One of the many ways in order to solve for the vapor pressure of pure components at a given temperature is through the Antoine's equation which is written below,
P = 10^(A - B/C+T)
where A, B, and C are constants and T is the temperature in °C and P is the vapor pressure in mm Hg.
For hexane,
A = 7.01
B = 1246.33
C = 232.988
Substituting the known values,
P = 10^(7.01 - 1246.33/232.988+25)
<em> P = 151.199 mm Hg</em>
Answer:
Ca(OH)₂ + 2HCl → CaCl₂ + 2H₂O
Explanation:
Reactants;
Calcium hydroxide = Ca(OH)₂
Hydrogen chloride = HCl
Products;
Calcium chloride = CaCl₂
Water = H₂O
The reaction equation:
Ca(OH)₂ + 2HCl → CaCl₂ + 2H₂O
The reaction is a neutralization reaction where acids reacts with bases to produce salt and water only.
I think this is true because they’re in the same layer, strata which would mean they died around the same time. Hope this helps sorry if it’s wrong!
6 grams of Carbon is it’s mass
<u>Explanation:</u>
First we have to divide the given number of atoms 
by the Avogadro's number 
, so that we will get the number of moles as 1/2.
Then the 1/2 moles of carbon is multiplied by the molar mass of Carbon which is 12 g/mol, we will get the mass of carbon as 6 grams.
So the mass of the carbon obtained is 6 grams.
