Answer:
XeF₂
Explanation:
Let's call the compound as XeaFb, where a and b are the number of atoms of each element. In the beginning, the partial pressure of XeaFb was 16 torr. By Dalton's Law, the total pressure of a gas mixture is the sum of the partial pressures of the components, so:
pH₂ = 64 - 16 = 48 torr
The reaction that happened was:
XeaFb + (b/2)H₂ → aXe + bHF
The stoichiometry of the reaction is 1:b/2:a:b. If all the XeaFb reacts:
1 torr of XeaFb -------- b/2 torr of H₂
16 torr -------- x
By a simple direct three rule:
x = 16b/2 = 8b torr of H₂ reacts
1 torr of XeaFb -------- a torr of Xe
16 torr -------- x
x = 16a torr of Xe is formed
Thus, 8b + 16a = 32
b + 2a = 4
The empirical formula is the minimum integer number of the elements in the compound. So, let's suppose a = 1 because fluorine can do only one bond, thus it's unprovable that will be more than one Xe bonded with one F:
b + 2*1 = 4
b = 2
Thus, the empirical formula is XeF₂.
The total pressure 1566 mm Hg.
Pressure is the force applied perpendicular to the floor of an object per unit location over which that pressure is shipped. Gauge strain additionally spelled gage pressure is the pressure relative to the ambient stress. pressure.
The SI unit of stress is pascal which is identical to one newton in keeping with rectangular meter. apparently, this name was given in 1971. earlier than that pressure in SI became measured in newtons in line with square meter.
Partial pressure of Argon = 429 mm Hg
Partial pressure of Neon = 1.2 atm
∵ 1 atm = 760 mm Hg
=> 1.2 atm = 1.2 * 760 mm Hg
= 912 mm Hg
Partial presser of He = 225 mm Hg
S0, Total pressure = Par + P ne + P he
= ( 429 + 912 + 225 ) mm Hg
= 1566 mm Hg

Answer:
Answer in explanation
Explanation:
An atom of iron having an atomic number of 26 means there are 26 protons in the nucleus of the iron atom. This also means that for an electrically neutral atom of iron, there are 26 electrons orbiting the nucleus of the iron atom.
Factually, this also means that the atom iron occupies the position of the 26th element on the periodic table. Going forward, we can also say that the proton number of the iron element is 26.
Liquid because it can move around with ease.
