To answer this question, we will use the following equation:
<span>ln(P2/P1) = (∆Hvap/R)*((1/T1) - (1/T2))
</span>
Now we examine the givens of the problem and transform to standard units if required:
<span>∆Hvap = 30.5 kJ/mol
</span>R is a constant = <span>8.314 x 10^-3 kJ K^-1 mol^-1
T1 </span><span>= 91 celcius = 91 + 273= 364 Kelvin
</span>T2 = 20 celcius = 20 + 273 = 293 k3lvin
P1 is the standard atmospheric pressure = 760 mmHg
P2 is the value to be calculated
Substitute with these values in the equation:
ln(P2/760) = (30.5 / 8.314 x 10^-3) x ((1 / 364) - (1 / 293))
ln(P2/760) = - 2.4662 (Take the exponential both sides to eliminate the ln)
P2 / 760 = e^(-2.4462) = 0.0866
P2 = 0.0866 x 760 = 65.816 mmHg
Answer:
1. Wildlife
2. Seafood
Explanation:
1. Wildlife refers to the species which are not domesticated by the humans and they live as a wild organisms in the areas which are not interfered with the humans. In the given question, the wild creatures that live on the land therefore are considered a part of the wildlife.
2. Seafood refers to the species which are considered as food which humans get from the sea. In the given question, the Blue Fin fishes are considered a seafood therefore.
Answer:
Phosphorylation
Explanation:
Phosphorylation is the term used to describe the transfer of a phosphate group (PO34-) from a donor to a receptor molecule or compound. The process of phosphorylation is usually catalysed by a biological enzyme called KINASE.
Phosphorylation can either be addition of an inorganic phosphate to a molecule. For example, addition of phosphate group to ADP to form ATP, or the donation of a phosphate group to another molecule, e.g transfer of phosphate from ATP to glucose to form glucose-6-phosphate during glycolysis.
Answer:
48.6 g
Explanation:
Given data:
Length of one side = 3 cm
Density of cube = 8.1 g/cm³
Mass of cube = ?
Solution:
First of all we will calculate the volume of cube.
V = length × height × width
V = 3 cm × 3cm× 3cm
V = 27cm³
Now we will determine the mass by using density formula.
d = m/v
d = density
m = mass
v = volume
8.1 g/cm³ = m/ 27 cm³
m = 8.1 g/cm³ ×27 cm³
m = 48.6 g
