Answer: The gas occupies a space of 5.57 L at 26 Celsius and 101.75 kPa.
Explanation:
Given: Mass = 26 g
Pressure = 101.75 kPa
Convert kPa into atm as follows.
Temperature =
Now, moles of a substance is defined as mass of substance divided by its molar mass.
As molar mass of 2,2 dimethyl hexane is 114.23 g/mol. So, its number of moles are calculated as follows.
Formula used to calculate the volume is as follows.
PV = nRT
where,
P = pressure
V = volume
n = no. of moles
R = gas constant = 0.0821 L atm/mol K
T = temperature
Substitute the values into above formula as follows.
Thus, we can conclude that the gas occupies a space of 5.57 L at 26 Celsius and 101.75 kPa.
The answer is none of the above. If you look at the reaction results, you'll notice that one of the products make are K2O. Because of this ratio, it's essentially impossible to balance this equation.
The type of chemical reaction is decomposition, as the compound is being broken down into other smaller compounds.
Answer: initial temp of metal= 100 C
initial temp of water= 22.6 C
Final temp of both= 23.3 C

Well, this is obviously an opinion question, so share your opinion. If you are happy that the Agricultural Revolution(s) paved way for the earth to sustain billions of people, then that's great. But, if you wish there were fewer people on the planet, then share that. Of course, both sides have their pros and cons. Just share your opinion. Good luck!
