Answer:

DICLORURO DE ZINC

Explanation:

La ecuación es:

Zn (s) + 2HCl (aq)  →  ZnCl₂ (aq) +H₂ (g)

El zinc reacciona en una reacción redox con el acido clorhídrico para formar una sal y liberar el hidrogeno gaseoso.

Se trata de una reacción redox porque el hidrógeno se reduce (disminuye el numero de oxidación, de -1 a 0, en su estado fundamental), mientras que el Zn se oxida (el numero de oxidación aumenta de 0 a +2).

Como la sal se forma con dos atomos de cloro, se denomina dicloruro por lo que el nombre correcto de la sal en nomenclatura sistemática es:

- DICLORURO DE ZINC

What is the molar ratio for the following equation after it has been properly balanced?
slava [35]
The answer 
<span>the molar ratio for the following equation 
____C3H8 + ____O2 Imported Asset ____CO2 + ____ H2O

</span>after it has been properly balanced:
__1_C3H8 + ____5O2 Imported Asset ____3CO2 + ____ 4H2O

proof:
number of C =3  (C3H8;   3CO2)
number of H =8 (C3H8 ; 4H2O)
number of O = 10(5x2) or (2x3+4)  (5O2;4H2O)

the answer is 
<span>Reactants: C3H8 = 1, O2 = 8; Products: CO2 = 3 and H2O = 4</span>

What two molecules were condensed in an aldol condensation to produce (ch3)3cch=chcoch3?
inessss [21]
The given compound is being synthesized by condensing Acetone and Pivaldehyde (Trimethylacetaldehyde).

First Acetone is treated with Base, the base abstracts the mildly acidic proton present at alpha position to carbonyl group. The resulting specie called enolate act as a nucleophile and attacks on highly reactive aldehyde which upon dehydration yields the Aldol Product. The Reaction is as follow,
