Gene - determines the trait (phenotype)
Answer:
The vapor pressure of ethanol in the solution is 10,27 kPa
Explanation:
To obtain the vapor pressure of a solution it is necessary to use Raoult's law:
<em>(1)</em>
The moles of ethanol are:
18,00mL×
×
= 0,3083 mol Ethanol.
Moles of benzoic acid:
12,55 g×
= 0,1028 mol benzoic acid.
Thus, mole fraction of solvent, X, is:
=<em> 0,7499</em>
Replacing this value in (1):
= <em>10,27 kPa</em>
<em></em>
I hope it helps!
Answer:
2100 kPa
Explanation:
The temperature is constant, so the only variables are pressure and volume.
We can use Boyle’s Law.
p₁V₁ = p₂V₂ Divide both sides of the equation by V₂
p₂ = p₁ × V₁/V₂
p₁ = 485 kPa; V₁ = 648 mL
p₂ = ?; V₂ = 0.15 L = 150 mL Calculate p₂
p₂ = 485 × 648/150
p₂ = 2100 kPa
The term that is being described above is what we call IMMISCIBLE. This means when liquids are immiscible, it cannot be mixed in order to make a homogeneous mixture. When two liquids are mixed, these will eventually form layers. The answer to this is the first option. Hope this helps.
1840 times lesser than
Explanation:
Robert A. Milikan from his experiment found that electrons carry exactly one unit of negative charge and that its mass is 1840 times lesser than the mass of a common hydrogen atom.
- Robert Milikan performed the oil drop experiment and was able to determine the charge on an electron.
- From Milikan's experiment, the relative mass of an electron was discovered to be about 1840 times lesser than the mass of a hydrogen atom.
- A normal hydrogen atom is a proton with an actual mass of 1.67 x 10⁻²⁷kg.
- Electrons weight 9.11 x 10⁻³¹kg which is 1840 less than the weight of a proton.
