A candle slowly burns until the last bit of wax and wick are gone. The two reactants in this chemical reaction are the wick and
NemiM [27]

Only the oxygen part of the atmosphere participates in the burning of candle wax.

When the candle is burning, the wick burns and the heat generated from burning melts the wax. The liquid wax serves as a fuel that sustains the burning of the wick.

The candle wax is a hydrocarbon. Hydrocarbon compounds are generally known to burn is oxygen to produce carbon dioxide and water.

Thus, the candle wax burns in the oxygen component of the air to produce carbon dioxide and water as by-products. All other components of air do not participate in the system.

4. How much energy will it take to raise the temperature of 75.0 g of water from 20.0 °C to 55.0 °C?
mel-nik [20]

Answer:

1.1 x 10⁴ J

Explanation:

To calculate eth energy needed, you need to use the following equation:

Q = mcΔT

In this equation,

-----> Q = energy/heat (J)

-----> m = mass (g)

-----> c = specific heat (4.184 J/g°C)

-----> ΔT = change in temperature (°C)

You can plug the given values into the equation and solve.

Q = mcΔT

Q = (75.0 g)(4.184 J/g°C)(55.0 °C - 20.0 °C)

Q = (75.0 g)(4.184 J/g°C)(35.0)

Q = 11,000 J

Q = 1.1 x 10⁴ J

the normal boiling point of ethanol is 78.3 and its molar heat of vaporization is 393. Calculate the vapor pressure of ethanol a
madam [21]

<u>0.12 atm</u><u> </u><u>vapor pressure</u><u> of ethanol at 45.0 C.</u>

What is vapor pressure in science definition?

  • Vapour pressure is a measure of the tendency of a material to change into the gaseous or vapour state, and it increases with temperature.
  • The temperature at which the vapour pressure at the surface of a liquid becomes equal to the pressure exerted by the surroundings is called the boiling point of the liquid.

We will use the Clausius-Clapeyron equation,

ln(P2/P1) = dHvap/R[1/T1-1/T2]

where,

P1 = unknown

P2 = 1 atm

T1 = 30 oC = 30 + 273 = 303 K

T2 = 78.3 oC = 78.3 + 273 = 351.3 K

dHvap = 39.3 kJ/mol = 39300 J/mol

R = 8.314 J/K.mol

Feed values,

ln(1/P1) = 39300/8.314[1/303 - 1/351.3]

P1 = 0.12 atm

thus, the vapor pressure at 30° C is 0.12 atm.

What would be the volume, in liters measured at STP, of 0.56 moles of carbon monoxide?
sertanlavr [38]

Answer:

"This conversions relies on the fact that a mole of gas at STP has a volume of 22.4 L. It is important to note, however, that if the conditions of the gas are different this conversion will NOT work. Under those conditions you must use the ideal gas law to convert between moles and liters."
