Answer:

a. CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(g)

Explanation:

En la representación que tienes en la imagen puedes observar que el átomo de carbono es el que está de color negro, los átomos de hidrógeno están de color gris y los átomos de oxígeno de color rojo.

En la reacción, 1 molécula de CH₄ reacciona con 2 moléculas de O₂ produciendo 1 molécula de CO₂ (Un átomo de carbono y dos de oxígeno) y dos moléculas de agua (H₂O, un átomo de oxígeno y dos de hidrógeno).

Así, la reacción correctamente balanceada es:

<em>a. CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(g)</em>

Answer:

CH 4 (g) + 20 2 (g)- CO 2 (g) + 2H 2 0 (g)

Explanation:

A balanced chemical reaction equation is one in which the number of atoms of each element on the reactants side is equal to the number of atoms of each element on the product side.

We can balance the equation by carrying out an atom count, that is, we count the atoms of each element on the reactant side and on the products side.

For instance;

Carbon has one atom on both sides of the reaction equation

Oxygen has four atoms on both sides of the reaction equation

Hydrogen has four atoms on both sides of the reaction equation.

Hence we can say that the reaction equation is balanced.

Answer:

\boxed{-6.29 \times10^{5}\text{ J}}

Explanation:

Step 1. Determine the cell potential

                                                  <u>    E°/V     </u>

2×[Cr ⟶ Cr³⁺ + 3e⁻]                  0.744  V

<u>3×[Cu²⁺ + 2e⁻ ⟶ Cu]             </u>   <u>0.3419 V </u>

2Cr + 3Cu²⁺ ⟶ 3Cu  + 2Cr³⁺    1.086  V

Step 2. Calculate ΔG°

\Delta G^{\circ} = -nFE_{\text{cell}}^{^{\circ}} = -6 \times 96 485 \times 1.086 = \text{-629 000 J}\\\\= \boxed{-6.29 \times10^{5}\text{ J}}

What happens to a glass of water as the average molecular kinetic energy of the water molecules increases?
trasher [3.6K]
"The water becomes warmer."
<u>Remember</u>: Kinetic energy means how much, on average, a molecule is moving around. This is directly translated into heat. Therefore, the higher the kinetic energy, the more heat produced.
