50/35 = √x/ √31.9988 g
50 x (√31.9988/ 35) = √x

√x = 8.081...

x= 65.30...

x= 70 g/ mol

The disturbance of a supersaturated solution will cause
Flura [38]
The disturbance of a supersaturated solution will cause precipitation. A supersaturated solution is a solution that contains more solute than the solvent can dissolve. When this type of solution is disturbed like when it is moved, the formation of a solid is observed immediately.

I’m not sure how to do this, please help. It’s a mole to mole stoich worksheet.
wlad13 [49]

Answer: 4.05 mol O2, 15.36 mol H2O

Explanation:

I can answer each question individually if you post them individually.

2a. 3.24 mol NH3 * (5 mol O2 / 4 mol NH3) = 4.05 mol O2

2b. 12.8 mol O2 ( 6mol H2O/ 5 mol O2) = 15.36 mol H2O

Essentially what I did was dimensional analysis. Multiplying in a way that the units cancel out so the only thing remains is what each question asks for.

Al colocar unos trocitos de zinc en un tubo de ensayo, agregamos 2 mL de acido clorhídrico. El Zinc sustituye el hidrogeno del a
Rudik [331]

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

Question 6
Hoochie [10]

Answer:

Explanation:

Area of a circular hubcap is 615 square inches

Area of a circular shaped object is given by :

A=\pi r^2

r is radius of hubcap.

If the radius of the hubcap were quadrupled, it means r' = 4r. New area will become:

\dfrac{A}{A'}=\dfrac{r^2}{r'^2}

A' is new area

A'=A\times \dfrac{r'^2}{r^2}\\\\A'=615\times \dfrac{(4r)^2}{r^2}\\\\A'=615\times 16\\\\A'=9840\ \text{inches}^2

New area of the hubcap is 9840 square inches.
