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.

What is the molecular formula of the compound with a molecular weight of 112 g/mol and percent composition: 85.6% C and 14.4% H?
Select one:
a. C2H4
b. CH2
c. C4H8
d. C8H16
Answer:
Molecular formula = C₈H₁₆
Explanation:
Given data:
Percentage of hydrogen = 14.4%
Percentage of carbon = 85.6%
Molecular formula = ?
Molecular weight = 112 g/mol
Solution:
Number of gram atoms of H = 14.4/ 1.01 = 14.26
Number of gram atoms of C = 85.6/ 12 = 7.13
Atomic ratio:
C : H
7.13/7.13 : 14.26/7.13
1 : 2
C : H = 1 : 2
Empirical formula is CH₂
Molecular formula:
Molecular formula = n (empirical formula)
n = molar mass of compound / empirical formula mass
n = 112 / 14
n = 8
Molecular formula = n (empirical formula)
Molecular formula = 8 (CH₂)
Molecular formula = C₈H₁₆

Each electron can be represented by 4 quantum numbers. The two electrons in the outermost level of strontium are designated at 5 s . How many quantum numbers would these two electrons have in common
Explanation:
They are both in shell 5 and subshell s.
Since s only has 1 orbital, they also have the same orbital number.
But they have different magnetic spins.
Hence 3 out of 4 quantum numbers are in common.

Answer: 3.613x10^24
Explanation: Avogadro’s number represents the number of atoms in one mole of substance: 6.022x10^23 atoms/mole. Multiplying the number of moles by this number reveals that, in this sample, 3.613x10^24 atoms of methane are present.
Answer: A
Explanation: When using dimensional analysis, always put similar unit-ed numbers diagnolly from each other so they 'cross out'
For example, If you had 1 mol of gold and you wanted to convert it to grams using gold's molar mass, 196.97 g/mol, it would look like this:
Start with the given number over nothing:
[tex]\frac{1 mol Au}{} *\frac{ }{ }[/tex]
Then add your conversion, in this case the molar mass, with the MOLES on the BOTTOM, so they are diagnol with the 1 mol of Au
[tex]\frac{1 mol Au}{ } *\frac{196.7 g Au}{1 mol}[/tex]
Always have the top right in your dimensional analysis be in the units that you are solving for. In this case, we went from moles to grams, so grams is in the top right.
Hope this helps!
Also, 6.02 x 10²³ is otherwise known as avogadros number- it is used when you are converting something from moles to molecules (or particles). For example, if instead we were going from moles of gold to molecules of gold, our dimensional analysis would look like this:
[tex]\frac{1 mol Au}{ } *\frac{6.02 x 10^2^3 molecules Au}{1 mol}[/tex]

Nuclear fusion reactions release more energy than fission reactions while also generating less waste. However, nuclear fusion reactors are not currently used to generate electricity.
What is the main reason for this?
Nuclear fusion reactions release high energy and required tremendous temperature of nuclear reactors is the main reason for not used to generate electricity.
What are nuclear reactions?Nuclear reactions are those reactions which are taking place in the nucleus of any unstable atom and produces energy.
As in the question it is given that nuclear fusion reactions releases more energy and less wastage, but this energy are releases in the tremendous amount which can be proved harmful for the environment and the humans. To carry out this reaction we have to maintain the very high temperature of nuclear reactors of about 6 times greater than sun's temperature, which is not possible manually.
Hence, high temperature of nuclear reactors and high amount of energy released is the main reason.

How do we get heat from the sun?
Answer:
When the Sun's energy moves through space, it reaches Earth's atmosphere and finally the surface. This radiant solar energy warms the atmosphere and becomes heat energy. This heat energy is transferred throughout the planet's systems in three ways: by radiation, conduction, and convection.
Explanation:
Answer:
The sun radiates energy in all directions. Most of it dissipates into space, but the tiny fraction of the sun's energy that reaches Earth is enough to heat the planet and drive the global weather system by warming the atmosphere and oceans. The delicate balance between the amount of heat Earth receives from the sun and the heat that Earth radiates back into space makes it possible for the planet to sustain life.

Aluminum nitrate reacts with sodium hydroxide to form a precipitate of aluminum hydroxide. What mass of aluminum hydroxide will precipitate when 35.5 mL of 0.145 mol/L aqueous aluminum nitrate is mixed with 44.2 mL of 0.215 mol/L aqueous sodium hydroxide?
Answer:
The mass of aluminum hydroxide that will precipitate when 35.5 mL of 0.145 mol/L aqueous aluminum nitrate is mixed with 44.2 mL of 0.215 mol/L aqueous sodium hydroxide is approximately 0.247 grams
Explanation:
The given parameters are;
The volume of 0.145 mol/L aqueous aluminum nitrate in the reaction = 35.5 mL
The volume of 0.215 mol/L aqueous sodium hydroxide in the reaction = 44.2 mL
The balanced chemical equation for the reaction is given as follows;
Al(NO₃)₃ (aq) + 3NaOH (aq) → Al(OH)₃ (s) + 3NaNO₃ (aq)
Therefore;
1 mole of Al(NO₃)₃, reacts with 3 moles of NaOH to form 1 mole Al(OH)₃, and 3 moles of NaNO₃
The number of moles of aqueous aluminum nitrate in the reaction = 35.5/1000 L × 0.145 mol/L = 0.0051475 moles
The number of moles of aqueous sodium hydroxide in the reaction = 44.2/1000 L × 0.215 mol/L = 0.009503 moles
Therefore, 0.009503 moles NaOH will react with 0.009503/3 moles Al(NO₃)₃ to form 0.009503/3 moles of aluminum hydroxide precipitate
The molar mass of aluminum hydroxide = 78 g/mol
Therefore, 0.009503/3 moles of aluminum hydroxide weighs 78 × 0.009503/3 = 0.247078 grams
The mass of aluminum hydroxide that will precipitate out ≈ 0.247 grams.

What is the value for AG at 100 Kif AH = 27 kJ/mol and AS = 0.09 kJ/(mol-K)?
A. AG = 2700 kJ/mol
B. AG = -36 kJ/mol
C. AG = 0 kJ/mol
D. AG = 18 kJ/mol
Answer:
ΔG = 18KJ/mol
Explanation:
Given data:
ΔS = 0.09 Kj/mol.K
ΔH = 27 KJ/mol
Temperature = 100 K
ΔG = ?
Solution:
Formula:
ΔG = ΔH - TΔS
ΔH = enthalpy
ΔS = entropy
by putting values,
ΔG = 27 KJ/mol - 100K(0.09 Kj/mol.K)
ΔG = 27 KJ/mol - 9 KJ/mol
ΔG = 18KJ/mol
