Answer:
Helium
Explanation: The ionization energy decreases from the top to bottom in groups. And increases from left to the right across a period. Therefor Helium has tge largest first ionization energy, while francium has one of the lowest.
Answer:C) 96 j
explanation:48 N * 2.0 m = 96. Your answer should be C, 96 joules.
Answer: 0.209 M
Explanation:
Moles of = 2.00 mole
Moles of = 1.50 mole
Volume of container = 5.00 L
Initial concentration of =
Initial concentration of =
The given balanced equilibrium reaction is,
Initial conc. 0.400 M 0.300M 0 M 0 M
At eqm. conc. (0.400-x) M (0.300-x) M (x) M (x) M
The expression for equilibrium constant for this reaction will be,
Now put all the given values in this expression, we get :
By solving the term 'x', we get :
x = 0.209 M
Concentration of at equilibrium = x M = 0.209 M
The amount of energy required to eat 5.25 g of Titanium from 85.5 celsius to 132.5 celsius is 129 joules.
<h3>
How do we calculate required heat?</h3>
Absorbed or released amount of heat will be calculated by using the below formula as:
Q = mcΔT, where
m = mass of titanium = 5.25g
c = specific heat of titanium = 0.523 J/gram degree celsius
ΔT = change in temperature = 132.5 - 85.5 = 47 degree celsius
On putting these values on the above equation we get,
Q = (5.25)(0.523)(47) = 129 joules
Hence required heat is 129 joules.
