A) Double replacement
Because the reactants switch when they become products
I believe it is a(n) independent variable
i could be wrong sorry<span />
Answer:
2,2,3- trimethylhexane because it has more carbon atoms than pentane.
Explanation:
Hello.
In this case, since the physical properties of organic compounds are intensified as the number of carbon atoms start increasing on it, the larger the amount of carbon atom, the higher the boiling point since more energy is required to allow the liquid-phase molecules to transcend to the vapor-phase.
In such a way, since pentane has five carbon atoms and 2,2,3- trimethylhexane has nine carbon atoms, 2,2,3- trimethylhexane has the highest boiling point.
Best regards.
Answer : The correct option is, (A) 0.42 moles
Explanation :
Using ideal gas equation:
where,
P = pressure of gas = 125000 Pa = 125 kPa
conversion used : (1 kPa = 1000 Pa)
V = volume of gas =
conversion used :
T = temperature of gas = 357 K
n = number of moles of gaseous mixture = ?
R = gas constant = 8.314 kPa.L/mol.K
Now put all the given values in the ideal gas equation, we get:
Therefore, the number of moles of an ideal gas is 0.42 mole.
The water cycle deals with wind. The wind uses up energy as well as the water cycle.
