¿Cuántos ml de alcohol contiene una lata de cerveza de 375 ml si tiene una concentración 4% v/v?

Chemistry
1 answer:
Wewaii [24]3 years ago
3 0

Answer:

15 mL

Explanation:

El valor de concentración de 4% v/v nos dice que de cada 100 mL de cerveza, 4 mL son de alcohol.

Con eso en mente podemos <u>calcular los mL de alcohol presentes en 375 mL</u>, de la siguiente forma:

  • 375 mL * 4/100 = 15 mL

En 375 mL de cerveza de concentración 4% v/v, hay 15 mL de alcohol.

In tne equation below identify the bronsted lowry acid bronsted lowry base conjugate acid conjugate base
Ad libitum [116K]

Answer:

  • <em>Brønsted-Lowry acid: HNO₂</em>
  • <em>Brønsted-Lowry base: NH₃</em>
  • <em>Conjugate acid: NH₄⁺</em>
  • <em>Conjugate base: NO₂⁻</em>

Explanation:

The equation is:

                 HNO_2(aq)+NH_3(aq)\rightarrow NH4^+(aq)  + NO2^-(aq)

<em>Brønsted-Lowry acids</em>  are H⁺ donors.

<em>Brønsted-Lowry bases</em> are H⁺ acceptors.

Thus, on the left side, <em>HNO₂</em> is the acid and <em>NH₃ </em>is the base.

The <em>conjugate acids</em> and <em>conjugate bases</em> are on the right side of the equation.

The <em>conjugate acid</em> is the spieces that is formed after a base accepts the proton; thus it is <em>NH₄⁺</em>. A <em>conjugate acid</em> contains one more H atom and one more + charge than the base that formed it.

The <em>conjugate base</em> is the species that is formed after the acid donates its proton; thus, <em>NO₂⁻</em> is the <em>conjugate base</em>. A <em>conjugate base</em> contains one less H atom and one more - charge than the acid that formed it.

Summarizing:

  • Brønsted-Lowry acid: HNO₂
  • Brønsted-Lowry base: NH₃
  • Conjugate acid: NH₄⁺
  • Conjugate base: NO₂⁻
