from supernova explosion....
Here I will write you a wonderful video about with beautiful animations...
if you find my answer helpful and my citation is good...please make it brainliest.
watch?v=e-P5IFTqB98
google this and...watch the first video...its from channel called kurzgesagt...very beautiful channel.
The choices can be found elsewhere and as follows:
A)The reaction requires the collision of three particles with the correct energy and orientation.
<span>B) All reactions that occur in one step are slow. </span>
<span>C)The probability of an effective three-particle collision is low. </span>
<span>D) The transition state is low in energy.
</span>
I think the correct answer from the choices listed above is option C. If the uncatalyzed reaction occurs in a single elementary step, it is a slow reaction because the probability of an effective three-particle collision is low.
Answer:
C. 12.8 liters.
Explanation:
The Standard Temperature and Pressure (STP) of a gas are 273.15 K and 100 kilopascals. From Avogadro's Law, a mole of carbon dioxide contains
molecules. If we suppose that carbon dioxide behaves ideally, then the equation of state for ideal gas is:
(1)
(1b)
Where:
- Pressure, measured in pascals.
- Volume, measured in liters.
- Amount of molecules, no unit.
- Avogadro's number, no unit.
- Ideal gas constant, measured in pascal-liters per mole-Kelvin.
- Temperature, measured in Kelvin.
If we know that
,
,
,
and
, then the volume of carbon dioxide at STP is:



Therefore, the correct answer is C.
Answer:
.........................okay?
<span>The combined gas equation relates three variables pressure, temperature and volume when the number of moles is constant.
The equation is PV / T = constant. Which is valid for a fixed number of moles of the gas.
You can derive the combined gas equation from the combination of Bolye's law, Charles' law and Gay-Lussac's law, which needs some algebra.
Answer: option 2. number of moles.
