Answer:

The simplest formula is C₃H₅.

Explanation:

The moles of CO₂ are the moles of Carbon because oxygen is in excess. Thus, the double of moles of H₂O are the moles oh hydrogen (Double because H₂O has two hydrogens for each mole).

4,822g CO₂ × (1mol / 44,01 g) = 0,1096 moles of C

1,650g H₂O × (1mol / 18,01 g) × 2= 0,1832 moles of H

The next step is divide these numbers between the smaller one, thus:

0,1096 moles / 0,1096 moles = 1

0,1832 moles / 0,1096 moles = 1,672

The last step is to find a number to multiple that gives integers:

1 × 3 = 3 Carbon

1,672 × 3 = 5 hydrogen

Thus, the simplest formula is C₃H₅.

I hope it helps!

Consider the following chemical equilibrium:
jok3333 [9.3K]

Answer:

Kc = [CH₄] / [H₂]²

Kp = [CH₄] / [H₂]² * (0.082*T)^-1

Explanation:

Equilibrium constant, Kc, is defined as the ratio of the concentrations of the products over the reactants. Also, each concentration of product of reactant is powered to its coefficient.

<em>Pure solids and liquids are not taken into account in an equilibrium</em>

Thus, for the reaction:

C(s)+ 2H₂(g) ⇌ CH₄(g)

Equilibrium constant is:

<h3>Kc = [CH₄] / [H₂]²</h3>

Now, using the formula:

Kp = Kc* (RT)^Δn

<em>Where R is gas constant (0.082atmL/molK), T is the temperature of the reaction and Δn is difference in coefficients of gas products - coefficients of gas reactants (1 - 2= -1)</em>

Replacing:

<h3>Kp = [CH₄] / [H₂]² * (0.082*T)^-1</h3>

Determine the enthalpy of solution for a solid with δh values as described in each scenario.
IrinaVladis [17]

Answer : To determine enthalpy of solution for a solid with δH values.


One can use the equation as H (reaction) = H (products) - H (reactants)


If δH values are known one can simply substitute them in the above equation and get the enthalpy of the required solution.
