Explanation:
Change in the concentration of reactant that is consumed in per unit time is known as rate of reaction.
The given chemical reaction will be written as follows.
Hence, rate law for the given reaction will be as follows.
Rate = k
where, k = rate constant
= initial pressure of the pollutant X
It is given that, = initial partial pressure of X = 0.473 atm
= final partial pressure of X = 0.376 atm
Time = 5.6 hours
Hence, formula for rate constant of first order reaction is as follows.
k =
=
= 0.041 per hour
Therefore, rate of decomposition will be calculated as follows.
Rate = = k
=
=
Thus, we can conclude that initial rate of decomposition of X is .
Answer:
Your hypothesis is incorrect because warm substances rise when in a colder environment. The correct hypothesis would be : "If the 2 chambers of water are poured side by side, the warmer water will float above the cooler layer because warm water rises and cold water sinks."
Explanation:
<span>No, the only places that free electrons can exist is in plasma, electrons unbind from their original atoms and bounce around. In the core of the sun, where nuclear fusion occurs, all electrons are unbound from their atoms.</span>
I’m not quite sure but it’d probably be solar panels
Answer : The heat released by the combustion of 1.121 mol of hexane (kJ) is,
Explanation :
The given balanced reaction is,
Given:
Moles of hexane = 0.121 mol
= -8326 kJ/mol
The negative sign indicate that the reaction exothermic or amount of heat released.
As, 1 mole of hexane released heat = 8326 kJ
So, 0.121 mole of hexane released heat = 8326 × 0.121 = 1007.446 ≈
Therefore, the heat released by the combustion of 1.121 mol of hexane is .
