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.
Combustion reaction because it produces water and carbon dioxide
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.
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
Answer:
Explanation:
Area of a circular hubcap is 615 square inches
Area of a circular shaped object is given by :
r is radius of hubcap.
If the radius of the hubcap were quadrupled, it means r' = 4r. New area will become:
A' is new area
New area of the hubcap is 9840 square inches.
