vessel a contains co(g) at 0 oc and 1 atm. vessel b contains so2(g) at 20 oc and 0.5 atm. the two vessels have same volume. a. which vessel contains more molecules? b. which contains more mass? c. in which vessel is the average kinetic energy of molecules higher? d. in which vessel is the rms speed of molecules higher?
Vessel B has more mass. Explanation: Because temperature and average kinetic energy of molecules are directly proportional to each other.
The average kinetic energy of a substance's particles is directly inversely correlated with its temperature. As the temperature increases, the particles must travel more quickly because their mass remains constant.
The relationship between a gas particle's average kinetic energy and temperature is linear. The pace at which the gas molecules flow rises with temperature. At a specific temperature, the average kinetic energy of all gases is identical.
Molecules of gas move more quickly when they are lighter. Because of this, as the gas's temperature rises, its volume also does so. The more gas particles there are, the more likely it is that they will hit the container's walls, hence the frequency of collisions must rise.

How much heat, in joules, does it take to raise the temperature of 225. 0 g of water from 25. 0°c to 100. 0°c ?.
The amount of heat required to raise the temperature of 225.0 g of water from 25.0°C to 100.0°C is equal to 67,837 joules.
What is temperature?
A physical quantity known as temperature expresses the concepts of hotness as well as coldness in numerical form. With a thermometer, temperature is measured. Thermometers are calibrated using a number of temperature scales which historically defined various reference points as well as thermometric substances. The most widely used scales are the Kelvin scale (K), which is primarily used for scientific purposes, the Fahrenheit scale (°F), as well as the Celsius scale (°C), formerly known as centigrade, with the unit symbol °C. In the Worldwide System of Units, one of the eight base units is the kelvin (SI).
The amount of heat, in joules, required to raise the temperature of 225.0 g of water from 25.0°C to 100.0°C can be calculated using the equation:
Q = mcΔT
where
Q = heat in joules,
m = mass of the water in grams,
c = specific heat capacity of water,
ΔT = change in temperature (100.0°C – 25.0°C = 75.0°C).
Using these values, the equation can be rearranged to:
Q = (225.0 g) (4.184 J/g°C) (75.0°C)

How many moles of chlorine gas can be produced if 4 moles of fecl3 react with 4 moles of o2.
6 moles of chlorine gas can be produced if 4 moles of fecl3 react with 4 moles of o2.
FeCl3+O2-->Fe2O3+Cl2 is not balanced.
We first need to balance the equation. The balanced equation:
4FeCl3 + 3O2 ==> 2Fe2O3 + 6Cl2
moles FeCl3 present =4 moles
moles O2 present = 4 moles
Since the mole ration in the balanced equation is 4 FeCl3 : 3 O2, the limiting reactant will be FeCl3.
So, moles Cl2 that can be produced = 4 moles FeCl3 x 6Cl2/4 moles FeCl3 = 6 moles Cl2.

Which of the following is true of real machines?
The statement that is correct about real machines is that work output is less then work input. So the correct option is A.
Why the statement is correct?This is correct because in a real machine the production of work will never be greater than the input it has of work, since the machines themselves will lose energy in some way during the formation of the production of work. When losing energy, then, there will be less production and material than there was at the beginning of production.
This is quite the opposite in an ideal machine, where all the work that will be put in becomes the work output. It changes because in the ideal situation it does not take into account various variables that occur in reality that can cause energy to be lost in the process.

Helium, neon, argon, krypton, xenon, and radioactive radon are the six types of noble gases that are found in nature. Noble gases have entirely filled outer electron shells, are most frequently encountered as monatomic gases, and have no tendency to combine with other elements. As a result, they extremely infrequently form compounds with other elements. But it is conceivable to cause a noble gas to respond, just as one might force a nobleman to lose his honor.
