O C. They are both made of carbohydrates.
O D. They are both polysaccharides.
Polymers can be found naturally in plants as well as in animals or can be human made or synthetic. Here nucleic acids and proteins similar, because They are both polymers. The correct option is A.
What are polymers?The large macromolecules which are formed by the combination of a large number of smaller subunits called the monomers are defined as the polymers. The polymers are present all around us, also in DNA which is a naturally occurring biopolymer.
Proteins, starch, cellulose, etc. are natural polymers. Nucleic acids are the polynucleotides of very high molecular mass formed from the linking of nucleotide units. They are important biopolymers for the transmission of hereditary character.
Proteins are also complex molecules from the amino acids and they are responsible for the metabolism, defense, etc. Keratin is a protein found in the outer part of skin.
Thus the correct option is A.

There is 25.3 mL of the sulfuric acid solution; the sulfuric acid concentration is 2.30 M. Your base solution is 1.00 M. What is the volume in mL of base that is required to complete the neutralization of the acid
Answer:
The volume of the base is 0.05819·x L, where x is the number of moles of base that combines with one mole of sulfuric acid
Explanation:
The volume of the sulfuric acid, V = 25.3 mL = 25.3 × 10⁻³ L
The concentration of the sulfuric acid, c = 2.30 M
The concentration of the base, [tex]c_{base}[/tex] = 1.00 M
Let the mole ratio of the acid to base be 1 : x
The number of moles of sulfuric acid present, n = c × V
∴ n = 2.30 M/L × 25.3 × 10⁻³ L = 0.05819 moles
The number of moles of sulfuric acid present, n = 0.05819 moles
1 mole of sulfuric acid combines with x moles of base
Therefore, 0.05819 moles of sulfuric acid will combine with 0.05819·x moles of base
The number of moles of base, [tex]n_{base}[/tex] = 0.05819·x moles
Therefore, the volume of base, [tex]V_{base}[/tex] = [tex]n_{base}[/tex]/[tex]c_{base}[/tex]
∴ [tex]V_{base}[/tex] = 0.05819·x/1 ≈ 0.05819·x L
The volume of base, [tex]V_{base}[/tex] ≈ 0.05819·x L.

1) Osmium reacts with oxygen in the air to form a highly toxic chemical called osmium oxide
+=
+=
Answer:
Solid Osmium transition metal reacts with Oxygen gas to produce solid Osmium tetroxide.
Os(s) + 2O₂(g) -> OsO₄(s)
Explanation:
Osmium tetroxide is another way of writing Osmium (VIII) oxide.
Leaving powdered osmium exposed to air in a room will slowly create osmium tetroxide at room temperature.
Similarly, osmium tetroxide vapor will readily be released from a liquid solution at room temperature.

Aluminum reacts with a certain nonmetallic element to form a compound with the general formula AlX. Element X is a diatomic gas at room temperature. Element X must be __________. Group of answer choices oxygen fluorine chlorine nitrogen sulfur
Answer:
It's nitrogen
Explanation:
cuz it has valence 3 and a diatomic gas at room temperature
Element X must be nitrogen.
Chemical reactionThe general formula AlX indicates that aluminum (Al) is reacting with a nonmetallic element represented by X to form a compound.
Since the compound AlX is said to be a diatomic gas at room temperature, it aligns with nitrogen (N2), which is a diatomic gas and a nonmetal.
Among the given options, nitrogen is the diatomic gas that best fits this description.

What is Halo form reaction?
Answer:
Explanation:
I willl go into a bit of detail on the haloform reaction. So the first few steps involve forming an enolate using the base, typically NaOH. THe enolate and go on to do alpha halogenation 3 times. After that, is leaves a trisubstituted alpha methyl carbon with a specific halogen. This is a good leaving group in itself and can carbonyl nucleophillic substitution and turn into a carboxylic acid with a CHZ3- byproduct where Z represents a halogen.

Answer:
SiCl4 + 4H2O--->Si(OH4)+4HCl
Explanation:
if you put a 4 in front of H2O it means you will have 8 hydrogens(you multiply 4 by 2) then the oxygens will be 4..on the other side that hydrogen in the brackets holds it's on 4 so that 4 isn't for both the hydrogen and the oxygen...and if you put a 4 in front of the HCl that simply means it's for both the hydrogen and oxygen.

Mother is frying fish in the kitchen. The aroma of fried fish can be smelled by Sofea who is sitting in the living room. Explain how the aroma of the fried fish reach the living room.
Answer:
through process of diffusion
Explanation:
air particles and odours move freely in all directions and eventually spreads out thus reaching the sitting room
The process of diffusion causes the particles of the aroma of the fried fish to reach the living room.
What is diffusion?Diffusion can be described as the net movement of anything such as molcules, or energy from a region of higher concentration to a region of lower concentration. Diffusion is generally driven by a gradient in Gibbs free energy or chemical potential.
The concept of diffusion can be used in fields such as physics, chemistry, biology, sociology, economics, and finance. The central idea of diffusion is common that a substance undergoing diffusion spreads out from a point or location at which there is a higher concentration of that substance.
A gradient can be defined as the change in the value of an amount such as concentration, pressure, or temperature with a change in another variable, distance.
A change in concentration over a distance is known as a concentration gradient, and a change in pressure over a distance is known as a pressure gradient.
The Latin word diffusion means "to spread out." Therefore, the aroma of the fried fish diffuses and reaches to lining room.

c. The reaction Br2 (l) --> Br2 (g) has ΔH = 30.91 kJ/mol and ΔS = 93.3 J/mol·K. Use this information to show (within close agreement) that the boiling point of bromine is 332 K.
The boiling temperature of bromine is 331.29 K
Explanation:
From the question given above, the following data were obtained:
Br₂ (l) —> Br₂(g)
Enthalpy change (ΔH) = 30.91 KJ/mol
Entropy change (ΔS) = 93.3 J/mol·K
Boiling temperature (T) =?Next, we shall convert 30.91 KJ/mol to J/mol. This can be obtained as follow:
1 KJ/mol = 1000 J/mol
Therefore,
30.91 KJ/mol = 30.91 × 1000
30.91 KJ/mol = 30910 J/mol
Thus, 30.91 KJ/mol is equivalent to 30910 J/mol.
Finally, we shall determine the boiling temperature of bromine. This can be obtained as follow:
Enthalpy change (ΔH) = 30910 J/mol
Entropy change (ΔS) = 93.3 J/mol·K
Boiling temperature (T) =?ΔS = ΔH / T
93.3 = 30910 / T
Cross multiply
93.3 × T = 30910
Divide both side by 93.3
T = 30910 / 93.3
T = 331.29 K
Thus, the boiling temperature of bromine is 331.29 K
