Answer:

B. 3+

Explanation:

When Fe²⁺ loses an electron, it becomes an Fe³⁺ ion.

   The loss of an electron in an atom makes the atom becomes positively charged. Further losing electrons makes the atom more positive.

 For the given ion;

 Fe²⁺   if it loses an electron more, it becomes Fe³⁺.

The expression is given as:

         Fe²⁺    →    Fe³⁺  +  e⁻

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.

Chlorine (CI) can be found as an ion with a 1- charge. How does this happen?
Lesechka [4]

Answer:There are 18 electrons and 17 protons, so the chlorine atom has become a charged chlorine ion with a charge of negative one (-1). ... When it does, the sodium atom becomes a sodium ion with a charge of positive one (+1). Chlorine, as mentioned above, desperately wants an electron so it can fill its outer electron level.

Where do convection currents form?
pshichka [43]

Answer:

I think it's C

<u>Convection currents are identified in Earth's mantle. Heated mantle material is shown rising from deep inside the mantle, while cooler mantle material sinks, creating a convection current. It is thought that this type of current is responsible for the movements of the plates of Earth's crust.</u>

What is the equilibrium constant expression for the reaction below?<br> H2 (g) + I2 (g) → 2 HI(g)
brilliants [131]
<h3>Further explanation</h3>

Given

Reaction

H₂ (g) + I₂ (g) → 2HI(g)

Required

The equilibrium constant

Solution

The equilibrium constant is the value of the product in the equilibrium state of the substance in the right (product) divided by the substance in the left (reactant) with the exponents of each reaction coefficient

The equilibrium constant for reaction  

pA + qB ⇒ mC + nD  

\large {\boxed {\bold {K ~ = ~ \frac {[C] ^ m [D] ^ n} {[A] ^ p [B] ^ q}}}}

So for the above reaction :

\tt K=\dfrac{[HI]^2}{[H_2][I_2]}
