Answer:

rise in temperature and the effect it has on our global weather patterns

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.

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.

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.

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.

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.

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:

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.

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

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

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

Answer:

See explanation

Explanation:

Intermolecular forces are forces of attraction that exist between molecules of a substance in a particular state of matter.

The dominant intermolecular force of attraction in H2O is the hydrogen bond. The hydrogen bond exists between molecules of a substance when the substance is made of hydrogen atoms bonded to atoms of a highly electronegative element. Hence, strong hydrogen bonding accounts for the high boiling point of water.

The magnitude of hydrogen bonding between molecules depends on the electro negativity of the atoms to which hydrogen is bonded.

The more the electro negativity of the atoms to which hydrogen is bonded, the greater the magnitude of intermolecular hydrogen bonding.

Since the electro negativity of elements decrease down the group, the strength of intermolecular hydrogen bonding between the molecules decreases as follows;

H2O> H2S> H2Se> H2Te

It's nitrogen

Explanation:

cuz it has valence 3 and  a diatomic gas at room temperature

Element X must be nitrogen.

The 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.

Axit      

Explanation:

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.
