The specific heat of water and steam (water vapor) are 4.18
J/gºC and 2.10 J/gºC respectively. Heating a 74.0 g sample of
water from 88.3 °C to water vapor at 112.5 °C requires 172.58 kJ
of heat. Calculate the heat of vaporization of water in kJ/g.
Assume the boiling point of water is 100 °C.

please help

Answers

Answer: 2.26

Explanation:

The heat of the vaporization of water is equal to 2.33 KJ/g.

What is the specific heat capacity?

The specific heat capacity can be explained as the quantity of heat required to raise the temperature in one unit of substance by 1 degree Celcius.

The specific heat can be represented in terms of gained or lost heat:

Q = mCΔT

The heat of vaporization can be described as the amount of heat required to turn one gram of a liquid into a vapor, without an increase in the temperature of the liquid.

Given, the amount of heat gained by water, Q =  172.58 kJ

The change in the temperature = 112.5 - 88.3 = 24.2 °C

The specific heat capacity of the water = 4.184 J/g°C

The mass of the water, m = 74 g

The heat of vaporization of water H = q/m

H = 172.58/74

H = 2.33 KJ/g

Therefore,  the heat of the vaporization of water is equal to 2.33 KJ/g.

A 800 kg car zooms away from a red light with an acceleration of 7.6 m/s2. What is the
average net force in Newtons that the car experiences?

Answers

Answer:

6080 N

Explanation:

From the question given above, the following data were obtained:

Mass (m) of car = 800 Kg

Acceleration (a) of car = 7.6 m/s²

Force (F) =?

The force experienced by the car can be obtained as illustrated below:

Force (F) = mass (m) × acceleration (a)

F = m × a

F = 800 × 7.6

F = 6080 N

Thus, the experience a force of 6080 N

Answers

Answer:

DICLORURO DE ZINC

Explanation:

La ecuación es:

Zn (s) + 2HCl (aq)  →  ZnCl₂ (aq) +H₂ (g)

El zinc reacciona en una reacción redox con el acido clorhídrico para formar una sal y liberar el hidrogeno gaseoso.

Se trata de una reacción redox porque el hidrógeno se reduce (disminuye el numero de oxidación, de -1 a 0, en su estado fundamental), mientras que el Zn se oxida (el numero de oxidación aumenta de 0 a +2).

Como la sal se forma con dos atomos de cloro, se denomina dicloruro por lo que el nombre correcto de la sal en nomenclatura sistemática es:

- DICLORURO DE ZINC

A gas sample is made entirely of carbon dioxide and water, and there are 300 moles of CO2 and 500 moles of H2O. If the total pressure of the sample is 21 atm, what is the partial pressure of H2O ? Ptotal = Pa + Pb+ Pc....... Pa = Xa(Ptotal)

Answers

Answer:

Explanation:

Total moles = 300 + 500 = 800 moles

mole fraction of carbon dioxide = 300 / 800 = 3 / 8

water = 500 / 800 = 5 / 8

Total pressure = 21 atm

partial pressure of water = total pressure x mole fraction of water

= 21 x 5 / 8

= 13.125 atm

C. Less lift is created because there are fewer air molecules.
O D. There is not enough thrust to propel the airplane past the sound
waves.

Answers

Answer:

More drag is created because the air molecules are not moving out of the way of the airplane. This is 100% correct, just did the test

Explanation: a pe x

The faster an object vibrates, the higher is the frequency and higher will be the pitch of the sound. During a flight approaching the speed of sound More drag is created because the air molecules are not moving out of the way of the airplane. The correct option is A.

What is sound?

The sound is defined as a vibration which propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid. The speed of a sound wave is affected by the medium through which it travels. Sound travels fastest in solids.

In aerodynamics, drag refers to the forces that oppose the relative motion of an object through the air. Drag always opposes the motion of the object and in an aircraft is overcome by thrust. Drag is a rearward force caused by the disruption of airflow by wing.

So here when a flight is approaching the speed of sound more drag is created.

Thus the correct option is A.
