Answer:
In a chemical change, the atoms in the reactants rearrange themselves and bond together differently to form one or more new products with different characteristics than the reactants. When a new substance is formed, the change is called a chemical change.
Explanation:
Answer:
857mL de la solución al 7%
Explanation:
Una solución de agua oxigenada (H₂O₂) al 7% contiene 7mL de peróxido de hidrógeno por cada 100mL de solución = 7mL H₂O₂ / 100mL Sln
Para preparar un litro = 1000mL de disolución al 6% de peróxido de hidrógeno se requieren:
1000mL Sln * (6mL H₂O₂ / 100mL Sln) = 60mL H₂O₂
Para obtener 60mL de H₂O₂ a partir de la solución al 6% se requieren:
60mL H₂O₂ * (100mL Sln / 7mL H₂O₂) =
<h3>857mL de la solución al 7%</h3>
The carbonate mineral that reacts readily with hydrochloric acid that is at a low temperature and dilute is the calcite mineral. This reaction produces carbon dioxide which is manifested from the bubbles that is seen as the two substances are contacted.
Answer:
Absolutely correct
Explanation:
Displacement is vector i.e. it deals with magnitude and direction WHILE Distance is scalar i.e. it only deals with magnitude
