Answer:
76 mmHg is the partial pressure of oxygen on this new planet.
Explanation:
Atmospheric pressure on air on earth = 760 mmHg
On an unknown planet :
Oxygen makes up 10% of the atmosphere.
The mole fraction of oxygen gas can be written as = 
Carbon dioxide makes up 15% of the atmosphere.
The mole fraction of carbon dioxide gas can be written as = 
Nitrogen makes up the remaining 75% of the atmosphere.
The mole fraction of nitrogen gas can be written as = 
Atmospheric pressure of air on unknown planet,p= 760 mmHg (given)
Partial pressure of gases can be calculated by the help o Dalton's law of partial pressure:
Partial pressure of oxygen gas :
Partial pressure of carbon dioxide gas :
Partial pressure of nitrogen gas :
<h2>Answer:</h2>
What does Atomic number represents ___________.
What does the Mass number represent ___________
Periods are _____________ rows.
Groups are _____________ columns.
Total elements in periodic table are _____________.
Zn, Cd, and Ag are transition metals that usually form only one monoatomic cation.
A monatomic cation is a cation made of only one atom.
Cations are positively charged ions, in this example Ag⁺, Cd²⁺ and Zn²⁺.
These cations form only one type of ion, while iron and copper form more than one type of cations.
Iron and copper form cations with different charges (Fe²⁺, Fe³⁺, Cu⁺, Cu²⁺).
It depends on electron configuration which type would be formed.
Electron configuration of zinc atom: ₃₀Zn 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s²
Transition metals are elements in the d-block of the Periodic table.

#SPJ4
write the equation for the reaction
that is 6 F2 +P4 =4 PF3
find the theoretical mass that is
let the theoretical yield be represented by y
theoretical yield = 78.1/100 = 120/y
y= 153.6 grams
find the number of moles of PF3
moles = mass/molar mass
= 153.6/87.97 =1.746 moles
by use of mole ratio between F2 :PF3 which is 6:4 the moles of F2 is therefore= 1.746 x 6/4 = 2.62 moles
mass = moles x molar mass
= 1.746 moles x38 g/mol = 99.6 grams
