Answer:
Explanation:
Given that,
Mass of a piece of Aluminium, m = 66 grams
The density of Aluminium, d = 2.70 g/cm³
We need to find the volume of this piece in cm³.
We know that,
Density = mass per unit volume
So, the volume of the piece is .
In a endothermic reaction energy from an outside source is continuously being added.
Answer:
The answer to your question is below
Explanation:
Energy is absorbed in an exothermic reaction. An exothermic reaction releases energy so this option is wrong.
Energy is released in an endothermic reaction. This option is wrong because an endothermic reaction absorbed energy.
The products have more potential energy than the reactants in an exothermic reaction. This option is wrong because in this kind of reactions the reactants have more potential energy than the products.
The products have more potential energy than the reactants in an endothermic reaction. This option is correct, one characteristic of endothermic reactions is that the products have more potential energy than the reactants.
