grin007 [14]
Answer:

D


Explanation:


At constant volume, the heat of reaction is equal to the change in the internal energy of the system. ... Most chemical reactions occur at constant pressure, so enthalpy is more often used to measure heats of reaction than internal energy.

____ [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>

A 100 W light bulb is placed in a cylinder equipped with a moveable piston. The light bulb is turned on for 2.0×10−2 hour, and t
drek231 [11]

Answer:

(a) ΔU = 7.2x10²

(b) W = -5.1x10²

(c) q = 5.2x10²

Explanation:

From the definition of power (p), we have:

p = \frac {\Delta W}{\Delta t} = \frac {\Delta U}{\Delta t} (1)

<em>where, p: is power (J/s = W (watt)) W: is work = ΔU (J) and t: is time (s) </em>  

(a) We can calculate the energy (ΔU) using equation (1):

\Delta U = p \cdot \Delta t = 100 \frac{J}{s} \cdot 2.0\cdot 10^{-2} h \cdot \frac{3600s}{1h} = 7.2 \cdot 10^{2} J  

(b) The work is related to pressure and volume by:

\Delta W = -p \Delta V

<em>where p: pressure and ΔV: change in volume = V final - V initial      </em>

\Delta W = - p \cdot (V_{fin} - V_{ini}) = - 1.0 atm (5.88L - 0.85L) = - 5.03 L \cdot atm \cdot \frac{101.33J}{1 L\cdot atm} = -5.1 \cdot 10^{2} J

(c) By the definition of Energy, we can calculate q:

\Delta U = \Delta W + \Delta q

<em>where Δq: is the heat transfer </em>

\Delta q = \Delta U - \Delta W = 7.2 J - (-5.1 \cdot 10^{2} J) = 5.2 \cdot 10^{2} J    

I hope it helps you!
