Answer:...intercellular receptors
Explanation:
Lipophilic hormone also known as lipid-soluble hormones can pass through the cell's plasma membrane, to bind to intracellular receptors, so as to effect change in gene expression.
Answer:
the maximum safe operating temperature the engineer should recommend for this reaction is 616 °C
Explanation:
Given the data in the question;
First we calculate the Volume of the steel cylinder;
V = πr²h
radius r = Diameter / 2 = 27 cm / 2 = 13.5 cm
height h = 32.4 cm
so we substitute
V = π × ( 13.5 cm )² × 32.4 cm
V = π × 182.25 cm × 32.4 cm
V = 18550.79 cm³
V = 18.551 L
given that; maximum safe pressure P = 3.10 MPa = 30.5946 atm
vessel contains 0.218kg or 218 gram of carbon monoxide gas
molar mass of carbon monoxide gas is 28.010 g/mol
so
moles of carbon monoxide gas n = 218 gram / 28.010 g/mol = 7.7829 mol
we know that;
PV = nRT
solve for T
T = PV / nR
we know that gas constant R = 0.0820574 L•atm•mol⁻¹ K⁻¹
so we substitute
T = ( 30.5946 × 18.551 ) / ( 7.7829 × 0.082 )
T = 567.5604 / 0.6381978
T = 889.317387 K
T = ( 889.317387 - 273.15 ) °C
T = 616.167 ≈ 616 °C { 3 significant digits }
Therefore, the maximum safe operating temperature the engineer should recommend for this reaction is 616 °C
Answer: dry ice is a solid which makes it different from a gas
Explanation:
Can you show me the atoms please? I would be able to help.
Here we have to get the reason for continues changing of the atomic model over the past 200 years.
The reason for changing the atomic model is-The results of further experimentation helped to revise and improve the model.
The development of atomic model occurred step-wise as given below-
1. Rutherford atomic model, which explained the result of electrical neutrality of atoms by discovering the nucleus of atom, but it cannot explain the stability of accelerated charge particle i.e. electron.
2. The concept of radiation was later explained by Planck's quantum theory.
3. After this Bohr introduce another concept of atomic model which can explain the stability of the electron and also a part of the spectrum of the atom, but it has the demerits on the fine structure of the atom and heavier elements.
4. Sommerfeld extended the Bohr's theory, which gave the light on the elliptical orbits of a certain orbit.
5. After this to explain the wave-particle duality of the electron, the wave mechanical concept was proposed by deBroglie's, which further extended to the uncertainty to localize the electron and its velocity at a time which is Heisenberg uncertainty principle.
6. Later the quantum mechanical approach to explain the atomic model Schrodinger proposed equation which effectively explain most of the phenomenon of the atoms.
