You're wrong because the third energy level can contain 18 <span>electrons. And the 4th have up to 32 elections.

The pattern go by 2-8-18-32</span>

For the reaction a2 + b2 → 2ab, ea(fwd) = 105 kj/mol and ea(rev) = 77 kj/mol. assuming the reaction occurs in one step, calculat
Lady bird [3.3K]
Answer is: 28 kJ.
Chemical reaction: A₂ + B₂ ⇄ 2AB.
Ea(forward) = 105 kJ/mol.
Ea(reverse) = 77 kJ/mol.
ΔH(reaction) = ?
<span>The enthalpy change of reaction is the change in the energy of the reactants to the products.
</span>ΔH(reaction) = Ea(forward) - Ea(reverse).
ΔH(reaction) = 105 kJ/mol - 77 kJ/mol.
ΔH(reaction) = 28 kJ/mol; this is endothermic reaction (ΔH <span>> 0).</span>

Which of the following is true regarding nuclear fission and nuclear fusion?
Zarrin [17]
<h2>Nuclear Fission and Nuclear Fusion - Option C</h2>

Nuclear fission and nuclear fusion both of these processes can provide energy. Nuclear fission is the process in which heavy nucleus splits into smaller parts. When they split into smaller particles then it releases energy.

On the other hand, nuclear fusion is the process in which small particles fuse together to form a heavy nucleus. With the formation of heavy nucleus, it also provides energy.

Therefore, both these processes release or provide energy.

Necesito ayuda 3.- Anota las características que correspondan a cada tipo de hibridación. Tipo de hibridación, Arreglo geométric
ololo11 [35]

Answer:

ver explicacion

Explanation:

Los orbitales híbridos se obtienen mediante una combinación de orbitales atómicos.

En un átomo de carbono con hibridación sp3, el átomo de carbono es tetraédrico con un ángulo de enlace de 109,5 grados. Se pueden unir cuatro enlaces simples al átomo de carbono. Se pueden unir un total de cuatro átomos al carbono. Se puede unir un total de cuatro átomos al carbono, lo que ocurre en alcanos como el metano

Para un átomo de carbono con hibridación sp2, hay dos enlaces dobles y dos enlaces simples unidos al átomo de carbono que tiene una geometría plana trigonal con un ángulo de enlace de 120 grados. Se pueden unir un total de dos átomos al carbono. Se pueden unir un total de dos átomos al carbono. Esto ocurre en alquenos como el eteno.

Un átomo de carbono con hibridación sp tiene un ángulo de enlace de 180 grados y tiene una geometría lineal con un enlace triple y un enlace sencillo. Solo se puede unir un átomo al carbono. Esto ocurre en alquinos como el etino.
