 3.6 x 10^7

2A (g) + Y (g) &lt;-- --&gt; 3C (g) + D (g)
insens350 [35]

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]}

Next, according to an ICE table for this reaction, we find that:

[A]=2x

[Y]=x

[C]=0.651M-3x

[D]=0.754M-x

Whereas x is calculated by knowing that the [C] at equilibrium is 0.456M; thus:

x=\frac{0.651-0.456}{3} =0.065M

Next, we compute the rest of the concentrations:

[A]=2(0.065M)=0.13M

[Y]=0.065M

[D]=0.754M-0.065M=0.689M

Thus, the equilibrium constant for the leftwards reaction is:

K^{left}=\frac{(0.13M)^2(0.065M)}{(0.456M)^3(0.689M)}=0.0168

Nonetheless, we need the equilibrium reaction for the rightwards reaction; thus, we take the inverse to get:

K^{right}=\frac{1}{0.0168}=59.5

Therefore, the answer would be A. K = 59.5.

Regards!
