____ [38]

Answer:

La afirmación es verdadera.

Explanation:

El método científico es un método de  investigación usado principalmente en la producción de conocimiento en las ciencias y se define como un procedimiento para tratar un conjunto de problemas. En ciencia, el método científico es la estrategia para la investigación y la exploración de lo desconocido.

Por lo que el método científico es el procedimiento mediante el cual es posible alcanzar un  conocimiento objetivo de la realidad, tratando de dar respuesta a las interrogantes  acerca del orden de la naturaleza.

Para ser científico, un método de investigación debe basarse en la empírica y en la  medición, sujeto a los principios específicos de las pruebas de razonamiento.

El método científico se basa en la reproducibilidad, es decir, la  capacidad de repetir un determinado experimento, en cualquier lugar y por cualquier  persona, y la refutabilidad,  es  decir toda proposición científica tiene que ser susceptible de  ser falsada o refutada.

Entonces <u><em>la afirmación es verdadera.</em></u>

Two species of frog mate in the same pond. One breeds in early summer and one in late summer. This is an example of what kind of
MatroZZZ [7]

Answer:

Pre-zygotic, temporal separation

Explanation:

Reproductive isolation mechanism is of two types:

  • Prezygotic mechanism
  • Postzygotic mechanism

Prezygotic mechanism isolation occurs before fertilization and helpful in preventing formation of fertile offspring.

In frog external fertilization occurs. In the external fertilization, eggs and sperms are released in water and fertilization occur outside the water.

Prezygotic isolating mechanisms may include behavioral isolation, temporal isolation, mechanical isolation, gametic isolation and habitat isolation.

Temporal separation in reproduction is the sexual activity in the same geographical range but in different periods.

Therefore, the given reproductive isolation is pre-zygotic, temporal separation.

Hydrogen sulfide,H2S, is a very toxic gas with a smell of rotten eggs. using the following: H2S+3/2 O2=SO2+H2O H2+1/2O2=H2O S+O2
Serga [27]

Answer:

ΔH = -20kJ

Explanation:

The enthalpy of formation of a compound is defined as the change of enthalpy during the formation of 1 mole of the substance from its constituent elements. For H₂S(g) the reaction that describes this process is:

H₂(g) + S(g) → H₂S(g)

Using Hess's law, it is possible to sum the enthalpies of several reactions to obtain the change in enthalpy of a particular reaction thus:

<em>(1) </em>H₂S(g) + ³/₂O₂(g) → SO₂(g) + H₂O(g) ΔH = -519 kJ

<em>(2) </em>H₂(g) + ¹/₂O₂(g) → H₂O(g) ΔH = -242 kJ

<em>(3) </em>S(g) + O₂(g) → SO₂(g) ΔH = -297 kJ

The sum of -(1) + (2) + (3) gives:

<em>-(1) </em>SO₂(g) + H₂O(g) → H₂S(g) + ³/₂O₂(g) ΔH = +519 kJ

<em>(2) </em>H₂(g) + ¹/₂O₂(g) → H₂O(g) ΔH = -242 kJ

<em>(3) </em>S(g) + O₂(g) → SO₂(g) ΔH = -297 kJ

<em>-(1) + (2) + (3): </em><em>H₂(g) + S(g) → H₂S(g) </em>

<em>ΔH =</em> +519kJ - 242kJ - 297kJ = <em>-20 kJ</em>

<em />

I hope it helps!
