<span>An exothermic reaction is one in which there is the production of heat whereas an endothermic reaction is one in which heat is absorbed. For the choices above, the answer would be letter B. Ice melting in water and an ice pack turning cold absorbs heat which is why it is an endothermic reaction. Exploding fireworks and gasoline burning gives off heat which is why it is an exothermic reaction.</span>
Answer:
Respiración anaerobica
Explicación:
Las nuevas especies carecen de mitocondrias, por lo que realizan respiración anaeróbica porque en las mitocondrias solo ocurre la respiración aeróbica mientras que la respiración anaeróbica ocurre en el citoplasma de la célula. Trabajar en armonía es muy importante para el funcionamiento normal de su cuerpo. Por ejemplo, el funcionamiento combinado del sistema circulatorio y excretor. ambos sistemas hacen su trabajo mutuamente y por eso hay armonía en el cuerpo.
Answer:
<h2>0.5 moles</h2>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
We have the final answer as
<h3>0.5 moles</h3>
Hope this helps you
Answer is: <span>the spectator ions in the this reaction is K</span>⁺ and SO₄²⁻.<span>
Chemical reaction: </span>2KOH(aq) + H₂SO₄(aq) → 2H₂O(l) + K₂SO₄<span>(aq).
Ionic reaction: 2K</span>⁺ + 2OH⁻ + 2H⁺ + SO₄²⁻ → 2H₂O + 2K⁺ + SO₄²⁻.
Net ionic reaction: 2OH⁻ + 2H⁺ → 2H₂O.
A spectator
ion is
an ion that exists as a reactant and a product in a chemical equation.
