Answer:
I have no clue at all im in 11 and dont know anything lol byeeee
Explanation:um um i am lost
We need more explanation, there is no picture or text.
31.5. If Δ<em>G</em>° = -8.550 kJ·mol^(1) at 25 °C, <em>K</em> = 31.5.
The relationship between Δ<em>G</em>° and <em>K</em> is
Δ<em>G</em>° = -<em>RT</em>ln<em>K</em>
where
<em>R</em> =the gas constant = 8.314 J·K^(-1)mol^(-1)
<em>T</em> is the Kelvin temperature
Thus,
ln<em>K</em> = -Δ<em>G</em>°/(<em>RT</em>)
In this problem,
<em>T</em> = (25 + 273.15) K = 298.15 K#
∴ ln<em>K</em> = -[-8550 J·mol^(-1)]/[8.314 J·K^(-1)mol^(-1) x 298.15 K]
= [8550 J·mol^(1)]/[2479 J·mol^(-1)] = 3.449
<em>K</em> = e^3.449 = 31.5
Either air pressure or gravity. I would say its gravity because of the force of two object attracting each other.
Strontium element has a mass number of 88 and contains 50 neutrons in the atom.
Given that;
Mass number of element X = 88
Number of Neutrons in element X = 50
we know the concept that Mass number is represent as total number of Neutrons and proton present in Nucleus
So, Mass number of element X = Number of Neutrons in element X + Number of Protons in element X
Thus, 88 = 50 + Number of Protons in element X
Number of Protons in element X = 38
As, Number of proton = Atomic number
So, Atomic number of element X = 38
Hence Unknown Element X is Strontium
