The average kinetic energy of an ideal gas is calculated as
KE_avg = 3/2 kT
where T is the temperature in Kelvin and k=R/N_A; R is the universal gas constant and N_A is the number of moles.
Thus, upon substitution we get
KE_avg = 3/2(8.314/1)(100+273)
KE_avg = 3/2(8.314)(373)
KE_avg = 4651.683
The average kinetic energy of 1 mole of a gas at 100 degree Celsius is 4651.683 J.
Answer:
The correct answer is - a. Fluorine is the leaving group in Sarin.
Explanation:
A leaving group is a group that leaves a complete negative charge in heterolytic cleavage when it separates out from the molecule. Sarine reacts with the active site of the enzyme acetylcholinesterase that is essential for nerve transmission.
In this given case, Sarin that is an acid fluoride and ester of methyl phosphonic acid, the fluorine atom is present is the one that leaves with a complete negative charge, therefore, fluorine is the leaving group in Sarin.
Thus, the first option is correct that Fluorine is the leaving group in Sarin.
B is the answer. For an equation to be balanced there must be the same amount of each element on the two sides. The only one where this is the case is B.
Answer:
Wind between 39-46 mph can cause branches and limbs to break, make it hard for cars to stay on the road wind between 47-54 can cause lighting difficulties, wind between the 60-78 can cause trees to uproot and damage.
Explanation:
Answer:
= 2113.44 kJ
Explanation:
When 1 mole of CH4 (g) burns in excess oxygen -714.0 kJ of heat is released.
For 47.50 g;
molar mass of CH4 = 16.042 g/mol
Number of moles of CH4
= 47.5 g /16.042 g/mol
= 2.96 moles
Therefore;
1 mole = -714.0 kJ
Heat change for 2.96 moles
= 2.96 moles × -714.0 kJ
= 2113.44 kJ
