How do the physical and chemical properties of wood contribute to the function of the synthetic products made of wood?
Answers
Wood's tensile strength is reduced. Another risk factor for the strength of the wood is the loading time. The rigidity of wood is affected by temperature.
What is wood?Wood is one of the most common and useful natural materials. It is the main tissue that supports and conducts nutrients in trees and other plants. Wood comes in a variety of colours & grain patterns and is produced by numerous botanical species, comprising both gymnosperms & angiosperms.
Its wood's tensile strength is reduced. Another risk factor for the strength of the wood is the loading time. The rigidity of wood is affected by temperature. Unfavourable weather and unexpected temperatures will have an impact on the wood's strength. Among its attributes are mechanical, chemical, and physical qualities.
Therefore, wood's tensile strength is reduced. Another risk factor for the strength of the wood is the loading time.

Which of the following statements is true about single-replacement reactions?
1)They are restricted to metals.
2)They involve a three products.
3)Both the reactants and products consist of an element and a compound.
4)Any metal replaces any other metal.
Answers
Explanation:
i think is, They involve a three products.
The statement which is true about single-replacement reactions are:
3) Both the reactants and products consist of an element and a compound.
Single-replacement reactions :These reactions are also known as single displacement reactions, in this type, the ions of the metals or elements get exchanged with the other element and lead to the formation of a new product.
Example: [tex]2K+2H_2O--- > 2KOH+H_2[/tex]
The ions of water get exchanged with potassium and form a new salt that is potassium hydroxide.
Thus, option 3 is correct.

According to the text, which amino acid(s) contains a side chain..
a. in which molecules form covalent disulfide bridges with each other?
b. that is hydrophobic?
c. that forms hydrogen bonds?
d. that is basic?
Answers
Answer:
(b) that is hydrophobic
Explanation:
e.g, alanine
Cause, Alanine possess hydrophobic side chain and the most appropriate answer is (d) part......
Alanine is an aliphatic amino acid, because the side-chain connected to the α-carbon atom is a methyl group (-CH3), alanine is the simplest α-amino acid after glycine. The methyl side-chain of alanine is non-reactive and is therefore hardly ever directly involved in protein function..

T = 100 K
Required
the value for ΔG
Solution
The spontaneous process of a reaction is based on 2 factors :
enthalpy change ΔH decreases and entropy change ΔS increasesΔG=ΔH-T.ΔS

Using principles of atomic structure, explain why the atomic radius of Te is less than the ionic radius of Te2− . Photoelectron spectroscopy data for the 1s sublevel of Te and the 1s sublevel of O are represented below. In terms of Coulomb's law and atomic structure, explain why the peak for O is positioned so far to the right of the peak for Te .
Answers
Answer:
See explanation
Explanation:
Let us recall that a negative ion is formed by addition of electrons to an atom. When electrons are added to the atom, greater interelectronic repulsion increases the size of the Te^2− hence it is greater in size than Te atom. Therefore, the ionic radius of Te^2− is greater than the atomic radius of Te.
In the second question, oxygen is positioned so far to the right because it has a far smaller nuclear charge compared to Te. Hence in the PES spectrum, the 1s sublevel of oxygen lies far to the right of that of Te.
Using principles of atomic structure, the reason why the atomic radius of Te is less than the ionic radius of Te²− is because of the Electrostatic force of repulsion between the negatively charged electrons of Te²- thereby causing the ion to be bigger than the neutral atom.
We must remember that negative ions are formed as a result of the addition of electrons to an atom.On this note, the electrostatic force of repulsion between the negatively charged electrons of Te²- ion becomes greater. Hence, the Te atomic radius is less than the ionic radius of the Te²- ion.By considering the second scenario, the element oxygen is positioned so far on the right because it has a very much smaller nuclear charge compared to Te.
As a result, in the PES spectrum, the 1s sublevel of oxygen lies far to the right of the 1s sublevel of Te.

What happens when molten material travels along the underside of the crust?
Answers
Answer:
Explanation:
The earth is comprised of denser materials such as iron and nickel and other siderophile elements in the core and silicate materials in the mantle. The temperature at the core of the earth is extremely high that generates a force, that allows the molten materials (magma) to rise up from the bottom of the mantle towards the crust, in the form of convection currents. This upward movement of magma forces the lithospheric plates to move.
Thus, magma rises from the bottom of the mantle towards the crust.
