A 1.00 mole of Sulfuric acid (H₂SO₄) contains the largest number of atoms (7 atoms/molecule). Option B is correct.
To determine which of the given compounds contains the largest number of atoms in 1.00 mole, we need to consider the number of atoms in each compound.
1.00 mole of NH₃ contains:
1 mole of N atoms (1 atom/molecule)
3 moles of H atoms (3 atoms/molecule)
Total atoms = 1 + 3 = 4 atoms/molecule
1.00 mole of H₂SO₄ contains:
2 moles of H atoms (2 atoms/molecule)
1 mole of S atoms (1 atom/molecule)
4 moles of O atoms (4 atoms/molecule)
Total atoms = 2 + 1 + 4 = 7 atoms/molecule
1.00 mole of HBr contains:
1 mole of H atoms (1 atom/molecule)
1 mole of Br atoms (1 atom/molecule)
Total atoms = 1 + 1 = 2 atoms/molecule
Therefore, 1.00 mole of H₂SO₄, contains the largest number of atoms.
Hence, B. is the correct option.

what are the three molecules that are attached to the plasma membrane, and what are their roles/ functions?
Answer:
Ans:
*Carbohydrates
*Proteins
*Cholesterol
Explanation:
The plasma membrane is a structure that has several distinct roles in the cell
The plasma membrane is mainly composed of the phospholipid Bilayer, which is a layer of two sheets located in the internal and external parts. The Phospholipids are said to be Amphipathic because they have both properties of Hydrophobic and hydrophilic
*The Carbohydrate Molecules attach to the Plasma Membrane such as to the lipids and Proteins:
when They attach to the Proteins, they are known as glycoproteins, and they help in cell recognition, when they attach to the lipids, they are known as Glycolipids
*Protein Molecules play an important role in transport system such as Carrier Proteins
*Cholesterol Molecules help in balancing the Fluidity of the plasma membrane

Which statement below describes the behavior of a Molecules when a substance changes from a gas to liquid
Answer:
As a substance changes from a solid to a liquid to a gas, its molecules first the molecules are moving fast enough, they are able to "escape." They leave the surface of the liquid as gas molecules. Evaporation is not the only process that can change a substance from a liquid to a gas. The same change can occur through boiling.

The given statement is False.
Some acids like acetic acid and tartaric acid can be tasted.
Organic acids, such as acetic, citric, malic, and fumaric acids in fruits and vegetables, and tartaric acid in wine, contribute significantly to the sour flavor of foods and beverages. Many inorganic acids taste sour in dilute solutions.
Tartaric acid is fairly water soluble and has a pronounced tart flavor. Tartaric acid is present naturally in grapes and bananas and has been shown to improve the flavor of grape and lime-flavored beverages. Tartaric acid may aid in the treatment of glucose intolerance and digestion.
Acetic acid is a colorless liquid having a sour flavor. Although it is most frequently associated with vinegar, this acid has a wide range of different applications in a variety of industries. Acetic acid is a colorless liquid that is composed of chemical compounds.

what is the molarity of a koh solution if 25.0 ml neutralizes 35.0 ml of a 0.200 m hcl solution?
If 25.0ml neutralizes 35.0 ml of a 0.200M HCl solution, the molarity of KOH solution is 0.28M
The reaction between KOH solution and HCl is written below.
[tex]HCl + KOH \rightarrow KCl + H_2O[/tex]
Volume of KOH, [tex]V_B[/tex] = 25.0 ml
Volume of HCl, [tex]V_A=35.0 ml[/tex]
Molarity of HCl, [tex]C_A=0.200 M[/tex]
Molarity of KOH, [tex]C_B=?[/tex]
Number of moles of HCl, [tex]n_A=1[/tex]
Number of moles of KOH, [tex]n_B=1[/tex]
The mathematical equation for neutralization reaction is:
[tex]\frac{C_AV_A}{C_BV_B} =\frac{n_A}{n_B}[/tex]
Substitute [tex]C_A=0.200 M[/tex], [tex]n_A=1[/tex], [tex]n_B=1[/tex], [tex]V_B[/tex] = 25.0 ml, and [tex]V_A=35.0 ml[/tex] into the equation above in order to solve for [tex]C_B[/tex]
[tex]\frac{0.2 \times 35}{C_B \times 25}=\frac{1}{1} \\\\25C_B=7\\\\C_B=\frac{7}{25} \\\\C_B=0.28M[/tex]
Therefore, the molarity of KOH solution is 0.28M
