The wood can't do the same function as done by the water and glass in the same virtual experiment due to its different chemical composition.
The light will not pass through the wood due to its translucent behaviour that prevents light to pass through it as compared to water and glass which are transparent materials and light can easily pass through it.
So using wood as a bottom material instead of glass and water will not perform the same function as perform by water and glass in the same virtual experiment so we can conclude that wood can't perform the same function in the experiment.

Ammonium sulphate + __________________ potassium sulfate + ammonia + water
Please fill in the blank.
Answer:
Potassium Hydroxide Solution =
or
Potassium Hydroxide =
Since we know the products and one of the reactions, we can work backward to discover what the other reactant may be.
As it is in the question, we can map the reactants and product:
Reactants Product
Ammonium Ammonia
Sulfate Sulfate
________ Potassium
________ Water
Since the reaction will yield Potassium and water, the likely reactant is Potassium Hydroxide (KOH). This is because we know that Ammonium lost a Hydrogen atom that could combine with the Hydroxide radical to form water.
This becomes clear when we consider the net ionic equation:
Ammonium sulphate + Potassium Hydroxide → potassium sulfate + ammonia + water
if we write this a balanced chemical equation:
(NH₄)₂SO₄ + 2KOH → K₂SO₄ + 2NH₃ + 2H₂O
if we write the reaction as an ionic equation
2NH₄⁺ + SO₄⁻ + 2K⁺ + 2OH⁻ → 2K⁺ + SO₄⁻ + 2NH₃ + 2H₂O
if we remove the ions that appear on both the reactant and product side (spectator ions)
2NH₄⁺ + 2OH⁻ → + 2NH₃ + 2H₂OI need a catchphrase for the element Boron as a superhero describing its traits!

What is the most abundant type of protein in egg white? What do you think its purpose is?
Answer: Ovalbumin (Albumin)
Explanation:
The albumen (egg white) is composed of almost 60% of the protein ovalbumin. It's the main source of proteins for tissue synthesis in the embryo. It acts as a storage protein, storing ions and amino acids necessary for embryonic development.
There are four different proteins present in egg white. In which the most abundant protein is ovalbumin present in 54 %.
What are proteins?Proteins are biomolecules very essential for life. Proteins are made of a number of amino acids. Amino acids join together to form peptides and large number of peptides constitute a protein.
Essential amino acids have to be up taken from diet and non-essential will be produced inside the body.
Proteins are the major substances to build up our body. There are essential and non essential amino acids. Nails and hair are made of keratin protein. Milk contains the protein called lactine.
Similarly the protein in curd is casein. The proteins in egg white are ovalbumin, ovotransferrin, ovomucin and ovomucoid. In which ovalbumin is most abundant.

It takes 40 mL of 0.10 M of hydrochloric acid (HCl) to neutralize 50 mL of sodium hydroxide (NaOH) for the following chemical reaction
HCl + NaOH → NaCl + H2O
The concentration of sodium hydroxide is _____.
0.125 M
0.08 M
0.10 M
0.04 M
Answer:
0.08 M
Explanation:
here...
1. water and a salt
2. Magnesium hydroxide reacts with HCl to produce a solution that is neutral.
3. titrant
4. 0.08 M
5. indicator
{quizlet: captncrun}
The concentration of sodium hydroxide is 0.08 M. The correct option is the second option 0.08 M
From the question,
We are to determine the concentration of sodium hydroxide
The given reaction is
HCl + NaOH → NaCl + H₂O
This means
1 mole of HCl is required to completely neutralize 1 mole of NaOH
To determine the concentration of sodium hydroxide,
We will use the formula
[tex]\frac{C_{A}V_{A} }{C_{B}V_{B}} = \frac{n_{A}}{n_{B}}[/tex]
Where
[tex]C_{A}[/tex] is the concentration of acid
[tex]C_{B}[/tex] is the concentration of base
[tex]V_{A}[/tex] is the volume of acid
[tex]V_{B}[/tex] is the volume of base
[tex]n_{A}[/tex] is the mole ratio of acid
[tex]n_{B}[/tex] is the mole ratio of base
From the give information
[tex]C_{A} = 0.10 \ M[/tex]
[tex]V_{A} = 40 \ mL[/tex]
[tex]V_{B} = 50 \ mL[/tex]
From the balanced chemical equation
[tex]n_{A} = 1[/tex]
[tex]n_{B} = 1[/tex]
Putting the above parameters into the formula, we get
[tex]\frac{0.10 \times 40}{C_{B} \times 50} = \frac{1}{1}[/tex]
Then
[tex]C_{B} \times 50 = 0.10 \times 40[/tex]
∴ [tex]C_{B}=\frac{0.1 \times 40}{50}[/tex]
[tex]C_{B}=\frac{4}{50}[/tex]
[tex]C_{B}=0.08[/tex]
Hence, the concentration of sodium hydroxide is 0.08 M. The correct option is the second option 0.08 M

Which of the following particles are found in the nucleus of an atom? (Select all that apply).electronsprotonsneutronscompounds
Answer:
protons and neutrons
Explanation:
Neutrons and protons are the particles that are found in the nucleus of an atom.
What are protons and neutrons?Protons and neutrons are subatomic particles. They are present in the nucleus of an atom and constitute most of the mass of the atom. There are three kinds of subatomic particles that are present in an atom.
These are -
Electrons: Electrons are negatively charged particles. These are present in the atomic shells of the atom. The number of electrons in the last shell of the atom constitutes the valency of the atom. Protons: Protons are positively charged particles. These are present in the nucleus of the atom.Neutrons: Neutrons are neutral molecules with no charge. These are also present in the nucleus of the atom.Since most of the mass of the atom, in the form of protons and neutrons, is present in the nucleus, the mass number is denoted as the sum of the number of protons and neutrons. Protons and neutrons together are sometimes also called nucleons.
Therefore, neutrons and protons are present in the nucleus of an atom.
